In case you didn't know it, spam levels have increased dramatically this week. For the first time in about a year, my own spam level has reached 60%. This is up 12% from last week. While the actual amount of spam has increased, the subjects and scams have not changed much. Only the percentages by category are changed this week.

For those who haven't read my spam reports before, I employ an email screening program named MailWasher Pro to act as a filter for known, or suspected spam, scams and virus threats. I obtain statistics at the end of each week, for each category of spam, based upon filters I write and publish (for other MailWasher Pro users).

The number of threats arriving in spam email was greatly reduced from the previous month. There were just a handful of ACH and Wire Transfer Rejected scams. They all contained links leading to Russian, Romanian, or Ukrainian malware servers. All spam for pirated software is still hosted on Ukrainian domains, ending in .COM.UA. Most of the rest of the spam this week was hosted on Russian .RU domains. This is especially true for the numerous Russian Bride online dating scams.

Let's look at my spam statistics for the week ending Oct 30, 2011, as obtained from my anti-spam program: MailWasher Pro.

Spam is definitely increasing, compared to one month ago. For the last month it hovered around the 40% level. Now, it it approaching 50% of my incoming email. This may not jive with your figures, but my amount of good mail is fairly consistent, so my spam percentages are measurable.

Last summer saw spam levels drop way down, but I am not surprised at this constant increase. New spammers are being recruited and my guess is that the spam class of 2011 has graduated. These fools pay to get into the spam game, hoping to find enough suckers to make a big profit. Spammers are paid for leads, sales, credit card number theft and computer infections.

The biggest categories have not changed much over the last few years. I saw a lot of junk mail for Fake pharmaceuticals, male enhancement pills, weight loss capsules, pirated software, fake diplomas and some Nigerian 419 and lottery scams. What is interesting is the resurgence of Russian Bride dating scams.

The worst threats delivered via email were ACH fraud scams, containing links leading to infection of computers. The predominant infection from following the links in these scams is the Zbot, a.k.a Zeus Trojan, plus a Botnet installer. The Zeus hides and watches for you to login to your financial institution, then steals your credentials and money. it is also used to commit identity theft. I have a custom spam filter that blocks ACH scams.

Almost all of the spam I received last week had links to Russian or Ukrainian domains. They don't even try to cloak the links. Lax enforcement in Russia and The Ukraine makes it relatively easy for counterfeiters, fake pharmacies and software pirates to conduct illegal or shady businesses, without much fear of arrest. There are some high level arrests, now and then, but they are just the tip of the iceberg. There are more Russian spammers and Bot-Masters than their police can investigate. For every top spammer busted, five more seem to take his place.

Let's look at my spam statistics for the week ending Oct 23, 2011, as obtained from my anti-spam program: MailWasher Pro.

I was reading my website's raw access logs today and saw that one visitor arrived on my blog when he or she searched Google for this phrase: ach+payment+canceled+spam+how+to+stop. This article will offer suggestions to block such messages from your inbox.

First of all, you need to understand that you are not alone in being a scam and spam recipient. Almost everybody who sends, receives, forwards or replies to any email message will probably end up on some spam database eventually. Master Spammers compile email address databases using various means. Then, these addresses are sorted by country and sold to other, second level spammers. These spammers then rent the use of botnets to blast out ginormous amounts of spam email, to promote various products and services, for which the spammers are affiliates (paid by the sale, or per infection, or referral).

The ACH payment canceled scam which my visitor was asking about is not your typical type of spam message. It comes under the category I call "mal-mail," meaning it contains either a malware laden attachment, or a link to malware exploit attacks or downloads. This is a very dangerous class of email to allow into your computer's email client.

Here are some methods you can try to use to block the ACH scam emails from your inbox.

Despite the takedown of several of the top spam botnets this year, spam levels have remained at the same level of 40%. Most spam this week was still promoting Russian and Ukrainian domains, pushing counterfeit drugs, pirated software, replica ripoff watches, malware exploits and dating scams.

There is a trend that began developing a few weeks ago. That is the registration of spam domains ending in .com.ua, which is a new type of Ukrainian domain. The domains being spamvertised with links ending in ".com.ua" are spamming pirated software, fake watches, Russian and Ukrainian dating scams, fake Cialis, Viagra and other illegal to import (into the US and Canada) prescription drugs.

There was a big decline in the amount of spam emails that actually carried a malware payload in an attachment. They were replaced with several threats that use links to exploit their victims, rather than attached files. The end result is the same for those tricked into clicking those links: bots and various Trojan downloaders.

I compile my spam statistics from my spam screening program MailWasher Pro, which I use to filter out spam, malware attachments and dangerous links, before downloading any messages to Windows Live Mail, which is my desktop email client. The categories represent custom spam filters which I write and publish.

The following are a list of categories of spam received this week, ranked by percentage, highest first.

Another week has gone by and spam levels have remained fairly static, at the same level (just under 40%) as the previous week. Most spam this week was promoting Russian and Ukrainian domains, pushing counterfeit drugs, pirated software, replica ripoff watches and dating scams.

Thankfully, there was a big decline in the number of scam emails containing malware in attachments, or at the end of hyperlinks. I did see a lot more spam messages for pirated software, all hosted on Ukrainian domains, ending with .com.ua. Also on those domains were male enhancement scams, weight loss, and someone named Elina who is looking for a man, but has an email address beginning with Maria.

Not to be left out, there were several Nigerian 419 scams and lots of junk mail for fake Cialis and Viagra. What few ACH Transaction Canceled scams I saw ended about mid-week. I have blogged about these threats numerous times since late August 2011. Search this blog for details about the ACH and FDIC scams leading to malware exploits and botnets.

Why should email archiving be an important part of your company's email management?

Email is an intrinsic part of business communications and today is often the primary means of doing business with customers and communicating internally. Email is also a huge source of corporate and confidential data.

In a fast-paced environment, it's important to have a reliable email system in place as a well as a comprehensive email management strategy to minimize downtime, limit help desk calls, achieve compliance and, have a backup plan should anything go wrong.

One important facet of every email management strategy should be email archiving.

With most administrators imposing email quotas on their Exchange server because of storage restrictions and performance issues, employees tend to use Outlook's 'Auto-Archive' function to create PST files. This is often a problematic approach to email management because the administrator either has little control over the locations of the PST files (in some folder on the PC) or they are stored in a network share (with the resultant impact on storage space). Searching for old emails or conversations can be a major undertaking. Administrators simply do not have the time to search individual machines for missing PSTs and, if that PST is corrupt, go through the process to restore that file. If those emails are required for compliance or audit reasons, the administrator will be very concerned - what happens if the email cannot be located?

In small networks where the administrator has a lot more control, PSTs may be acceptable if there is a strict PST policy in place - but not in larger environments. The task to manage PSTs will reach a point where the admin has little control, PSTs are all over the place and the risk of email being lost or corrupted grows exponentially.

One way to address this set of problems and keep everyone happy is to take email storage off the Exchange Server and out of PSTs. This is achieved through email archiving. Administrators will have full control over how and where emails are stored and saved, emails are offloaded from the Exchange server and should the need arise, search for email from on single location with ease. Users, on the other hand, do not have to worry about deleting emails when their quota is reached because every email is stored for them in a central location, easily accessible via a web interface or through their email client (with the appropriate connector to the database).

While this addresses performance, storage and data loss issues, email archiving also makes the legal department happy because they know that all corporate email is stored in a central repository, is secure and easily searchable.

Email archiving is one element of your email management strategy. There are other important steps such as implementing antivirus and anti-spam at the gateway and on the Exchange Server.

In this post we have outlined how email archiving is a fundamental tool for administrators to manage their email infrastructure and to comprehensively deal with email storage issues, email compliance and e-Discovery, business records, and Exchange server performance.

Over the last couple of weeks there has been a huge spam run with fake ACH canceled transaction notices, all of which came with malware inside attached files. Recipients were urged to open these files to read the failed transaction report. Effective 9/26/11, the same message text is being re-used, with the exception of how the victim is supposed to read the "Transaction Report."

Now, instead of send malware directly as attached files, the criminals behind this scam are providing links to read the "Transaction Report" at the "Nacha.org" website. At least, that is what the links show to the casual observer. If one hovers over these links they learn that the destination is not nacha.org, but a totally different website name. All of the domain names used in the spam run I saw today (9/26/2011) were registered today, with a company calling itself: MELBOURNE IT, LTD. D/B/A INTERNET NAMES WORLDWIDE. Most of the domains are not resolving at this time, but at least one is. That malware serving site is at na-chas-data-info DOT com (do not go there with a standard browser!).

Upon landing on this still active website, hosted on Yahoo.com, they see a fake "NACHA - ACH Transfer Rejected" titled page. Unknown to the victim, a hidden iframe is hijacking the browser away from that fake notice to a server that attacks the browser with the BlackHole Exploit Kit. That server is at: "huntcheerful.com" - hosted at p8p.geo.vip.sp2.yahoo.com.

UPDATE:
As I was typing this the malware account at huntcheerful.com began serving a 503 Service Unavailable notice. I guess that somebody at Yahoo finally read my SpamCop reports against this domain.

It appears that the six domains I reported earlier today have all been taken offline. However, the people behind this scam will keep registering new cheap domain names and will continue to abuse legitimate web hosts to serve malware to as many people that they can trick into clicking on those links.

To protect yourself, your family, and or employees, inform them that the US NACHA organization does not ever contact the public about any failed "ACH" transactions. Neither does anything going by the name ACH ever contact people whose transactions didn't go through. Only your bank will contact you if your check, deposit, or money transfer fails.

Any email about a failed ACH transaction, not coming from your known bank, is a fake and a scam and should be deleted on sight. If someone at your business receives such a notice and isn't sure if it is legitimate, call your bank and ask if a recent transaction has failed, or been canceled by the other party. In 99% of the calls they will tell you no such thing has occurred.

You can add a layer of protection to your email users by creating rules that block all emails claiming to be sent from nacha.net, nacha.org and nacha.us. If you are able to create wildcard rules, block all email from any address at nacha.anything. The email screening program MailWasher Pro, which I use, utilizes regular expressions to blacklist email senders, based on what is listed in the "From" field. The rule I use to block anything from any sender @ nacha.anything is: +@nacha.+

In addition to using blacklisted senders, MailWasher also uses custom filters, which I happen to publish for others to use. A couple of my MailWasher filters already detect, flag and or auto-delete these scams.

Since last Sunday night, Sept 18, my incoming percentage of spam email has dropped slightly, from 36% to 35%. This makes 4 weeks in a row of small, yet steady decreases in spam. Furthermore, the amount of malicious attachments has taken a drastic downturn from the previous few weeks.

With the welcome decline in the number of malware laden attachments, what is left is standard junk email for prescription drugs, illegal to import into the USA, sold without a prescription, from Russian and Ukrainian domains. Also there were many male enhancement (Max-Gentleman) and weight loss scams (pushing HCG pills), as well as the usual batch of fake Viagra and Cialis. Again, these are prescription drugs, and even though they're counterfeit, they are illegal to import into the USA from abroad. There were even a few spam emails selling fake diplomas and a bunch of Nigerian lottery and inheritance 419 scams.

I compile my spam statistics from my spam screening program MailWasher Pro, which I use to filter out spam, malware attachments and dangerous links, before downloading any messages to Windows Live Mail, which is my desktop email client.

While checking incoming email today, I received some new variations of recent malware threats, in email attachments. Upon examining the source codes I found that some are variations of the previous FDIC (Federal Deposit Insurance Corporation) warnings, directly related to the previous few weeks of scams for ACH (Automated Clearing House) canceled transactions notices.

The new scams have the Subject: FDIC message center

There is a new twist to the FDIC scams, which I saw for the first time, today, September 22, 2011. Instead of actual text, they are now using an embedded image to convey a message meant to scare recipients into opening the attached file. This image looks like it might be sent from the FDIC, complete with official logos. Rest assured it is a Photoshopped image, containing words directing victims to open the hostile attachment.

The wording on the first captured FDIC scams of 9/22/11 read as follows:

Dear Customer,
Your account ACH and WIRE Transaction have been temporarily suspended for security reasons due to the expiration of your security version. To download and install the newest installations read the document(pdf) attached below.

As soon as it is setup you transaction abilities will be fully restored.

Best regards, Online Security department, Federal Deposit Insurance Corporation.

Presently, the malware attachment is named "FDIC information" - without any extension. This is an error on the part of the people who composed this template. Rest assured, there is a malware payload inside the attached file, which weighs in at 28,822 bytes. I am certain that the next batch of these scams will contain an extension, such as .pdf, .zip, or .pdf.zip, like the scams of the previous few weeks.

For the second week in a row, I have seen a decline in the overall volume and percentage of spam email. While the percentage is still high, at 36%, it is down 3% from last week. Most spam for counterfeit drugs, fake diplomas, Nigerian 419 scams and replica watches is profit driven by the suckers who respond to spammers' come-ons. But, a large amount is still coming in containing malware in attachments.

The weekend of September 12 through 18 saw a temporary decline of a prolonged spam run for fake ACH failure notices, all containing the Zeus/Zbot Trojan, but it picked back up mid week. Added to the mix of hostile attachments were emails claiming to be invoices and changelogs. they also contain the Zbot banking Trojan and botnet installers.

I obtain my spam statistics form the anti-spam program MailWasher Pro, which I use to filter out spam, malware attachments and dangerous links, before downloading any messages to Windows Live Mail, which is my desktop email client.

After peaking two weeks ago, the volume and percentage of spam in my Inbox has declined again by 2%, to 39%. While most email spam is for counterfeit pharmaceuticals and watches, much of the spam over the past few weeks has contained malicious attachments, or links to exploit attack websites.

The weekend of September 9 through 11 finally saw the (temporary) end of a prolonged spam run for fake ACH failure notices, all containing the Zeus/Zbot Trojan, as well as the almost month long campaign of fake Facebook Friend Requests (with Arabic names in the subject). Those emails were scams and had links to a website that contained both on-page and hidden codes leading to serious malware infections, including the Zbot.

The purpose of the malware attachments and hostile link spam blasts was to infect unsuspecting computer users with key loggers that steal their online banking credentials (and all their money), and to install botnet remote control backdoor software on them.

See my recent posts (listed in the right sidebar) during August and early September, 2011, about the ACH and Facebook scams leading to botnet infections. They, and other articles like them, are also found in my "Spam" category listings.

I use the anti-spam program MailWasher Pro to filter out spam, malware attachments and dangerous links, before downloading any messages to Windows Live Mail, which is my desktop email client.

For the second week in a row, my volume and percentage of spam has passed 40%.This week I saw 41%, which is down just 2% from the week before. Notably, much of the spam either contained malware in attachments, or had links leading directly to malware exploits.

There were two specific classes of malware threats this week, carried forward from last week: the ACH canceled payment-transaction under review scams, containing the Zbot/Zeus banking Trojan, or 2: fake Facebook Friend Requests, leading to the BlackHole Exploit Kit, plus the Zbot and botnet installers. The preceding links are to articles I have already written, explaining these threats and how you can identify them and deal with them.

While the ACH scams seem to have subsided, the Arabic name Facebook Friend Request threats are still persisting, as of the time I published this.

In a nutshell, from August 29, through September 4, I logged the following spam statistics, using MailWasher Pro, by Firetrust.

Total email received: 431
Amount classified as spam: 181
Percentage of spam: 41%
Number matched by my custom filters: 168

It was only a couple of days ago (8/26/2011) that I published a blog article warning people about the threats contained in fraudulent emails claiming that an ACH transfer had been canceled and that the recipient needed to read the report in the attached file.

Beginning at 3 AM, EST, I received four consecutive email scams in 15 minutes, with the subject: "FDIC notification," with the forged sender (the actual "sender" is an infected PC in a spam botnet): "no.reply@fdic.gov," and the following body text:

Dear customer,
Your account ACH and WIRE transaction have been temporarily suspended for
security reasons due to the expiration of your security version. To download and install the newest installations read the document(pdf) attached below.
As soon as it is setup, you transaction abilities will be fully restored.

Best Regards, Online Security departament, Federal Deposit Insurance Corporation.

Like the UPS and ACH scams that preceded it, this scam contains a variant of the Zeus or Zbot Trojan Horse. Its purpose is to install hidden malware that watches for you to visit targeted financial institutions, or your website's control panel, or PayPal, etc. Once you do it intercepts your login credentials and forwards them to the criminals running these scams. Your bank accounts, PayPal accounts and God knows what else may be emptied before you know what hit you!

If you use MailWasher Pro to screen your incoming email for spam and threats in attachments, my custom ZIP Attachment filter will alert you to these and similar threats. Never open the attachments in these scams! Delete the email on sight! Opening these messages will launch the installer for the Zbot. Your PC will not only have the Zeus keylogger installed, but will be made a part of the Botnet from which you received your recruitment message.

After a month of lower email spam volumes, this past week I saw an 11% increase over the previous week, which itself had a 7% increase from the week before. That makes about 18% more spam than two full weeks ago. Most troubling was the fact that a lot of this unwanted email contained malware infected attachments.

The last spam run containing infected attachments was a fake ACH Payment Canceled campaign. It started immediately after a run of fake Uniform Ticket email scams, and both contained the Zeus, a.k.a. Zbot Trojan. This is a hidden keylogger that watches for victims to login to particular banks, Trust companies, PayPal, website control panels, or trading companies. It collects the login credentials and sends them in a data stream to the criminals renting the use of the botnet responsible for sending the spam run. They then steal your money, or hack your websites.

There was also a continuation of the previous week's fake Facebook Friend Requests, containing links leading to direct downloads of Trojans. I wrote about this scam earlier this week, in this article: Beware Fake Facebook Friend Requests, Leading to Malware. To date, all of the requests I have received have contained Arabic names in the subject, but, that may change next time the miscreants behind this scam send another spam blast.

Since I noticed last Sunday that the volume of spam was staying high, I returned to using MailWasher Pro 6.4 to block spam and collect statistics that are easy to view and use in my reports. The current new version, 2011, is fully capable of blocking as much of the spam as the older version, but lacks a statistics page as of this writing.

In case you were wondering, one you can still purchase a licensed copy of MailWasher Pro 6.4, from the Firetrust website. Or, if you don't care about the Statistics readout, but want faster processing, try the new version (same link).

Here are the basic stats for the last week's spam:

Total email received: 501
Amount classified as spam: 219
Percentage of spam: 43%
Number matched by my custom filters: 208
Number caught by my Blacklist: 5
Number identified by DNS Blacklusts: 4

For the last 2 days I have seen a slowly building spam campaign featuring a previously used trick Subject: "ACH Payment (7 numbers) Canceled." The message body is short and sweet, along the line of the following:

The ACH transaction,
recently initiated from your checking account (by you or any other person),
was canceled by the other financial institution.

Rejected transaction

Reason for rejection: See details in the attachment

The From line is usually: "account manager" (account.manager@nacha.net, or account.manager@nacha.us). You will be getting these sent to every one of your email accounts, should you have multiple accounts, like I do. Domains with email are especially hard hit in today's spam campaigns.

The actual "sender" is a PC in a spam botnet, operating under commands from the Bot Master running this show. All reply-to and From information is forged.

The payload in the current crop of malware in attachments is the "Zeus" aka: "ZBot" keylogger Trojan. The installer may also make the victim's computer a member of the same botnet from which their scam message was sent. This perpetuates and increases the size of the botnet and steals money from victims as they log into banks and payment portals targeted by this Zeus variant.

My advice to recipients of one of these, or future variations of these scams, is to phone you bank, or financial institution and ask them to check your account for problem transactions. Note, there have been some spam campaigns that include a fake contact phone number that actually leads to people hired by the criminals running particular campaigns. So, your safest bet is to look-up the number for your bank, or flip over your debit or credit card and call the number listed on it.

Interestingly, these malware in attachments scams began on August 25, just after the previous run of UPS malware scams ended. No doubt, the same botnet is sending both, rotating subjects and body text and attachment names, via templates downloaded to the zombie computers in the botnet.

I delete all such malware laden spam messages, which are automatically flagged by one or more custom spam filters I write, by my email screening program: MailWasher Pro - (learn about MailWasher Pro here). My advice to you is to delete them on sight, without opening them. Phone your bank if you are worried.

If your bank sends you email messages and alerts about problems, the message will include your proper name. None of these scams include any personal names as salutations. That is red flag number one in all such malware and phishing scams.

Stay alert to scams in spams. Do not open any email attachments out of curiosity. Only open attachments you are expecting, from senders you are expecting them from, and then, only if you have modern, fully updated anti-virus/anti-malware protection running on your computers.

Tonight I received what appeared to be a Facebook Friend Request, but it was addressed to an account not associated with Facebook. It was also suspiciously marked with gray icons in MailWasher Pro. This indicates that the anti-spam program wasn't sure if it was good or bad. That set off my alarm bells, because I have a custom filter that identifies all legitimate messages from Facebook as Good.

Luckily for me, I am a spam fighter and suspicion is my modus operandi. Had I been a casual computer user I may have curiously clicked on the link in this email and had my computer infected with a fake Flash Player update, plus an exploit attack kit, within seconds! Then I would have been Phished with a fake Facebook login page! Here is what I saw and what the source code revealed about the email message.

Look at the bold portions of the above headers The first bold line contains the date when this email was delivered to me, by my email server, which is in Utah:
Sun, 21 Aug 2011 21:36:18 -0600

Directly underneath the arrival date is the last Received From line, indicating that the email was delivered to me from the IP address 123.236.135.113. If this email really came from Facebook, the IP address would resolve to one with facebook.com in a "Whois" look-up, and in a reverse IP look-up. However, running a Whois check on this IP address revealed that rather than belong to Facebook, it is registered to Reliance Communications, in Mumbai, India!

Moving down to the next Received line, it says that the email was relayed through LinkedIn. Now, why would Facebook need to use LinkedIn servers? They absolutely would NOT. Also, note that the email was handed to the LinkedIn mail server by the rctengineering.com domain, not Facebook. That domain belongs to a Bell South customer!

Now, look at the date when the email was relayed through the alleged LinkedIn server: Mon, 22 Aug 2011 09:05:39 +0530. That date is almost 12 hours in the future from when my email server in the USA received the message. I ran a look-up of timezones and found that +5:30 belongs to India. That coincides with the IP address of the Received From line at the beginning (which is the final email hand-off). That proves that the message did indeed come from India and was not associated with any Facebook email servers in the USA, or anywhere else.

This week I am changing the nature of my spam report. In all previous articles, I used the "Statistics" from MailWasher Pro, version 6.x. However, this past week I switched to the latest version of MailWasher Pro: 2011. At this time it lacks a "Statistics" readout, so I have compiled my own stats. They reveal some interesting facts about this week's email spam.

The first thing I learned when going over the spam categories, in the MailWasher Pro Recycle Bin, was that the overall volume of spam is way up from last week. For the week ending on August 14, 2011, the total amount of spam received was 128. This week, ending August 21, the total was 175, as of the time I wrote this. Without an exact stat report, I am guesstimating that this represents about 33% of my total email this past week. That would make it about 5% more than last week.

Of these 175 spam emails, 169 were identified by my custom spam filters. Six more were classified as spam manually and inputted into the learning filter, for future detections. The majority of spam was 44 messages touting fake Cialis. This was followed by 24 for counterfeit watches. Next in line was 15 emails promoting male enhancement herbs, then 13 each for weight loss drugs (illegal to import, or use without a face to face prescription; HGC drops) and finally, malware infected botnet Trojans inside zipfiles claiming to be invoices, delivery notices, etc.

Other lesser categories of spam included: Fake Diplomas, Lotteries, African senders, 419 scams, foreign language spam, miscellaneous pharmaceuticals, pirated software, Viagra, known spam domains and subjects, ISO encoded subjects, and my blocked countries filters.

The last major category, the infected zipfiles, are part of a huge attack that has been ongoing for three weeks in a row. Bot Herders, having lost control of millions of zombies, when Microsoft, FireEye, the DOJ and other security research companies decapitated the Bredolab (in October 2010), Coreflood, Rustock, Waledac and other spam-spewing botnets this year, are hard at work rebuilding their armies of robotic malware slaves. Their most successful weapon seems to continue to be exploiting the weakest link in the chain of infection: Human Curiosity. Send out a gazillion spam messages about a pending, or failed delivery. or an alleged speeding ticket, or failure to process an IRS refund or tax form, and thousands of curious, gullible people will open the attached zipfiles to see what the fuss is all about. Poof: they are botted!

This week I saw an increase in the amount of spam hitting my inbox. The percentage of spam was up 7% from the previous week. Actually, the greatest volume of spam occurred from Thursday through today. It was on August 11 that a giant spam run began with malware infected attachments, in scam emails claiming to be from the IRS and UPS.

Due to the huge influx of malware laden attachments in fake IRS ("could not process your return/refund") and UPS ("your package delivered ... print out invoice") messages, the top category last week was Zip file attachments, which led by more than double the amount of the runner up: male enhancement. While the enhancement and enlargement spam is a nuisance, the ones pretending to come from the IRS and UPS were downright dangerous. They contain botnet and key logging Trojans in zip files.

This past 7 days, spam for various types of unsolicited commercial email (UCE) amounted to 28% of my incoming email. This is according to MailWasher Pro, which I use to screen incoming email before downloading it to my desktop email program (Windows Live Mail). I report any spam messages that make it through my auto-delete filters to SpamCop.

Here are some statistics regarding the spam received and categorized, from Aug 7 - 14, 2011. These classifications are based upon my own custom MailWasher spam filters. Most of this spam is automatically deleted by MailWasher Pro and my custom filters. The statistics are obtained from the program's logs.

Statistics Overview

Percentage classified as spam: 28%; +7% from last week
Number of messages classified as spam: 128
Number classified by my custom spam filters: 122
Number and percentage of spam according to my custom blacklist: 3
Number classified as spam by the Bayesian Learning filter: 0
Number classified as spam according to DNS Blocklists (SpamCop, Spamhaus, etc): 1
Number of spam messages seen, reported to SpamCop & manually deleted: 52

This week finally gave me some measurable decline in the amount of spam hitting my inbox. The percentage of spam is down 6% from the previous week and the actual volume is down by even more. This is a reflection of the decline in revenues from spamvertised products and in the recent closure of several spam affiliate payment processors.

As for the top categories of spam, Male Enhancement took first place, followed by counterfeit watches, then fake Viagra, Cialis, weight loss drops, and other scams. There are still a considerable number of bogus diploma spams coming in, so some people must be stupid enough to purchase these worthless documents.

I see a repetitive pattern in certain types of spam, mostly for fake diplomas. The subjects are "RE: Hello" - "RE:Re:Hello" - "RE: RE:News" and similar. My Diploma and other existing filters pick them off based on the body text, with zero mistakes.

This past 7 days, spam for various types of unsolicited commercial email (UCE) amounted to 21% of my incoming email. This is according to MailWasher Pro, which I use to screen incoming email before downloading it to my desktop email program (Windows Live Mail).

This week, my incoming spam level dropped 1% from last week. Viagra and Cialis spam regained the top position, with Male Enhancement and various Pharmaceuticals filling positions 2 and 3. Diploma spam has almost doubled since last week and many spam templates are using URL shorteners to hide the destination.

For the last two weeks, Spammers have been using a new template that adds huge amounts of space-bar spaces between the spam words in the plain text source code. This is done to evade spam filters. This is followed by HTML content that is identical. However, when HTML is rendered, only one space is shown between words, making the actual spam message readable by a Humans. I have created and published new custom filters for MailWasher Pro users, which easily detect and block this type of spam, whether for diplomas or drugstores.

This past 7 days, spam for various types of unsolicited commercial email (UCE) amounted to 27% of my incoming email.

This week, my incoming spam level was just 1% lower than last week. However, the types of spam have begun to change in order of percentages by category. Some previously strong categories have dropped way down as spammers find them unprofitable.

Spammers are using a new template that adds huge amounts of spacebar spaces between the spam words in the plain text source code. This is followed by HTML content that is identical. However, when HTML is rendered, only one space is shown between words, making the actual spam message readable by a member of the Human Race. Writing a filter for this trick is trivial. I already have one for Diploma Spam using the multiple spaces and am in the process of creating another for pharmacy spam.

This week my spam percentage has increased slightly, to 29%, up 2% from last week. The subjects are exactly the same as they have been for the last year. Spammers are still pushing bogus male enhancement herbals, like the MaxGentleman, Chinese replica watches, counterfeit Cialis and Viagra, various illicit prescription pharmaceuticals, HCG weight loss scams, lottery and work at home scams.

Pharmaceutical spammers are still hosting their websites in Romania and are still using mostly .RU domains (Russian). All are advertising that they sell prescription drugs without the required prescription. Some are still falsely claiming to be "non-USA licensed pharmacies" - of which there is no such thing. The drugs they sell are counterfeit and both dangerous and unlawful to import into the USA or Canada.

This past 7 days, spam for various types of garbage amounted to 29% of my incoming email. This is according to MailWasher Pro, which I use to screen incoming email before downloading it to my desktop email program (Windows Live Mail).

This is my third article (see links at end) this calendar year about email archiving solutions for small and medium sized businesses. If you own or administer a business that uses email as an important tool for doing business, these articles will be of high importance to you and your IT staff. Today's article is about choosing the right email archiving software.

In today's business environment, email communication has become an essential tool, especially for small and medium-sized businesses. Laws and regulations related to the retention of email and other types of digital communication have increased, putting most businesses in a tough spot in which to balance their business needs and complying with on-going regulatory requirements. In addition, most small and medium-sized businesses do not have a robust IT department so having to worry about email storage issues, quota limits, eDiscovery laws, and other technical issues related to email takes time away from growing and expanding the business.

Email archiving can help with most of these issues if the right solution is used. As with any type of software, one size does not fit all. Be aware of your business IT environment and your business needs before searching for any email archiving solution.

Here are the features to look out for when searching for the right email archiving solution:

1. The ability to archive one or more databases: I would not want the archiving solution to archive emails to the mail server. This can cause performance issues and cause quota limit issues with the email server. There is no point in implementing something to solve one problem and to then cause another.


2. Users should have offline access to archived emails: Having a company's email archived but not easily accessible by users is a major drawback, and that is why a solid email archiving solution will provide access to email either through the email client or through web access. Users want to be able to access their archives if they are on the road, they have problems with their email client or only have basic web access. Providing offline access ensures continuity for the company and puts minds at rest that all their email, old or new is available with a few keystrokes.


3. Solve the issue with PST files: This type of offline access feature is usually a much better solution than using PST files which are difficult to manage and which put your email at risk as they can be lost once the PST is corrupted. Once you deploy an email archiving solution within the organization, you automatically eliminate the need to use PSTs - meaning goodbye to the headache of having to dig through a store of PSTs manually, goodbye to the risk of losing emails, goodbye the need to do PST backups; and hello to automatic email archiving in a central archive accessible to all which saves your admins priceless time, and the organization money.

Most email archiving solutions come with a variety of features. The ones mentioned here are only the highlights of such software. I would evaluate all email archiving solutions based, at least, on their ability to archive to a database and to allow users both online and offline access to their email archive.

This guest post was provided by Sean McCreary on behalf of GFI Software Ltd. GFI is a leading software developer that provides a single source for network administrators to address their network security, content security and messaging needs. More information: GFI email archiving.

It appears that my spam percentage has stabilized at about 27%, plus or minus a few points. The subjects are exactly the same as they have been for the last year. Spammers are still wasting their money spamvertising counterfeit Cialis and Viagra and pushing bogus male enhancement herbals, like the MaxGentleman aka Dr. Maxman and various illicit prescription pharmaceuticals without the required prescription. Knockoff Chinese watches, weight loss herbs, loansharks, and Nigerian advance fee fraud round out the field.

The majority of this week's pharmaceutical spam was for various incarnations of the fake "My Canadian Pharmacy," et al. The domains are all owned by Russians, using cheap domain Registrars in Russia, Czechoslovakia, and other parts of the former USSR, as well as some from a dis-accredited Registrar in Australia. Almost all of the current fake pharmacy domains use either Russian or Chinese Name Servers. At least half of the links in the spam messages for these pharmacies are to .RU (Russian) domain websites, many of which are now hosted by spam friendly hosting companies in Romania.

This past 7 days, spam for various types of garbage amounted to 27% of my incoming email. This is according to MailWasher Pro, which I use to screen incoming email before downloading it to my desktop email program (Windows Live Mail).

Prologue

Recently, I have published blog articles describing spam emails containing links to disreputable URLs. I have mentioned in these articles that one means of self defense against visiting obviously bad locations is to hover over a link and read the actual URL of that link - in your email client "Status bar." But, what if there is no Status bar showing in your email reader? How do you reveal it?

This brief technical article will show you how to show a hidden "Status Bar" on the most commonly email clients (in 2011). It also explains why having this bar visible is so important and a brief tutorial on making sense of the details that are displayed when one hovers over a link with their mouse pointer.

Displaying Email Client Status Bars

If you still have Windows XP (or, earlier; shudder the thought), you may have Microsoft's Outlook Express as your default POP3 email client. Others using XP, or Vista, have gotten the message about Outlook Express being deprecated (abandoned) by Microsoft and have moved up to Windows Live Mail (aka: WLM). People using Windows 7 are only offered Windows Live Mail 2011 (and newer, yet to come versions). All three versions have the means of turning the Status Bar on and off.

To show or hide the Status Bar in Outlook Express, Windows Mail (Vista only) and Windows Live Mail for XP and Vista, open the program, go to the menu bar item View, then click to place a check mark in Status Bar. It's that simple!

If you use Windows 7, your version of Windows Live Mail is probably version 2011 (or newer version, yet to come). Your interface is different than Outlook Express and the WLM for XP. To show the Status Bar, open the program, click on the "View" button in the row under the Title Bar, go to the right side and click the button labeled Status Bar. It appears (or disappears) instantly. Done!

If you are using Mozilla Thunderbird as your email client and for some reason the Status Bar is hidden, you can bring it back thusly: go to View > Toolbars > Status Bar and click to check it. The Status Bar will appear instantly.

Other email clients will have their own methods of turning the Status Bar on and off. I recommend leaving it on, all the time. Here's why...

Spam levels are continuing to decline, at least in my email accounts. This time last year, my percentage of spam email was 56%. This week, this year, it measured just 26%. That is a 54% decline in 12 months. The spam detected and deleted by MailWasher Pro was mostly for bogus male enhancement pills, which led by a 2:1 margin over other types of pharmaceutical and weight loss scams. Counterfeit watches and Nigerian lottery scams had measurable percentages.

I managed to trace several spam domains with the Russian .RU and some .COM TLD's to Romanian web hosts. Additionally, the SpyEye/Zeus Trojan Tracker, at Abuse.ch has traced down several SpyEye command and control servers to a Romanian hosting company. From Count Dracula to the Zeus and SpyEye Trojans, to fake pharmaceuticals and male enhancement scams, the Romanians have it all covered, with help from Russian Botmasters and master spammers. It is Russian and Romanian spammers who are paying to register and host hundreds of throwaway domain names, used in bot-sent spam blasts, promoting all manner of fake and illicit pharmaceuticals and herbals and exploits.

There was a measureable uptick in the amount of email containing direct links to exploit websites. My "Exploit Link" filter detected and deleted them all (see info on my custom MailWasher Pro filters, further down). Most led to the Zeus or SpyEye bank credential stealing Trojans.

Despite the fact that the volume and percentage of spam is declining right now, the threats contained in what is being sent are becoming more dangerous all the time. More and more spam is being sent after recipients identities are researched by spammers, who buy stolen IDs after break-ins of big company member databases. Others use password breakers to steal weak login credentials to free email systems, then send out spam targeting the entire contact list of the people who own those compromised email accounts. This happens constantly to Hotmail users.

You may have already received spam and scams targeting you by your personal or nickname. Therefore, effective email protection is required to protect your computers, your money and your data. MailWasher Pro is the program I use to detect and delete spam and email-borne security threats. My spam statistics are obtained from the program, showing how effective it is as a spam fighting tool.

This past 7 days, spam for various types of garbage amounted to 26% of my incoming email. This is according to MailWasher Pro, which I use to screen incoming email before downloading it to my desktop email program (Windows Live Mail).

This week's spam levels have remained at about the same level as last week. The majority of spammers are trying to sell counterfeit pharmaceuticals and replica watches, followed by weight loss herbs, male enhancement gimmicks, fake Viagra, and some Nigerian lottery and 419 scams. The various percentages of spam, by category, are listed in my extended comments.

This past week saw a continuation of the previously dead and buried Canadian Pharmacy scams. However, spammers are affiliates of various fake pharmacy programs. They pay Bot Masters to lease the use of zombie computers making up spam botnets. Spammers expect to be paid for the traffic they drive to the fake pharmacies. It so happens that the co-founder of one of the remaining major spam payment processors, Chronopay, has been arrested in Russia. Directly related to his arrest, several affiliate payment systems related to his RX-Promotions spam business are going offline (details to follow soon).

Canadian Pharmacy is one of the spam programs created, managed and paid for in Russia. I expect to see a big drop in all variations of Canadian Pharmacy spam, in the next week or so. No pay, no spam!

Despite fluctuations in volumes of junk email, spam is still going strong. It's not just nuisance messages you need to look out for. There are many critical security threats contained in attachments and links to exploit sites, which are designed to infect your computers with malware. Keyloggers, disguised as Flash upgrades, missing codecs, scanned documents, or resumes in attachments, silently log your keystrokes when you log into your online bank, or PayPal, or your website control panel, stealing your credentials, then you money or company secrets. Therefore, effective email protection is required to protect your computers, your money and your data. MailWasher Pro is the program I use to detect and delete spam and email-borne security threats. My spam statistics are obtained from the program, showing how effective it is as a spam fighting tool.

On June 15, 2011, I wrote a blog article about the re-emergence of the previously killed off Canadian Pharmacy scams. When I published that article I also filed a spam report against the domain named used in the link in the spam email I received, with their Registrar of record. Two days later the domain was suspended for violating the Registrar's terms of service.

Tonight I received two more identical spam emails, with two different domains in the links, promoting a Canadian Pharmacy selling the same Anti-ED drugs. I have filed a report with the Registrar of record, nameregistrars.net, for the first one: eumbyhojbu.com. The second domain link was for: gffbn.ru. This is a Russian domain. The only information I can find on it is that it leads to the same IP address as the previous two spam links did. All of these fake Canadian-Pharmacy/My Canadian Pharmacy links are redirected to a rogue pharmacy website hosted on a Romanian PC or server (at 194.50.7.208), running a Russian Nginx web server.

Notably, all of these spam emails use hidden ISO codes in the From and Subject fields to evade spam filters. Your email client is happy to translate them into the names of the pharmacy and illicit drugs they are selling.

As was the case with the previous fake pharmacy landing page, this one uses a variety of Chinese and other Botnet sources to assemble the images used to fool people into believing it is a legit pharmacy. It is all snake oil and octopus juice. This is a fake pharmacy, hosted in Romania, using Russian Name Servers. The PCs used to deliver the spam emails for it are part of a world-wide spam botnet.

Do not believe anything found in the emails promoting these fake Canadian Pharmacy websites. Never buy anything from those sites. You will be handing over your credit or debit card details to Russian spammers and criminals. If you ever receive the illegal drugs you ordered, they will be counterfeit, made in Asia. They may harm or kill you. If you are lucky, you'll never receive them at all. Better to be out a few hundred bucks than pushing up daisies from OD-ing on fake Viagra laced with Melamine!

This article, short as it may be, could save both your money and identity, if you are a PayPal customer.

PayPal, now an eBay owned company, manages the money for all transactions conducted on eBay, plus those of a huge number of non-eBay customers who use PayPal to send and receive money online. In all, as of June 2011, PayPal claims to have 98 million active users, in 190 different markets and 25 currencies. You may be one of those members.

If you are not a PayPal member and do not make any purchases on eBay, nor send donations via PayPal Donate buttons, or make any other payments through them, you will automatically treat all email claiming to come from PayPal as spam and a probable Phishing scam (most are). You won't be tempted to click on any links to login to your PayPal account if you don't have one!

But, if you are one of the 98 million members of PayPal, whether you use them rarely, or often, you have to allow them to send you email messages. It is not optional. This leads me into the topic at hand:

PayPal is still sending official email messages to its members, containing clickable links, and urging you to login to your account via those links.

This is exactly the same behavior used by Phishing scam artists. They send official looking copies of the exact emails that companies like PayPal are sending to their customers. They include clickable logos and text links, urging you to use them to login to your PayPal account and give away your username and password and all of your money that is either in your PayPal account, or in the credit card linked to it, or in the bank account linked to it.

In the case of actual PayPal email messages, the only obvious distinction is that they always address you by your proper name, as it is registered with them (E.g.: Dear Joe Blow). The Phishing scams usually address you as "Dear Member." The actual difference in the links is that the real PayPal email links point to sub-domains on paypal.com, like: email0.paypal.com/servelet/whatever... whereas the links in Phishing emails will lead to a different domain than paypal.com.

You can learn to see the actual location of any link in most email messages by hovering your mouse or pointer over the links, but not clicking on them. The actual domain portion comes between the http:// and the first forward slash (/). Any domain names that follow the first forward slash are inserted to fool you. So, if the URL you see in the Status Bar show something like this: https://email0.paypal.com/servlet/cc6?iitgHQYRASQUV... it is an authentic PayPal link. On the other hand, if the hover link resembles this: http://account-verify-paypal.com/... it is a fake. The domain in the second link leads to a domain named account-verify-paypal.com - which is NOT the same domain as paypal.com! But, https://email0.paypal.com/ IS a sub-domain on paypal.com.

Sub-domains are separated from the master domain by a period (.); not a dash (-), nor an underscore (_). Only a DOT between the first name and the domain name is a legal sub-domain. Thus, this is a sub-domain: email0.paypal.com/ ... This is NOT a sub-domain: email0-paypal.com; it is a totally different Domain Name.

This information about hovering is fine for people using a standalone email program, like Microsoft Windows Live Mail, or the old Outlook Express, which display a Status Bar on the bottom by default. But, many people use their web browsers to do email and quite a few do not opt to display the Status Bar. Those folks will not see the true destination of links before they click on them.

It it a foolish act, in many opinions, for a huge financial firm, like PayPal, to send out email communications about Policy Updates, overdrafts, pending cases, etc, and include clickable links to log you into your account! This is the very same means used by fraudsters to trick victims into clicking on their links to look-alike login pages, where your credentials and money and bank details will be stolen.

PayPal would better serve all of its customers by instructing them to login to PayPal (or their bank) by typing in the URL, in the browser address bar, or by re-using a link they saved from a previous, legitimate online session. Most browsers save your frequently visited websites and will help you as you type. I opnly need to type a couple of characters for the legitimate PayPal URL to appear.

Note: All PayPal logins should have HTTPS at the beginning of the URL; NOT HTTP. HTTPS indicates a secure connection, to a website with a legitimate safety certificate issued by a secure (SSL) license issuer. Anything you type into input fields in an HTTPS connection is encrypted before being sent out from the browser. Anything typed into a form on an HTTP page is sent out in plain text.

The bottom line and message I am trying to impart to you is this: It makes no never mind what the links in a PayPal email (real or fake) lead to. DON'T USE THEM! They might be real, or fake and you may not be able to tell from how they are displayed in your Status Bar (if you have one showing). If an email arrives from PayPal, about an important matter, like their Policy Updates, or Disputes, or accounts added, ignore the links in the message. PERIOD. Go to your browser, open a new tab, or new window and type in https://www.paypal.com/ then make sure it still says exactly that in the location/address bar (watch out for typos that could lead to malware sites), then press Enter. Then and only then, type in your login credentials.

By always typing in the address of important financial websites, then verifying them before pressing the Go button, or Enter, you can hopefully avoid being phished by credential crooks. There are other ways they can ensnare you, so keep your computers protected with the best anti-malware program you can afford. I use and recommend Malwarebytes' Anti-Malware and also, Trend Micro Titanium Internet Security Pro

After decreasing last week, this week's spam levels have remained at the same level. The majority of spammers are trying to sell counterfeit replica watches, followed by illicit prescription pharmaceuticals (sans the req'd prescription), male enhancement herbs, fake Viagra, weight loss drugs and even some Nigerian 419 scams. The various percentages of spam, by category, are listed in my extended comments.

This past week saw a return of the previously dead and buried Canadian Pharmacy scams. This time, the spam sender uses the name "Canadian-Pharmacy" and the faked destination website says "My Canadian Pharmacy." Other than the addition of "My," the rest is identical to the old websites. They are still hosted on botted PCs, controlled by Russian spam gangs and Bot Masters. The landing pages include logos with links to alleged Accreditation sources, all of which all go right back to the same fraudulent web page, on the botted PC. I wrote a full analysis of this new Canadian Pharmacy scam in a recent article.

Despite fluctuations in volumes of junk email, spam is still going strong. It's not just nuisance messages you need to look out for. There are many critical security threats contained in attachments and links to exploit sites, which are designed to infect your computers with malware. Keyloggers, disguised as Flash upgrades, missing codecs, scanned documents, or resumes in attachments, silently log your keystrokes when you log into your online bank, or PayPal, or your website control panel, stealing your credentials, then you money or company secrets. Therefore, effective email protection is required to protect your computers, your money and your data. MailWasher Pro is the program I use to detect and delete spam and email-borne security threats. My spam statistics are obtained from the program, showing how effective it is as a spam fighting tool.

This past 7 days, spam for various types of garbage amounted to 26% of my incoming email. This is according to MailWasher Pro, which I use to screen incoming email before downloading it to my desktop email program (Windows Live Mail). I report any spam messages that make it through my auto-delete filters to SpamCop.

Here are some statistics regarding the spam received and categorized, from June 12-19, 2011. These classifications are based upon my own custom MailWasher spam filters. Most of this spam is automatically deleted by MailWasher Pro and my custom filters. The statistics are obtained from the program's logs.

Statistics Overview

Percentage classified as spam:26%; 0% from last week
Number of messages classified as spam: 112
Number classified by my custom spam filters: 101
Number and percentage of spam according to my custom blacklist: 2
Number classified as spam by the Bayesian Learning filter: 0

After an increase last week, this week's spam levels have decreased again. This yo-yo effect is possibly due to problems Bot Masters are having maintaining their spam botnets, in the face of strong pressure from Microsoft, the DOJ, FireEye and cooperation from law enforcement authorities in Russia. The various percentages of spam, by category, are listed in my extended comments.

Bot Masters, who send the orders and templates to the zombie spambots (robot agents on infected personal computers), depend on professional or newly recruited spammers to pay to rent the use of their botnets. Competition among botnet owners, dis-infection of botted PCs and interference from authorities tends to drive prices down for some services and up for others. These days, there seems to be more money to be made by renting out botnets for use in denial of service attacks, than for sending e-junk mail.

Despite fluctuations in volumes of junk email, spam is still going strong. It's not just nuisance messages you need to look out for. There are many critical security threats contained in attachments and links to exploit sites, which are designed to infect your computers with malware. Keyloggers, disguised as Flash upgrades, missing codecs, scanned documents, or resumes in attachments, silently log your keystrokes when you log into your online bank, or PayPal, or your website control panel, stealing your credentials, then you money or company secrets.

After two weeks in a row of reduced spam volumes, spam levels have increased again, as anticipated. Spam for imitation Viagra lead counterfeit watches by a ~5% margin. This was followed by weight loss scams promoting the illegal sale of the controlled Schedule 4 drug: Phentermine. Spam for various pharmaceuticals and male enhancement scams had lower proportions than usual. I saw a lot of what appears to be French language spam, which I can't read, followed by fake Adobe and Skype upgrade exploit links and work at home scams.

Spam is still with us, along with security threats contained in scams and exploit email links, so, email protection is still needed as it will get worse again (it always ebbs and flows). MailWasher Pro is the program I use to detect and delete spam. My spam statistics are obtained from the program, showing how effective it is as a spam fighting tool.

During the past week I have been receiving, classifying, reporting and deleting scam emails pushing links to fake upgrades for Adobe, Skype and the now defunct LimeWire programs. The bulk of these arrived over the past 24 hours, right up until a short time before I wrote this article. You need to be aware of the nature of these scams and make sure you don't fall for them.

Let's start with the most prevalent of the new scams: the fake Adobe Reader upgrade notices. It starts with the arrival of unexpected email messages spoofing that they were sent from Adobe Support. The subjects contain wording such as: "New Acrobat PDF Reader Has Released !" - followed by either Download or Upgrade Now. While the From field contains a plain text name that includes Adobe Support, or email.adobe.com, in the Prefix, it does not have an Adobe domain in the actual sender's email address. Rather, one may find, as I did, that they are spoofing the sender as an account at "hotels.octopustravel.com."

The message body includes an introduction in all capital letters (as of this writing), claiming: "ADOBE PDF READER UPGRADE NOTIFICATION" - followed by descriptive text copied from the Adobe Reader web pages. The scammers then announce: "contains critical security updates" and provide you with a cleverly worded link that includes the words "adobe", "PDF" and/or "Reader", with dashes between words, ending with the word -download(s) or -upgrade,com. The links are leading to exploit websites in China, hosted on Windows servers at: 122.224.4.113, and possibly other nearby IP addresses.

The related Skype scams purport to come from Skype Support (but not from skype.com) and tell about all of the benefits of upgrading to the newest version of Skype. However, as in the previous Adobe scam, the links end in -download(s).com. Again, this domain is hosted on a Windows IIS web server in China, at 122.224.4.113 (or neighbors).

The latest round to arrive this evening claim to lead to an alternative to the now defunct LimeWire file sharing system. That illegal file sharing service was shut down by US Federal Court action, led by the D.O.J. The new scam claims to offer you free P2P software that allows you to send and receive illegal files with other law breakers and pirates. However, if you download that installer, instead of getting connected to a new file sharing service, you will become botted, with your PC becoming a contributing member of a peer to peer spam botnet. Then your PC will be used to send out messages like these to innocent people whose email addresses have been harvested by spam bots on their friends computers.

I have just finished writing three new filters for MailWasher Pro users, which detect these new software scams and block them (with either automatic or manual deletion). All of my custom spam filters are available in both the old (filters.txt - for up to v 6.5.4) and new (Filters.xml - for MWP 2010 onward) MailWasher formats. If you use MailWasher Pro to filter out spam, before downloading it to your desktop email client, you should take a look at my filters and see if they help reduce your time spent classifying what is good and what is spam email.

My filters are still free to download and use, but I most certainly do appreciate any donations that grateful MailWasher Pro users make, to show their appreciation for my work.

For two weeks in a row, spam levels have remained lower than usual. Spam for counterfeit watches maintained its lead over imitation Viagra and Cialis, by a ~9% margin. This was followed by the return of weight loss scams, male enhancement scams and various dating and lottery scams and links to .RU domains, all of which had lesser percentages.

The malware in attachments, for botnet installers,reappeared this week, in the form of fake links to Adobe Reader and Skype updates. I pity anybody who was fooled into clicking on those hostile links (they are now botted!). When the botnets lose zombie members from disinfection, their Bot Masters send out new rounds of malware infected attachments and links, to rebuild their armies of spam-bots.

To a medium or large business, email correspondence is not something taken lightly or casually deleted after being read. In fact, most serious businesses keep all email for future reference, in the event of disputes, lawsuits, law enforcement subpoenas, to find customer registrations when customers lose their registration codes, to have a record of interchanges between customers and support staff, etc.

The safe storage of read email requires some forethought. Disasters can and do happen, affecting workstation computers, file servers, in-house mail servers and buildings housing the infrastructure. To safely keep thousands of important email messages from harms way, and in some cases to comply with Government regulations, companies are looking for safe storage and archiving solutions. This article gives you some insight into some options you should consider, if you are tasked with finding an email archiving solution for your company.


The process to deploy an email archiving solution can be broken down into concise steps, for both cloud-based offerings and in-house solutions. Below are some of these steps:

1. Meet with your stakeholders
   Email archiving solutions should help you meet legal, regulatory, and HR requirements; information security concerns; and likely existing document retention policies.
   


2. Estimate the size of the solution
   An in-house solution's most significant factor will be the amount of disk space required to store the archives. An outsourced solution's most significant factor will be the number of users. Estimate both, based on current sizes, projected growth of the company, and the feedback from the stakeholders regarding the length of time messages must be stored. I like to take this number and apply the Pi factor to it, which means I multiply the result by 3.14 to account for unanticipated growth. Use this to estimate the costs for your solution and include it in #3 below.
   


3. Determine whether you will deploy an in-house or cloud-based solution
   While most companies maintain email archives on-premises, some SMEs are looking at outsourcing as an attractive alternative. Cloud-based solutions are good for meeting e-discovery purposes. For those who want a more full-rounded solution that helps them not only meet legal requirements but also offload Exchange and get rid of PST files, than on-premise is the way to go. Others may prefer a combination of both on-premise and on-line, enabling them to split the archive for rarely accessed email (on-line) and current content (on-premise).
   


4. Plan for client deployment
   Some solutions require an agent to be installed on the client, and almost all companies will need to address the PST files that are no doubt scattered all over home drives, local disks in the case of laptops, and may even be on personal external storage. One benefit of an email archiving solution is that it reduces the need for PST files, and many archiving solutions include automatic imports of PSTs to the archive to ensure data is preserved and available. Better solutions enable users to search the archives and restore the email they may have deleted from their mailbox, so decide whether to use a portal, an Outlook plug-in, or both.
   


5. Pilot the solution
   Once you have chosen your solution, start by archiving a pilot group of users. Solicit regular feedback from these users on performance, ease of use, and their experiences with searches, restoring deleted emails, etc. Use their feedback to tune the system and to develop any training or informational materials for sharing with the rest of the company.
   


6. Deploy the solution to all users
   Once the pilot users have signed off on the system, deploy to the rest of the company. Monitor for the increase in Internet bandwidth if you deployed a cloud solution, or with disk i/o if you went with an in-house option, to ensure that the system is performing well.
   

Following these six steps will help to ensure a successful deployment of your email archiving solution, whether it is an in-house or outsourced solution. By including input from key stakeholders, getting feedback from your test users, and testing the solution with your existing systems, you will find email archiving to be a great addition to your email infrastructure.

The reduction in last week's spam levels might have been due to spammers holding back, or Bot Masters laying low, to try to avoid the authorities who are trying to track them down and shutter their operations.

Following three weeks with little change in my level of spam, this week's levels have increased slightly. Spam for counterfeit watches led the pack by a 7% margin. This was followed by various illicit pharmaceuticals, counterfeit Viagra-Cialis, and male enhancement scams. Various scams and malware in attachments had lesser percentages.

Spammers depend on the cheap use of millions of infected PCs that have been involuntarily made zombies in spam botnets. As authorities shutdown one botnet another rises to claim their share of the spam pie. As the number of infected machines declines, due to the owners being made aware of their problem and disinfecting their computers, the bot herders use whatever means is available to them to regain zombies in their herds. Sending fake delivery notices with bot installers is one of the favorites of malware distributors.

Following two weeks with no change in my level of spam, this week's levels have declined significantly. Spam for counterfeit watches led the pack by a 10% margin. This was followed by counterfeit Viagra-Cialis, various illicit pharmaceuticals, and male enhancement scams. The Nigerian 419 scammers and Russian bride scams had a measurable percentage this past week.

Spammers depend on the cheap use of millions of infected PCs that have been involuntarily made zombies in spam botnets. As authorities shutdown one botnet another rises to claim their share of the spam pie. As the number of infected machines declines, due to the owners being made aware of their problem and disinfecting their computers, the bot herders use whatever means is available to them to regain zombies in their herds. Sending fake delivery notices with bot installers is one of the favorites of malware distributors.

You still need spam protection and it is showing signs of getting worse again. MailWasher Pro is the program I use to detect and delete spam. My spam statistics are obtained from the program, showing how effective it is as a spam fighting tool.

This past 7 days, spam for various types of garbage amounted to 31% of my incoming email. This is according to MailWasher Pro, which I use to screen incoming email before downloading it to my desktop email program (Windows Live Mail). I report any spam messages that make it through my auto-delete filters to SpamCop.

Here are some statistics regarding the spam received and categorized, from April 18 - 24, 2011. These classifications are based upon my own custom MailWasher spam filters. Most of this spam is automatically deleted by MailWasher Pro and my custom filters. The statistics are obtained from the program's logs.

Following last week's slight drop in spam, this week's levels increased by 6% (of my incoming email). Spam for counterfeit watches led the pack by a 19% margin. This was followed by pharmaceuticals of the usual type. Also, there was a noticeable barrage of malware infected spam claiming to come from Express Services and Postal Express. I hope that none of my readers were curious enough to open one of the attachments from these fake courier scams. If you did, your PC is now probably a member of a botnet.

Following last week's big increase in spam, this week's levels dropped slightly, by 3% (of my incoming email).

After briefly rising last week, spam levels have fallen again, following this week's takedown of the Rustock spam botnet's command and control servers, by Microsoft, Pfizer, Fire-eye and the US Marshall's Service. My statistics reveal a 7% decrease from the previous week. Prior to the shutdown of those servers, Rustock was responsible for over 40% of the world-wide spam.

Immediately following Rustock's takedown, on March 16, there was a big drop in spam. However, other botnets quickly rented out their services to spammers, so the amount of spam rebounded over the last few days to regain several percentage points. You can look for those botnets to become the next targets of Microsoft, Pfizer and other anti-spam agencies.

Pfizer was involved because so much spam is for counterfeit Viagra, which is a trademarked and controlled drug manufactured and distributed by Pfizer and it's legitimate partners. They do not license Russian, Indian, or Chinese based Internet pharmacies to make or distribute Viagra, or to use the trademarked name of the company or the drug. Anybody offering to sell Viagra (real or counterfeit) to US residents, without a valid prescription issued by a real US based and licensed doctor, after an actual physical examination, is violating US Federal law. Anybody attempting to purchase Viagra, or other controlled prescription drugs, from an Internet pharmacy located outside the USA, or any Internet pharmacy that sells pharmaceuticals that are not manufactured or licensed for sale in the USA, is guilty of violating US laws regulating the purchase of controlled substances. Those purchases are subject to seizure by US Customs and smuggling charges can be filed by Federal authorities.

This past 7 days, spam for various types of garbage amounted to 28% of my incoming email. This is according to MailWasher Pro, which I use to screen incoming email before downloading it to my desktop email program (Windows Live Mail). I report any spam messages that make it through my auto-delete filters to SpamCop.

Every weekend I write an article about my spam analysis for that week. This often includes details about phishing scams that target individuals and company employees, for the purpose of stealing your identity, logins and passwords to important web sites, private or company information, or trade secrets.

The following is a guest article sent to me by GFI Software, a leading software developer that produces network and email/messaging security solutions for SMEs. GFI is also the owner of Vipre Antivirus. This article deals with protecting your employees from falling victim to phishing scams that arrive via email.

Data, the lifeblood of every organization, is also a magnet for phishing emails and other social engineering scams. Phishing scams come in a variety of flavors but predominately are pushed through email or, recently on the increase, through social networking sites and Instant Messaging. In essence these carefully crafted emails, appearing totally legitimate, aim to trick unsuspecting employees in giving up personal or financial information which the phisher, in turn, uses to commit fraud and for personal gain.

Understanding how to identify phishing emails and scams is important because it will lead to better management of the problem and afford better protection for your network and data (before your employees thoughtlessly click on them). Below are some points to keep in mind:

1. Do not trust emails with urgent requests for personal or financial information. Such emails are often near-genuine messages from banks, credit agencies, official government bodies and online vendor or payment sites. They also tend to come with a lot of dire 'warnings' -deliberately attempting to scare the recipients and force them to click on links and give out details before they have time to properly assess the veracity of the claim. Keep in mind that the legitimate senders usually rely on other means to contact you, rather than through email. If you have any doubts about the content in, or the sender of, the email, pick up the phone and speak to them directly. Better safe than sorry.


2. Look out for misspelled URLs and incorrect English - A classic in phishing emails. They are great in tricking people but they are not always drafted by good writers. The content is usually peppered with grammatical areas. Phishers also make subtle changes to the spelling of website URL, for example: http://www.christinsblog.com instead of http://www.christinasblog.com. Look out for these errors.


3. When receiving an email which addresses you as 'Dear customer', rather than by your first and/or last name, it is probably a scam.


4. Look out for keywords, such as: 'verify your account' or 'verify your ID' - these are usually found in phishing emails.


5. Always be suspicious of emails which ask you to click on links. Unless you are sure that the sender is legitimate, never click on links in emails.

Emails are a significant part of a business's records, and need to be stored to meet organizational needs as well as legal and compliance requirements. How this is done can make an incredible difference to the lives of both end-users and administrators.

Is your organization archiving email the right way?

An Exchange or email server may easily be brought down when its mailboxes contain too many large email attachments or when there are large numbers of email accounts. System administrators usually solve this by putting a quota on each mailbox so as to limit the amount of information stored on the server while moving older emails to a different location so as not to surpass this limit. This can irritate or frustrate end-users, especially when they need to retrieve emails that date back to many years before. In order to save these emails and respect the quota simultaneously, some end-users store their email in PST files (open proprietary file formats that are used for storing copies of messages) which they either save on their local machine or on a network share. If this sounds like the system in place at your organization, steady yourself: You might be in for a few problems.

When stored locally, PST files cannot be backed up regularly. This means that if one of them is damaged or accidentally deleted, the emails within it are lost. On the other hand, when end-users store their PST files on a network share, this simply transfers the whole issue of storage space from one location (the server) to another (the network share), while also presenting the need to increase the number of backups coupled with the ordeal of having to manage all those PST files - a pet hate for many administrators.

How to tackle this storage problem

With Christmas arriving this coming weekend, spammers have ramped up their efforts into overdrive, in order to divert some of your hard earned dollars into their purloined pockets. Don't be fooled by their email pitches. Spam offers are fraudulent, dealing in fake goods and payment ripoffs.

Take my advice and never reply to spam email, just delete it. Don't bother trying to unsubscribe from spam mail lists. Nobody ever gets de-listed; you will only confirm that your email address is valid by using the bogus unsubscribe links. Think about it: if you never signed up to receive the (fake) goods advertised in a spam email, why should you have to unsubscribe? The unsubscribe links are not honored. However, people using them are added to databases of proven live accounts and their names are sold to other spammers.

Spammers are slimeball criminals and fraudsters, not legitimate business people. Never buy anything that is spamvertised. If you do, you will give your credit or debit card details to hardened criminals, in far away places. If you purchase illicit controlled drugs from abroad, they are subject to seizure by US Customs. It is against the law to import prescription drugs without a valid prescription issued by a physician who is validly licensed in the USA. And, if you actually receive Asian prescription pills ordered from a spam email link, the drugs may do nothing, or may harm you, or even kill you.

A word regarding knockoff watches: they are made in China, have no applicable warranty, cannot be returned if defective, are sold by criminal spammers, and are inferior to the real items they are copying. If you buy a counterfeit name brand watch, know that a fool and his money soon will part! Ditto for fake diplomas that are offered from time to time and all of the fake Viagra pills and enlargement scams that appear every day.

With Christmas around the corner, spammers are ramping up their efforts to get some of your hard earned dollars and infect more machines, for use in Botnets. There is a virtual flood of crap mail deluging email inboxes this week, mostly hawking things like fake Viagra, counterfeit watches and designer bags and jewelry, illegal to import prescription drugs, bogus male enlargement herbs and pills, the tail end of a Pump and Dump penny stock scam (DYNV) scam and a handful of work at home money laundering scams (money mule recruiters for bank account stealing Trojans, like Zeus and similar info stealing Bots). There were a few phishing scams thrown into the mix, earlier in the week.

This past 7 days, spam for various types of garbage amounted to 51% of my incoming email. This is according to MailWasher Pro, which I use to screen incoming email before downloading it to my desktop email program (Windows Live Mail). I often see the same spam message sent to several of my accounts at the same time. I report any spam messages that make it through my auto-delete filters to SpamCop.

Here are some statistics regarding the spam received and categorized, from December 6 - 12, 2010. These classifications are based upon my own custom MailWasher spam filters.

Percentage classified as spam: 51%; down 5% from last week
Number of messages classified as spam: 370 
Number classified by my custom spam filters: 353
Number and percentage of spam according to my custom blacklist: 15
Number classified as spam according to DNS Blocklists (SpamCop, Spamhaus, etc): 2
Number of spam messages seen, reported to SpamCop & manually deleted: 39

Fake Viagra and Cialis: 37.30%
Counterfeit (Rolex, etc) Watches: 14.05%
Pharmaceuticals and fake prescription drugs: 13.24%
Male Enhancement scams: 7.30%
Other miscellaneous filters (small percentages each): 6.22%
Known Spam Domains in links (usually Russian: .RU): 5.68%
Counterfeit Goods: 5.41%
Blacklisted sender names and domains: 4.05%
Charset=iso-8859-2 (Latvia, etc): 2.16%
Numeric IP hostile link (hijacked PCs): 1.62%
Russian Sender: 1.35%
Work At Home Scams (money laundering stolen funds): 1.08%
DNS Blacklisted Servers: 00.54%

I made 1 additions/updates to my custom filters:
Counterfeit Goods

I made no changes to my custom Blacklist:

Take my advice and never reply to spam email, just delete it. Never buy anything that is spamvertised. If you do, you will give your credit or debit card details to hardened criminals, in far away places. If you purchase illicit controlled drugs from abroad, they are subject to seizure by US Customs. It is against the law to import prescription drugs without a valid prescription issued by a physician who is validly licensed in the USA.

A word regarding knockoff watches: they are made in China, have no applicable warranty, cannot be returned if defective, are sold by criminal spammers, and are inferior to the real items they are copying. If you buy a counterfeit name brand watch, know that a fool and his money soon will part! Ditto for fake diplomas that are offered from time to time.

Look out Christmas shoppers! Spammers are ramping up their efforts to get some of your hard earned dollars. There is a virtual flood of crap mail deluging email inboxes this week, mostly hawking things like fake Viagra, counterfeit watches, illegal to import prescription drugs, bogus male enlargement herbs and pills, Russian dating and "chat" scams and work at home money laundering scams (money mule recruiters for bank account stealing Trojans, like Zeus/Licat and similar Bots).

Note: if you fall for a money mule recruiter scam (work at home and make $$$ per day/week) and become involved in transferring stolen funds overseas, you could go to jail for being an active accomplice in a money laundering scheme (of money stolen from bank accounts by hidden keystroke logging Bots). Always use the best anti-malware protection you can afford, like Trend Micro Titanium Internet Security and Malwarebytes' Anti-Malware (MBAM). These two commercial programs can detect, remove and block most badware being released on a daily basis. If you run MBAM as freeware, make sure you update it before scanning, and scan every day!

This past 7 days, spam for various types of garbage amounted to 56% of my incoming email. This is according to MailWasher Pro, which I use to screen incoming email before downloading it to my desktop email program (Windows Live Mail). I often see the same spam message sent to several of my accounts at the same time. I report any spam messages that make it through my auto-delete filters to SpamCop.

Number classified by my custom spam filters: 419
Number and percentage of spam according to my custom blacklist: 23
Number classified as spam according to DNS Blocklists (SpamCop, Spamhaus, etc): 5
Number of spam messages seen, reported to SpamCop & manually deleted: 30

I made 5 additions/updates to my custom filters:
APNIC (China, etc)
Dating Scams
Male Enhancement scams
Watches (fake, counterfeit Rolex, etc)
Work At Home Scams ("money mule" recruiters)

I made these changes to my custom Blacklist:
shopathome@shopathomenews.com (fails to honor repeated unsubscribe requests!)

Take my advice and never reply to spam email, just delete it. Never buy anything that is spamvertised. If you do, you will give your credit or debit card details to hardened criminals, in far away places. If you purchase illicit controlled drugs from abroad, they are subject to seizure by US Customs. It is against the law to import prescription drugs without a valid prescription issued by a physician who is validly licensed in the USA. Finally, there is no actual Canadian Pharmacy. If you see email purporting to come from Canadian Pharmacy, or any variation of those words, delete it. The non-existent company was conceived by Russian spammers. Any drugs actually shipped come from illicit pharmaceutical knockoff factories in Asia.

This is the latest entry in my weekly series about classifications of spam, according to my custom filter rules used by MailWasher Pro. The categories are shown on the "Statistics" page > "Junk Mail," as a pie chart, based on my custom filters and blacklist. The amount of email flagged as spam is shown on the "Summary" page of Statistics. These reports can help you adjust the order of your own spam filters.

MailWasher Pro is a POP3 and IMAP email spam screener that checks email before it is downloaded to your desktop email client. It can be set to delete recognized spam either manually or automatically when a user-defined filter, or the built-in learning filter, or a blacklist entry, or known spam source is matched, or an attached virus is detected.

My incoming spam levels have decreased 5% this week, to 48% of all my incoming email. Most of the spam was typical junkmail for counterfeit Chinese watches, fake Cialis and Viagra, illicit prescription drugs and male enhancement scams. There was also a new type of spam in the wild, with the subject "hello" and the body text: "How are you?" I'm not sure if this was a dry run for a spam blast, or if the reply to addresses are being monitored by Botmasters, or spammers.

The classifications of spam in my analysis (below) can help you adjust your email filters according to what is most common, on a weekly basis. If you are using my custom MailWasher Pro filters, keep the filters for the highest percentage categories of spam near the top of the filters list, to minimize the impact on your CPU when analyzing incoming messages for spam content.

Since virtually all spam is now sent from and hosted on hijacked PCs that are zombie members of various spam Botnets and all email sender addresses are forged, there is no point in complaining to the listed From or Reply To address. These accounts are inserted by the same script that composes the spam on the compromised PCs. These are innocent spam victims themselves, whose harvested names are reused in forged From addresses.

Sometimes, your own email address is forged as the sender, as well as being the recipient. The practice of forging the recipient's own email address in the From field is known as a "Joe Job." Fortunately, MailWasher Pro has a custom filter option that overrides the "Friends" list (a Whitelist of approved senders), allowing user created spam filters to read the content and flag or auto delete spam that's using one's own accounts as the forged sender.

You can take preventative measures to secure your computers from becoming members of Botnets, by installing Trend Micro Internet Security and MalwareBytes Anti-Malware (see pages for details).

For a couple of days I have been seeing a new round of nasty Trojan attachments in emails posing as FedEx invoices. This scam is not new. It has been ongoing for months now. The payload, in an attached zipfile, has been either the Bredolab or Zeus Trojan in the recent past. The Bredolab makes a PC a member of a spam and DDoS Botnet. The Zeus (Zbot) plants and info stealing keylogger on your system, then protects it wilh a rootkit. The Zeus monitors logins to a long list of popular banks, payment processors and online game sites, then captures the key strokes as you log in, and soon, most of your money is gone to Russia.

Although the scam is not new, the method of delivering the convincing con has changed. This week has seen the arrival of the con being embedded in an inline image, in the .jpg format. The message I am looking at right now has the following text embedded as its content:

"Dear,
Unfortunately we failed to deliver the postal package you sent on the 27th of July in time because the recipient's address is erroneous. Please print out the invoice copy attached and collect the package at our office."

The message then screws its own pooch by displaying this odd text: "'Spiderman' climbs again in Sydney ." However, I'm sure that will disappear, as spam filters around the world tune in to that phrase.

The attachment, which claims to be a FedEx document (invoice) is inside a .zip file and is in fact a very dangerous Trojan. If you open the zip file and launch the embedded executable, your PC will become a zombie member of a spam and attack Botnet, and or will have the Zeus Trojan installed, to steal your logins and money.

If you may have already fallen for this scam, please scan your computer with the Trend Micro online Housecall malware scanner. Then, if at all possible, update your existing anti-virus program and scan with it. If your anti-virus is old and the subscription is expired, download a free, fully functional trial of Trend Micro Internet Security. Install it, update it, then scan the entire computer.

Further, I recommend downloading and installing/scanning with Malwarebytes Anti-malware (MBAM). Both of these security applications will detect the threats contained in the fake FedEx scams attachments and will halt their hidden processes and delete their files. You will have to restart the PC and scan again and may have to disable System Restore. Many types of malware hide as backups in the hidden system restore folder and are restored after you clean the machine, then reboot. Turning off System Restore kills the malware backups. Don't forget to turn it back on after cleaning has completed!

If the malware prevents you from updating, or installing, or running a real security program, go to Bleeping Computers malware removal forum, sign up for an account, read the instructions, then open a new topic requesting personal help. A trained, volunteer malware removal expert will assist you as soon as he or she is able to. They will recommend free tools you can use to restore your PC to normal working condition. Read every word carefully and only do what you are asked to do.

Malwarebytes also has an expert malware removal assistance forum. Their forums are meant for people attempting to use MBAM to remove malware.

Both of the aforementioned programs will protect you from getting infected in the first place! Trend Micro Internet Security not only has regularly updated onboard malware definitions and behavioral analysis engines, but also consults a definitions server referred to as a "Cloud Server." As new releases of malware are captured (by security company honeypots), they are rapidly examined and new definitions are published to the Cloud servers, before they are pushed to client computers. Further, the destination websites are instantly blocked by the "Trend Micro Smart Protection Network." All subscribers to Trend Micro security programs are instantly protected from visiting those hostile websites and servers. You can learn more, download and purchase a subscription here.

Malwarebytes Anti-Malware is free to use in purely manual mode, but this won't protect you against reinfection. You can get realtime protection and automatic updating and scanning by paying $24.95 US dollars or equivalent in your currency, for a lifetime license. Read the details and download or purchase a license for MBAM here.

In early July, 2010, Firetrust, the makers of the famous anti-spam program: MailWasher Pro, released a brand new version. The new MailWasher 2010 was several years in the making and touts a new user interface, new spam weighting system and a brand new spam filter format.

Previously, MailWasher spam filters were in a plain text file, aptly named "filters.txt" - with each filter on a long separate line, ending with a line feed, but no blank lines between them. Some filters have many individual rules and trying to read and debug them is a challenge. The new version uses a well formed XML format, with indented sections and rules. This is a visually pleasing layout that is easy to read and edit, rule by rule. However, because each rule and condition is on a separate line, the file size is much larger than the old flat text file filters.

As many of you know, I write and publish spam filters for use in MailWasher Pro. I have been writing and updating these filters for years. But, with the release of the new MailWasher 2010, a lot of work was needed to convert the old filter format into the new one. The good news is that as of today, August 22, 2010, I completed the conversion and placed the new "Filters.xml" online. You can view and download them from my aforementioned Custom Filters page

If you already know where to save downloaded filters you don't need this article. Otherwise, you need this information to learn where to save updated filters. Where you save your filters file depends on both your operating system and the version of MailWasher Pro you have installed. Some, like me, use both the old and new versions simultaneously. I continue using the previous version 6.5.4, because it contains direct reporting of spam to SpamCop, for reporting members. And, the previous version has full-featured Mail Statistics and Spam Categories charts. I use the statistics and percentages reports in my weekly spam analysis articles, published on this blog, every Sunday (see my Spam and Email categories). These features are going to be added to the new version 2010 of MailWasher, at which time I and others will stop using the previous version.

If you are here out of curiosity, you can learn more about MailWasher Pro, or try it, or buy it here.

Let's move on with the locations of your spam filters, for various operating systems and versions of MailWasher Pro...

There was news today on the anti-spam front. It was just reported that the #2 spammer in the world, Leo Kuvayev, is sitting in jail, awaiting trial in Russia, on charges of molesting over 50 young girls he lured away from Russian orphanages. Kuvayev is responsible for operating bogus online pharmacies, porn sites, including child porn, pirated OEM software and related affiliate programs for these illegal activities. His organization is called BadCow and his partner in crime is running it in his absence. Many of the spam messages we receive on a daily basis are sent by Botnets under his control, or operated by his associates. The spammers themselves are affiliates of BadCow. When spam recipients are foolish enough to purchase a spamvertised item, the affiliate spammers earn a commission and Leo Kuvayev lines his pockets even more.

My incoming spam levels have decreased 4% this week, to 56% of all my incoming email. I didn't see any new types of spam this week. All the the spam that botnets are sending out this week is typical junkmail for counterfeit Chinese watches, fake Viagra, illicit prescription drugs - sans the prescription, male enhancement scams, pirated software, fake diplomas and Nigerian lottery and 419 scams. Many of the pirated software domains this week are hosted in the Ukraine. Most Russian sender spam was for counterfeit watches.

The classifications of spam in my analysis (below) can help you adjust your email filters according to what is most common, on a weekly basis. If you are using my custom MailWasher Pro filters, keep the filters for the highest percentage categories of spam near the top of the filters list, to minimize the impact on your CPU when analyzing incoming messages for spam content.

My blacklisted senders list was fairly effective this week, auto-deleting ~5.5% of all incoming spam. 57 of this week's spam messages also included my own account names in the From and Subject and most were selling fake Viagra or male enhancement junk. This illegal spam practice is known as a "Joe Job" and it is used to slip spam past our own filters. Joe Jobs depend on people white-listing their own accounts and domains. Fortunately, MailWasher custom filters allow you to override the friends list, so you can easily detect and delete Joe Job spam, if you are using MailWasher Pro as your spam filter.

Since virtually all spam is now sent from and hosted on hijacked PCs that are zombie members of various spam Botnets and all email sender addresses are forged, there is no point in complaining to the listed From or Reply To address. These accounts are inserted by the same script that composes the spam on the compromised PCs. These are innocent spam victims themselves, whose harvested names are reused in forged From addresses. This practice is known as a "Joe Job." Fortunately, MailWasher Pro has a custom filter option that overrides the "Friends" list (a Whitelist of approved senders), allowing user created spam filters to read the content and flag or auto delete spam that's using one's own accounts as the forged sender.

You can take preventative measures to secure your computers from becoming members of Botnets, by installing Trend Micro Internet Security and MalwareBytes Anti-Malware (see pages for details).

My incoming spam levels have decreased 5% this week, to 49% of all my incoming email. New this week is a run of fake, but authentic looking scams forging Amazon.com order confirmations, complete with a fake, but properly formatted purchase order code in the subject. The message bodies should be a giveaway to anybody who reads them thoroughly, because the greeting lists your email address, instead of your legal name (real Amazon orders always include your real name). Plus, the dollar amounts shown don't match or add up. Further, when you hover your pointer over the links they all go to the same destination, which is NOT on Amazon.com! These links lead to a scripted exploit attack which results in unprotected PCs becoming members of a Botnet.

As I write this I am looking at the fourth Amazon.com scam message I have received in the last 24 hours. These messages are professionally composed and very closely resemble an actual similar email that one receives after making a purchase at Amazon.com. However, there are some telltale differences, listed below, that give away the fake notices. All of the current scams have this subject:

Your Amazon.com Order (D2 numbers-7 numbers-7 numbers). This is exactly the same layout as a real confirmation for Amazon.com.

Before I tell you how to differentiate between a legitimate Amazon order confirmation and the fakes, I want to show you where you will end up if you are tricked into clicking on a link in a fake Amazon notice. In the sample of the fake notice before me, everything looks like an official order confirmation for an Amazon.com purchase, all the way down to the graphics and most, but not all of the text (see next paragraph). The main difference is that every single clickable link in the fake message leads to a domain that is not on amazon.com at all. All links lead to the same hostile location, via a 301 Apache web server redirect, created in an .htaccess file on a compromised VPS web server. The new location of this redirection is, in this instance: actcountry.ru:8080, which is hosted on a an nginx Russian web server, on an unconfigured dedicated server in France, belonging to OVH Hosting.

At this moment the payload is offline, but it could return at any time, or may appear on another server used in the domain redirection scripts. There is no doubt that the payload was not friendly to most browsers on Windows operating systems.

The rest of the details about identifying fake Amazon purchase confirmations, follow in my extended comments.

My incoming spam levels have increased 2% this week, to 54% of all my incoming email. New this week is a dangerous attachment pretending to be a scann from a Xerox WorkCenter Pro. This attack is probably targeted at businesses which may exchange Xerox documents online, or via email. In the case of this spam run, the attachments are inside a Zipfile and are actually the Trojan downloader named "Oficla," or "Meredrop." If you execute that enclosed fake document your PC will be taken over by criminal Botmasters in Eastern Europe.

Spam levels have decreased 4% this week, to 52% of all my incoming email. This decline is partly caused by my rerouting all Russian language spam to a blackhole on my server. Previously, I allowed MailWasher to classify and auto-delete all Russian sent and Russian language spam. Now, only a few Russian senders (but English language) get through, only to be automatically deleted by my MailWasher Blacklist entry: +@+.ru

The classifications of spam in my analysis can help you adjust your email filters according to what is most common, on a weekly basis. This past week again saw another typical variety of categories of spam, led by fake Viagra, illicit pharmaceuticals and male enhancement scams, followed by Russian senders, counterfeit watches, fake diplomas and pirated software.

The amount of email flagged as spam is shown on the "Summary" page of Statistics. These reports can help you adjust the order of your own spam filters.

It can be set to delete recognized spam either manually or automatically when a user-defined filter, or the built-in learning filter, or a blacklist entry, or known spam source is matched, or an attached virus is detected.

Spam levels have decreased 6% this week, to 56% of all my incoming email. This decline is partly caused by my rerouting all Russian language spam to a blackhole on my server. Previously, I allowed MailWasher to classify and auto-delete all Russian sent and Russian language spam. Fluctuations in spam levels sometimes are seasonal, or may be due to problems or successes Bot-masters have with maintaining the command and control (C&C) servers used to reactivate sleeping zombie computers in their spam Botnets. Or, these changes in spam levels may be caused when large numbers of zombie computers are disinfected, or taken offline by the ISPs who provide Internet connectivity to them. In case you didn't already know this, almost all spam is now sent from "zombie" computers in spam Botnets, unbeknownst to the owners of those infected PCs.

The classifications of spam in my analysis can help you adjust your email filters according to what is most common, on a weekly basis. This past week again saw another typical variety of categories of spam, led by fake diplomas, fake Viagra, unlicensed pharmaceuticals and male enhancement scams, Russian senders, counterfeit goods and pirated software. Keep the fake diplomas, Viagra, male enhancement, Russian sender and pirated software filters high up your list of custom filters, to minimize the impact on your CPU when analyzing incoming messages for spam content.

I have noticed that with school now out for the summer and graduation ceremonies over, fake diplomas are the number one classification of spam, for two weeks in a row. I guess that the arrogant foreign spammers behind these scams believe that our students lack the parts to earn a diploma fair and square. But, in case you are reading this and were thinking about buying a fake diploma in the hopes of getting a high paying job, you should be alerted to this cold hard fact of life. If you buy a fake diploma, when, not if, you are found out, if that diploma landed you a job you will be fired as soon as they learn the truth. Then, your former employer will notify any hiring agencies who referred you and you will be blacklisted by all US and Canadian HR companies, including Temp placement companies. They share information about people who lie on applications and use fake diplomas and credentials. If you need to get more credits to graduate, go to summer school and get it honest!

My blacklisted senders list was slightly effective this week, auto-deleting 9.39% of all incoming spam. Many (37) of this week's spam messages also included my own account names in the From and Subject and most were selling fake Viagra. This illegal spam practice is known as a "Joe Job" and it is used to slip spam past our own filters. Joe Jobs depend on people white-listing their own accounts and domains.

If you are also getting a lot of unreadable Russian spam, my custom MailWasher "Russian Sender" filter and a Blacklist addition of +@+.ru should kill all of it, if set to Automatically Delete. You can kill this Russian junk off of your domain email system, if you are hosted on a cPanel website. Go to the Email Account Level Filtering and add the following conditions and rule: If ANY HEADER contains: "koi8-r" OR if the BODY contains: "charset=koi8-r" - Discard Message.

If you are also getting a lot of unreadable Russian spam, my custom MailWasher "Russian Sender" filter and a Blacklist addition of +@+.ru should kill all of it, if set to Automatically Delete.

My blacklisted senders list was effective this week, auto-deleting ~7% of all incoming spam. Many of this week's spam messages also included my own account names in the From and Subject and most were selling fake Viagra. This illegal spam practice is known as a "Joe Job" and it is used to slip spam past our own filters. Joe Jobs depend on people white-listing their own accounts and domains. Fortunately, MailWasher custom filters allow you to override the friends list, so you can easily detect and delete Joe Job spam, if you are using MailWasher Pro as your spam filter.

Since virtually all spam is now sent from and hosted on hijacked PCs that are zombie members of various spam Botnets and all email sender addresses are forged, there is no point in complaining to the listed From or Reply To address. These accounts are inserted by the same script that composes the spam on the compromised PCs. These are innocent spam victims themselves, whose harvested names are reused in forged From addresses. This practice is known as a "Joe Job." Fortunately, MailWasher Pro has a custom filter option that overrides the "Friends" list (a Whitelist of approved senders), allowing user created spam filters to read the content and flag or auto delete spam that's using one's own accounts as the forged sender.

You can take preventative measures to secure your computers from becoming members of Botnets, by installing Trend Micro Internet Security and MalwareBytes Anti-Malware (see pages for details).

This is the latest entry in my weekly series about classifications of spam, according to my custom filter rules used by MailWasher Pro. The categories are shown on the "Statistics" page > "Junk Mail," as a pie chart, based on my custom filters and blacklist. The amount of email flagged as spam is shown on the "Summary" page of Statistics. These reports can help you adjust the order of your own spam filters.

MailWasher Pro is a POP3 and IMAP email spam screener that checks email before it is downloaded to your desktop email client. It can be set to delete recognized spam either manually or automatically when a user-defined filter, or the built-in learning filter, or a blacklist entry, or known spam source is matched, or an attached virus is detected.

Spam levels have increased 4% this week, to 66% of all my incoming email. Fluctuations in spam levels sometimes are seasonal, or may be due to problems or successes Bot-masters have with maintaining the command and control (C&C) servers used to reactivate sleeping zombie computers in their spam Botnets. Or, these changes in spam levels may be caused when large numbers of zombie computers are disinfected, or taken offline by the ISPs who provide Internet connectivity to them. In case you didn't already know this, almost all spam is now sent from "zombie" computers in spam Botnets, unbeknownst to the owners of those infected PCs.

The classifications of spam in my analysis can help you adjust your email filters according to what is most common, on a weekly basis. This past week again saw another typical variety of categories of spam, led by lots of unreadable Russian language spam, counterfeit Viagra, fake diplomas and counterfeit watches. Runners up were the bogus Canadian Pharmacy and Male Enhancement scams. Keep the Viagra, Canadian Pharmacy, Russian Sender, counterfeit Watches and Diploma filters high up your list of custom filters, to minimize the impact on your CPU when analyzing incoming messages for spam content.

I saw a slight increase in the number of emails forging my own accounts as the senders, with 50 this week, which was ~10% of my total spam. Many of these spam messages also included the same account names in the Subject and all were selling fake Viagra.

I don't know if a Botnet has been mis-programmed, or if some Russian spammers have mistaken my domain for a Russian speaking domain, but I am seeing huge amounts of unreadable Russian language spam over the past month. However, I doubt that I am the only totally English speaking person in the USA who is getting this unintelligible Cyrillic spam.

The why's are unimportant to me, or to you, if you are also getting foreign language spam. A few years ago I was getting Chinese language spam, which is totally weird to look at. Both the Russian and Chinese alphabets look like something out of Star Trek to me. Most people are annoyed when they get any spam at all. But, getting spam you can't even read is worse. Since I can't read the content I have no use in looking at this crap, so I have created spam filters to automatically delete it off my email servers, and I will share them with you.

I have certain systems in place to filter out spam before I download it, but you all might have altogether different measures in place. I will outline my countermeasures, then suggest others that you may be able to use.

My primary tool in the war to secure my inbox is an anti-spam program called MailWasher Pro (MWP). It is a desktop application that intercepts all incoming POP3 email, from all of the various email servers that I use to get and send email. In my extended comments I will reveal two powerful filters that I have created, which combined will automatically delete 100% of the Cyrillic coded spam sent to my various POP3 accounts.

My second tool is my desktop email client; Windows Live Mail (WLM). This is the most recent child of the no longer supported Outlook Express email client, from Microsoft. Outlook Express died when Windows Vista was released. At the same time, Windows Mail was included with Vista. With the advent of Windows 7, Windows Live Mail is the only email client available from Microsoft, as an optional download. Unlike Outlook Express, Windows Live Mail includes a junk filter module, which receives updates from time to time. You can also block incoming messages from your inbox by applying the new "International" filter, which reads the sender's From address or language encoding. If the domain listed in the From field, or the text coding matches one on the blocked countries list, it automatically goes to the Junk Mail folder, or is automatically deleted, according to your choices.

The previous anti spam countermeasures are for people using a POP3 or IMAP desktop email client to download, read, compose and send email. But, many people are still using browser based email systems, like Hotmail, Yahoo, AOL, Comcast, Charter, and other proprietary mail systems from free mail providers, or from their web hosting companies. You folks must search out and apply any junk mail rules available from your email service. I will show you how to apply junk filters to Yahoo and Hotmail, using your web browsers.

Most web hosting accounts now come with the option to enable Spam Assassin. You can turn on Spam Assassin and add the regular expression to block any "From" address containing the domain .ru

If you are also getting a lot of unreadable Russian spam, my custom MailWasher "Russian Sender" filter and a Blacklist addition of +@+.ru should kill all of it, if set to Automatically Delete.

My updated blacklisted senders list proved extremely effective this week, auto-deleting ~35% of all incoming spam, which included a huge amount of the aforementioned Russian language spam (see my extended content for details). I saw another decrease in the number of emails forging my own accounts as the senders, with 45 this week, which was ~9% of my total spam.

This is the latest entry in my weekly series about classifications of spam, according to my custom filter rules used by MailWasher Pro. The categories are shown on the "Statistics" page > "Junk Mail," as a pie chart, based on my custom filters and blacklist. The amount of email flagged as spam is shown on the "Summary" page of Statistics. These reports can help you adjust the order of your own spam filters.

MailWasher Pro is a POP3 and IMAP email spam screener that checks email before it is downloaded to your desktop email client. It can be set to delete recognized spam either manually or automatically when a user-defined filter, or the built-in learning filter, or a blacklist entry, or known spam source is matched, or an attached virus is detected.

Spam levels have increased slightly this week as last week, at 54% of all my incoming email. Fluctuations in spam levels sometimes are seasonal, or may be due to problems or successes Bot-masters have with maintaining the command and control (C&C) servers used to reactivate sleeping zombie computers in their spam Botnets. Or, these changes in spam levels may be caused when large numbers of zombie computers are disinfected, or taken offline by the ISPs who provide Internet connectivity to them. In case you didn't already know this, almost all spam is now sent from "zombie" computers in spam Botnets, unbeknownst to the owners of those infected PCs.

The classifications of spam in my analysis can help you adjust your email filters according to what is most common, on a weekly basis. This past week again saw a typical variety of categories of spam, led by counterfeit Viagra and other illicit and counterfeit pharmaceuticals, including spam for the totally fake Canadian Pharmacy. Other categories of spam included counterfeit watches and brand name goods and some Nigerian scams and Zbot threats in fake courier failed delivery notices. Keep the Viagra, Canadian Pharmacy, Male Enhancement and the counterfeit Watches filters high up your list of custom filters, to minimize the impact on your CPU when analyzing incoming messages for spam content.

My updated blacklisted senders list proved quite effective this week, auto-deleting 15.90% of all incoming spam (see my extended content for details). I saw a decrease in the number of emails forging my own accounts as the senders, with 69 this week, which was 18% of my total spam. Many of these spam messages also included the same account names in the Subject. This illegal practice is known as a "Joe Job" and it is used to slip spam past our filters. Joe Jobs depend on people white-listing their own accounts and domains. Fortunately, MailWasher custom filters allow you to override the friends list, so you can easily detect and delete Joe Job spam, if you are using MailWasher Pro as your spam filter.

Since virtually all spam is now sent from and hosted on hijacked PCs that are zombie members of various spam Botnets and all email sender addresses are forged, there is no point in complaining to the listed From or Reply To address. These accounts are inserted by the same script that composes the spam on the compromised PCs. These are innocent spam victims themselves, whose harvested names are reused in forged From addresses. This practice is known as a "Joe Job." Fortunately, MailWasher Pro has a custom filter option that overrides the "Friends" list (a Whitelist of approved senders), allowing user created spam filters to read the content and flag or auto delete spam that's using one's own accounts as the forged sender.

You can take preventative measures to secure your computers from becoming members of Botnets, by installing Trend Micro Internet Security and MalwareBytes Anti-Malware (see pages for details).

My updated blacklisted senders list proved slightly effective this week, auto-deleting 7.52% of all incoming spam (see my extended content for details).

The totally fake Canadian Pharmacy is back in the count, with a lot of landing pages hosted on spaces.live.com pages, as well as on Botnetted PCs. Other measurable categories of spam included counterfeit watches and other knockoffs, fake diplomas, Russian bride dating scams and UPS Phishing scams.

My updated blacklisted senders list proved very effective this week, auto-deleting almost 15% of all incoming spam (see my extended content for details).

Other measurable categories of spam included counterfeit watches, fake diplomas, pirated Adobe software, Russian bride dating scams and Phishing scams. The Phishing scams included a bunch forging the US IRS as the sender, with subjects pertaining to alleged underreported income. The links in those scams lead to the download and installation of the ZBot/Zeus Trojan keylogger and backdoor.

My updated blacklisted senders list proved very effective this week, auto-deleting over 20% of all incoming spam (see my extended content for details).

These accounts are inserted by the same script that composes the spam on the compromised PCs. These are innocent spam victims themselves, whose harvested names are reused in forged From addresses. This practice is known as a "Joe Job."

You can take preventative measures to secure your computers from becoming members of Botnets, by installing Trend Micro Internet Security and MalwareBytes Anti-Malware (see pages for details).

This is the latest entry in my weekly series about classifications of spam, according to my custom filter rules used by MailWasher Pro. The categories are shown on the "Statistics" page > "Junk Mail," as a pie chart, based on my custom filters and blacklist. The amount of email flagged as spam is shown on the "Summary" page of Statistics.

MailWasher Pro is a POP3 and IMAP email spam screener that checks email before it is downloaded to your desktop email client. It can be set to delete recognized spam either manually or automatically when a user-defined filter, or the built-in learning filter, or a blacklist entry, or known spam source is matched, or an attached virus is detected.

Spam levels have decreased 4% this week from last week's level. Fluctuations in spam levels sometimes are seasonal, or may be due to problems or successes Bot-masters have with maintaining the command and control (C&C) servers used to reactivate sleeping zombie computers in their spam Botnets. Or, these changes in spam levels may be caused when large numbers of zombie computers are disinfected, or taken offline by the ISPs who provide Internet connectivity to them. In case you didn't already know this, almost all spam is now sent from "zombie" computers in spam Botnets, unbeknown to the owners of those infected PCs.

The classifications of spam in my analysis can help you adjust your email filters according to what is most common, on a weekly basis. This past week again saw a large variety of categories of spam, including a lot of spam for counterfeit diplomas, watches and Viagra, the totally fake "Canadian Pharmacy," Russian dating scams, Nigerian 419 and lottery scams and various identity phishing scams. My updated blacklisted senders list proved extremely effective again this week, auto-deleting over 24% of all incoming spam (see my extended content for details).

Saturday, Jan 9, was the "spamiest" day this week. My blacklisted senders list proved effective again this week, catching ~13% of all incoming spam.

Not included in my statistics were several spam messages sent from hijacked PCs, faking a personal friend's account as the sender. The same message was sent to his entire group of contacts. The only body content was a link which led to an exploit web page, hosted on computers in a Botnet, all running an Nginx web server, from Russia. The exploit was based on a bogus Flash Player upgrade file, which is a Trojan Horse.

This past week saw a large variety of categories of spam, including the return of male enhancement scams, spam for the fake Canadian Pharmacy, Illicit Viagra from China, weight loss scams, counterfeit watches, loan scams and identity theft phishing scams targeting bank and UPS customers. New this week was a run of very pornographic spam promoting a dating service with a very nasty name.

The classifications of spam in my analysis can help you adjust your email filters according to what is most common, on a weekly basis. Most of the spam this week was for various unlicensed prescription drugs from China, plus weight loss, male enhancement and phishing scams. The rise in Male Enhancement scams follows a total decline that occurred a month ago, after the takedown of the Mega-D Botnet. The spammers using that Botnet have hired other Botnets to distribute their enlargement scams.

It can be set to delete recognized spam either manually or automatically when a user-defined filter, or the built-in learning filter, or a blacklist entry, or known spam source is matched, or an attached virus is detected.

Spam levels have increased 5% this week from last week's level. Furthermore, there has been a big drop in the number of male enhancement scam emails I have captured. This is almost entirely due to the hijacking and sinkholing of the Ozdok/Mega-D Botnet. That Botnet was taken down two weeks ago by the efforts of FireEye, a security firm that hijacked the Ozdok Bot command structure and redirected requests for updates from the zombies in the Botnet to a blackhole/sinkhole IP. They also notified all of the companies hosting the Command and Control servers used by the Botnet and those servers were all taken offline. This was all accomplished in a mere 24 hours, thanks to a lot of co-operation and investigative work. Unfortunately, those male enhancement spam emails are reappearing, so either Mega-D Botnet has been restored, or another Botnet is being used by the spammers promoting these fake, Chinese enhancement products.

Before the takedown, Mega-D was responsible for most of the World-wide plague of male enhancement spam messages, going back to at least 2007. Those are the messages promoting unreal enlargement results from various bogus pills and herbals.

The classifications of spam in my analysis can help you adjust your email filters according to what is most common, on a weekly basis. Most of the spam this week was for the fake Canadian Pharmacy and other unlicensed prescription drugs from China. Also, the Nigerian scammers were busy again last week, promoting their lottery scams, sent from various African countries.

Since virtually all spam is now sent from and hosted on hijacked PCs that are zombie members of various spam Botnets and all email sender addresses are forged, there is no point in complaining to the listed From or Reply To address. These accounts are inserted by the same script that composes the spam on the compromised PCs. These are innocent spam victims themselves, whose harvested names are reused in forged From addresses. This practice is known as a "Joe Job."

You can take preventative measures to secure your computers from becoming members of Botnets, by installing Trend Micro Internet Security and MalwareBytes Anti-Malware (see pages for details).

Spam levels have increased 4% this week, after two weeks in a row that spam levels had declined here. This might mean that the Bot Masters running spam Botnets may be sorting out problems maintaining their command and control (C&C) servers, used to reactivate their sleeping zombie computers (Almost all spam is now sent from "zombie" computers in spam Botnets).

The classifications of spam in my analysis can help you adjust your email filters according to what is most common, on a weekly basis. Most of the spam this week was for Nigerian 419 advance fee fraud scams, counterfeit Viagra and other brand name knock-offs. There was also a resurgence in spam using Yahoo! Groups web pages, mostly for the fake "Canadian Pharmacy," so Yahoo! needs to set up some keyword filters to detect and take down these illicit pages. Many of the "Known Spam Domain" spamvertised pharmaceutical websites were domains ending in ".cn" - which is the designation for websites hosted in China. Coincidentally, these spam messages were usually promoting the fake Canadian Pharmacy sites. Spammers try to confuse their victims with .cn domain links, because actual Canadian websites end in .ca, which many people don't realize.

Or, maybe those zombie PCs have been disinfected or taken offline. Or, maybe they are putting most of their efforts into scams on social networking sites and server exploits.

However, Bot Herders and spammers don't give up easily. If they lose one Command and Control server they will hunt for another one, often in China or Eastern Europe. Once they get those hostile servers back online, with other spam friendly hosts, the zombies are awakened and we see lots more spam.

Spam levels have decreased a bit this week, after a significant increase last week.This might mean that the Bot Masters running spam Botnets may have problems maintaining their command and control (C&C) servers, used to reactivate their sleeping zombie computers. Or, maybe those zombie PCs have been disinfected or taken offline. Whatever the explanation, spam dropped this week.

Almost all spam is now sent from zombie computers in spam Botnets, under the control of Bot Masters who rent the use of their networks to spammers. Major changes in the overall volume of spam indicate problems or successes of the Bot Masters with command and control over their robotic armies of spamming PCs. Sometimes their command and control servers are shut down by the efforts of security organizations, forcing them to look for other spam-friendly hosting companies. Other times, Microsoft's monthly Windows Updates, featuring an updated MSRT, or other security products, will clean Bot infections from millions of zombie computers. When this happens the overall volume of spam drops, as it has this week.

This is the latest entry in my weekly series about classifications of spam, according to my custom filter rules used by MailWasher Pro. The categories are shown on the "Statistics" page > "Junk Mail," as a pie chart, based on my custom filters and blacklist. The amount of email flagged as spam is shown on the "Summary" page of Statistics.

Spam levels have increased for two weeks in a row.This probably means that the Bot Masters running spam Botnets have regained access to their command and control servers, which have reactivated sleeping zombie computers. Those zombie PCs are now sending out large volumes of spam, as commanded by their Bot Masters.

Almost all spam is now sent from zombie computers in spam Botnets, under the control of Bot Masters who rent the use of their networks to spammers. Major changes in the overall volume of spam indicate problems or successes of the Bot Masters with command and control over their robotic armies of spamming PCs. Sometimes their command and control servers are shut down by the efforts of security organizations, forcing them to look for other spam-friendly hosting companies. Other times, Microsoft's monthly Windows Updates, featuring an updated MSRT, or other security products, will clean Bot infections from millions of zombie computers. When this happens the overall volume of spam drops, as it has this week.

However, Bot Herders don't give up easily. If they lose one Command and Control server they will hunt for another one, often in China or Eastern Europe. Once they get those hostile servers back online, with other spam friendly hosts, the zombies are awakened and we see lots more spam. If the Botnet loses zombies after a major cleanup, they will acquire more through compromised or hostile websites exploiting vulnerabilities in browsers and their plug-ins and add-ons.

The classifications of spam in my analysis can help you adjust your email filters according to what is most common, on a weekly basis. Most of the spam this week, especially the "Other Filters" and "Known Spam Domains" categories, was for male enhancement scams and fake Viagra. There was also a bunch of spam for illegal casinos and the fake Canadian Pharmacy.

In case anybody doesn't already know, virtually all spam is now sent from and hosted on hijacked PCs that are zombie members of various spam Botnets. All email sender addresses are forged, so there is no point in complaining to the listed From or Reply To address. These accounts are inserted by the same script that composes the spam on the compromised PCs. These are innocent spam victims themselves, whose harvested names are reused in forged From addresses. This practice is known as a "Joe Job."

See my extended comments for this week's breakdown of spam by category, for Aug 31 - Sept 6, 2009 and the latest additions to my custom MailWasher Pro filters.

On September 1, 2009, Microsoft changed the way their Hotmail email servers communicate with POP3 - SMTP desktop email clients. As of this day you cannot send or receive Hotmail through Outlook Express, period; finito, kaput! You must change to a different desktop email client, like Windows Live Mail. Microsoft Outlook users can download and install the Microsoft Outlook Connector to continue to access Hotmail. The details about these changes and what you need to do follow.

If you use Microsoft Office Outlook to send and receive through Hotmail, you can download the free Office Outlook Connector to continue accessing your Windows Live Hotmail within Outlook 2003 or 2007. If you run an older version, read this information.

If you use Outlook Express (OE) to view Hotmail, you can choose to download the free Windows Live Mail (WLM), which resembles Outlook Express, but is much more powerful, less prone to crashes and contains a junk filter. You can import all of your saved .eml messages and accounts from OE into WLM (via Export/Import, or drag and drop between email clients). You can also import your personal folders from OE. The view is a little different, but you'll get used to it. You can find help on this page with exporting messages from Outlook Express into WLM.

If you are using Entourage to send and receive Hotmail, read these instructions to continue connecting to the new servers.

New Mail Server Names:
There are also changes to the names of the Hotmail POP3 and SMTP mail servers, which now use a technology known as "Delta Sync." The new incoming POP server is: pop3.live.com and the new outgoing SMTP server is: smtp.live.com. You must also change the incoming and outgoing ports, as outlined in my extended content, under "New mail servers and ports."
