Fake FedEx email with message in image and malware attachments

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.

My Spam analysis & filter updates for the week of Aug 23 - 29, 2010

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 increased 6% this week, to 54% of all my incoming email. I saw a few new courier infected attachment exploits this week. All the the rest of the spam was typical junkmail for counterfeit Chinese watches, fake Cialis and Viagra, illicit prescription drugs, male enhancement scams, pirated software, and fake diploma scams.

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).

See my extended comments for this week's breakdown of spam by category, for August 23 - 29, 2010, and the latest additions to my custom MailWasher Pro filters and Blacklist.

MailWasher Pro spam category breakdown for August 23 - 29, 2010. Spam amounted to 54% of my incoming email this week. This represents +6% change from last week.

Effective August 22, 2010, the custom filters are written for all versions of MailWasher versions. There is a brand new version 2010 that was just released in July, 2010, which uses a totally different xml filter format. After many hours of hand editing, I have converted the old filters into the new xml format. You can download my spam filters from my MailWasher Pro spam filters page

Here are some facts from my MailWasher Statistics for the past week. Of the 464 incoming email messages that were classified as spam, 414 were classified by my custom filters, 19 were from my custom Blacklist, and 5 from the DNS Servers Blacklist (mostly the SpamCop Blocklist (SBL)). I actually saw 50 spam messages (but classified by filters set to manual deletion, for safety), all of which I reported through my SpamCop reporting account. The rest were automatically deleted by my custom filters and Blacklist. See the updates to my filters below the spam categories list.

finger pointing right MailWasher Pro by Firetrust
Fake Cialis & Viagra (dangerous): 21.23%
Watches (ripoffs): 14.16%
Pharmaceutical Spam (dangerous & illegal): 13.47%
Counterfeit goods (cufflinks, etc): 11.19%
Other Filters (misc filters with small percentages): 8.68%
Known Spam Domain Links (mostly .RU - Russian): 8.45%
Male Enhancement Scams (fake & dangerous): 8.45%
Blacklisted Senders (dating scams & Viagra, etc): 4.34%
Pills (and herbal junk): 4.11%
Diploma scams (don't fall for these!): 2.28%
Infected ZIP file attachments: 1.37%
Pirated Software (often containing Trojans): 1.14%
DNS Blacklists (SpamCop, Spamhaus,etc.): 1.14%

There were 3 updates to my custom spam filters this week, and no updates to the blacklist. The latest updates to my custom MailWasher Pro filters were to these filters:

Misspelled Viagra
Unlicensed Prescription Drugs
New filter: Eastern European Sender

The following recent MailWasher Pro Email Blacklist entries were able to block ~4.3% of this week's spam. Some weeks will have higher percentages of blacklisted senders, depending on which Botnets are used to send those messages, with forged sender names and email addresses. Since the Blacklist is processed before the custom filters, the processing time and cpu load is greatly reduced.

Note: The blacklist expressions in large type are usually extremely effective! Note, that is you set a custom filter to Take Precedence over the Friends list, it also overrides the Blacklist, which is in the same file.

Note, that the Blacklist works in both the old and new versions of MailWasher Pro. You can import the Blacklist from version 6.x when you move up to MailWasher Pro 2010 and newer.

About MailWasher Pro

MailWasher Pro intercepts POP3 and IMAP email before you download it to your desktop email client (e.g: Microsoft Outlook, Outlook Express, Windows Live Mail) and scans it for threats or spam content, then either manually or automatically deletes any messages matching your pre-determined criteria and custom filters. It is my primary line of defense against incoming spam, scams, phishing and exploit attacks. If you are not already using this fine anti-spam tool I invite to to read about it on my MailWasher Pro web page. You can download the latest version and try it for free for a month. Registration costs just $29.95, with an annual renewal fee of only $9.95, to cover the costs of development and the FirstAlert community spam database.

All of the spam and scams targeting my numerous accounts were either automatically deleted by my custom MailWasher Pro spam filters, or if they made it through, was reported to SpamCop, of which I am a reporting member, and manually deleted.

If you use a POP email client on your desktop to send and receive your email, rather than your browser, you too will benefit from the added protection that MailWasher Pro provides. I can't even begin to tell you how many dangerous attachments, exploit encoded messages, 419 fraud, as well as courier, bank, eBay and PayPal phishing scams, plus hundreds of hostile link emails it has deleted, after identifying them with my rules and its own heuristic and known spam detections.

I am available for hire to write custom MailWasher Pro filters for you or your company. They require that you have a copy of MailWasher on each computer to be customized.

Finally, many security threats will come to you via spam email; some in hostile attachments, some as "phishing" scams, some as financial fraud or money laundering scams, and many more in links to web pages rigged to serve up exploit codes or Trojan downloads.You need really good up-to-date protection to fight off the multitude of attack codes flying like machine gun bullets these days. To protect your computer from web pages rigged with exploit codes, malware in email attachments, dangerous links to hostile web pages, JavaScript redirects, Phishing scams, or router DNS attack codes, I recommend Trend Micro Internet Security (or Internet Security Pro for travelers). It has strong realtime monitoring modules that stop rootkits and spam Trojans from installing themselves into your operating system. Also known as PC-cillin, it is very frequently updated as new and altered malware definitions become available and it checks for web based threats and new malware definitions by searching secure online servers owned by Trend Micro. This is referred to as "in-the-cloud" security. Best of all, you can try it fully functional for a month, then decide to pay to keep it or uninstall it.

See you all next week, same time, same station! Keep the sunny side up and don't take no wooden nickles!

Where to save my updated MailWasher Pro spam filters

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...

Location of MailWasher Pro user files and filters

MailWasher Pro is currently a Windows only application. People are currently working on porting it to Mac and Linux distributions (under WINE). This information only pertains to Windows users.

If you are using Windows 2000 or XP, all of your user files, filters, lists and preferences are saved under your logged in identity's Application Data directory (a.k.a: "folder"). MailWasher Pro version 6x and older will find their user files in their "C:\Documents and Settings\username\Application Data" directory, inside a sub-folder named "MailWasherPro." Windows XP users who install the new MailWasher Pro 2010 will find their user files inside an Application Data sub-folder named "Firetrust" > "MailWasher." (Sorry Windows 2000 users. No new version for you!)

If you have Windows Vista or Windows 7, your user files are found under the C:Users\username\AppData\Roaming directory. Your MailWasher files will be under a sub-folder named Firetrust\MailWasher, for the new 2010 version, or MailWasherPro for the old version (up to 6.x).

One well established way of getting to your Application Data folder, for your logged in identity, is to open the Run box (Windows key + R) and type in this command, then press Enter: %AppData% . Your Application Data directory will open as a window with folders. Find the appropriate folder for your version of MailWasher Pro and double click to open it.

An even simpler way of opening your actual MailWasher Application Data folder is available to version 2010 users. Go to the Help menu and click on it, then go down to the link labeled: "User Files" and click on it. Your personal user data files for MailWasher 2010 will open in a window. The one you are looking for for version 2010 is named: "Filters.xml"

The filters file name for the previous series 5 and 6 is "filters.txt"

How to replace your MailWasher Pro (MWP) filters.

Once you have open your MailWasher Pro application data folder, close the MailWasher program, if it was open. We do this because any changes you make to the filters, while the program is actively running, will be overwritten by the existing or default set, as soon as you close the program.

With MWP closed, right-click on your filters file and rename it to something like: filters-sav.(txt or xml). Then, download your desired updated version of my custom filters and save it to the appropriate MailWasher Pro AppData folder. If you don't rename the existing filters first, Windows will pop-up a challenge box asking if you wish to replace the existing file with the new one. I would save the previous working version beforehand.

You can also download my custom filters to your desktop, or a download folder of your choice. Once the file is downloaded, open it in your preferred text editor (Notepad, NoteTab Pro, Wordpad, Notepad Plus, etc). Then find your existing filters file and open it in another instance or tab of your text editor. Then, drag and drop the updated filter sections into your existing file and save the changes (make a backup first!). This way, you can keep your own personalized custom filter rules intact, while just updating the changes to the general spam rules I publish.

Save all changes, leave the text editor open with the changes visible, then open MailWasher. If it fails to show some or all of the updated rules, something was copied wrong. In the new version, a bad rule may cause all of the custom filters to disappear and be replaced with the default set. Maybe there was one bad character in an update for the new version (it is touchy that way). That's why I said to always save a backup before you edit your filters file.

Close MailWasher, but leave the filter file open in the text editor. As long as you don't close that file, even the bad rules will be visible and editable.

With the saved rules open you can select all and copy to a new text file. Then delete all but your personalized rules you know were working. Begin pasting in the new rules, one at a time, saving as you go, then opening MailWasher, until you find the bad one. Edit it until it is working, or remove it and contact me, or the Firetrust MailWasher Pro forum for help.

You can also hire me to convert your own personalized MailWasher spam filters from version 6x to the new xml format. I can also create a custom filter set to meet your personal requirements. Contact me here and request technical assistance. My hourly rate is reasonable.

Security updates released for Adobe Acrobat & Reader

On Thursday, August 19, 2010, Adobe released critical "out of cycle" security updates, 9.3.4 and 8.2.4, for its commercial Acrobat PDF encoder and free Adobe PDF Reader programs. Today's updates fix at least two critical vulnerabilities that are being exploited in the wild. Exploitation of these vulnerabilities could cause the application to crash and could potentially allow an attacker to take control of the affected system.

Updates are available for Windows, Mac and UNIX versions of these Adobe programs. Windows users may receive automatic updates notices, or may be auto-updated, depending on how you have set your updater preferences (Edit > Preferences > Updater). You can also check manually, buy going to the Help menu item, then down to "Check for updates." An updater window will open separately, download the new version upon receiving your permission. It will close Reader or Acrobat, then install then new version. If you were working on any PDF documents, save them and exit the application during the update phase. It may take some time to complete (I don't know why, it just does!).

The official Common Vulnerabilities and Exposures code for today's update is: CVE-2010-2862, which was discussed and demonstrated at the Black Hat USA 2010 security conference on Wednesday, July 28, 2010. The actual vulnerability is described as: "Integer overflow in CoolType.dll in Adobe Reader 8.2.3 and 9.3.3, and Acrobat 9.3.3, allows remote attackers to execute arbitrary code via a TrueType font with a large maxCompositePoints value in a Maximum Profile (maxp) table."

Further details are: "Network exploitable; Victim must voluntarily interact with attack mechanism" - which they are tricked into doing.

Vulnerability details were provided and/or discovered by: Charlie Miller, Independent Security Evaluators, and Tavis Ormandy, Google Security Team.

All of this follows on the heels of another out-of-cycle critical update in Adobe's Flash Player, on August 11. It appears that Adobe Acrobat and Reader bundle a version of Flash inside the program, and that version was exploitable, via authplay.dll. The new updates to Reader and Acrobat supply the latest, patched version of Flash, bundled inside those programs.

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.

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).

See my extended comments for this week's breakdown of spam by category, for August 9 - 15, 2010, and the latest additions to my custom MailWasher Pro filters and Blacklist.

MailWasher Pro spam category breakdown for August 9 - 15, 2010. Spam amounted to 56% of my incoming email this week. This represents -4% change from last week.

Please note that these filters are written for MailWasher versions up to 6.5.4. There is a brand new version that was just released this month, which uses a totally different filter format. I am going to be rewriting my filters to work in the new 2010 version, but they are not yet available for public use.

Here are some facts from my MailWasher Statistics for the past week. Of the 364 incoming email messages that were classified as spam, 322 were classified by my custom filters, 19 were from my custom Blacklist, and 4from the DNS Servers Blacklist (mostly the SpamCop Blocklist (SBL)). I actually saw 30 spam messages (but classified by filters set to manual deletion, for safety), all of which I reported through my SpamCop reporting account. The rest were automatically deleted by my custom filters and Blacklist. See the updates to my filters below the spam categories list.

finger pointing right MailWasher Pro by Firetrust
Viagra (dangerous): 20.29%
Known Spam Domain Links (mostly .RU): 17.39%
Watches: 13.91%
Pharmaceutical Spam (dangerous): 10.43%
Male Enhancement Scams (dangerous): 9.86%
Diploma scams: 5.80%
Blacklisted Senders (dating scams & Viagra, etc): 5.51%
Other Filters (misc filters with small percentages): 5.22%
Pills: 4.64%
Pirated Software (on Russia websites): 3.77%
Counterfeit Goods: 1.16%
DNS Blacklisted Servers: 1.16%
Lottery Scams: 0.87%

There were 7 updates to my custom spam filters this week, and 1 update to the blacklist. The latest updates to my custom MailWasher Pro filters were to these filters:

Software Spam
Unlicensed Prescription Drugs
Updated "Viagra.com Spam" and renamed it to "Viagra Spam [From]"
Viagra Spam [From]
Viagra Spam [S]
Viagra Spam [S] #2"
New filter: Pics Spam

The following recent MailWasher Pro Email Blacklist entries were able to block ~5.5% of this week's spam, especially from senders in Russia. Some weeks will have higher percentages of blacklisted senders, depending on which Botnets are used to send those messages, with forged sender names and email addresses. Since the Blacklist is processed before the custom filters, the processing time and cpu load is greatly reduced.

Note: The blacklist expressions in large type are extremely effective! Note, that is you set a custom filter to Take Precedence over the Friends list, it also overrides the Blacklist, which is in the same file.

Note, that the Blacklist works in both the old and new versions of MailWasher Pro. You can import the Blacklist from version 6.x when you move up to MailWasher Pro 2010 and newer.

About MailWasher Pro

MailWasher Pro intercepts POP3 and IMAP email before you download it to your desktop email client (e.g: Microsoft Outlook, Outlook Express, Windows Live Mail) and scans it for threats or spam content, then either manually or automatically deletes any messages matching your pre-determined criteria and custom filters. It is my primary line of defense against incoming spam, scams, phishing and exploit attacks. If you are not already using this fine anti-spam tool I invite to to read about it on my MailWasher Pro web page. You can download the latest version and try it for free for a month. Registration costs just $29.95, with an annual renewal fee of only $9.95, to cover the costs of development and the FirstAlert community spam database.

All of the spam and scams targeting my numerous accounts were either automatically deleted by my custom MailWasher Pro spam filters, or if they made it through, was reported to SpamCop, of which I am a reporting member, and manually deleted.

If you use a POP email client on your desktop to send and receive your email, rather than your browser, you too will benefit from the added protection that MailWasher Pro provides. I can't even begin to tell you how many dangerous attachments, exploit encoded messages, 419 fraud, as well as courier, bank, eBay and PayPal phishing scams, plus hundreds of hostile link emails it has deleted, after identifying them with my rules and its own heuristic and known spam detections.

I am available for hire to write custom MailWasher Pro filters for you or your company. They require that you have a copy of MailWasher on each computer to be customized.

Finally, many security threats will come to you via spam email; some in hostile attachments, some as "phishing" scams, some as financial fraud or money laundering scams, and many more in links to web pages rigged to serve up exploit codes or Trojan downloads.You need really good up-to-date protection to fight off the multitude of attack codes flying like machine gun bullets these days. To protect your computer from web pages rigged with exploit codes, malware in email attachments, dangerous links to hostile web pages, JavaScript redirects, Phishing scams, or router DNS attack codes, I recommend Trend Micro Internet Security (or Internet Security Pro for travelers). It has strong realtime monitoring modules that stop rootkits and spam Trojans from installing themselves into your operating system. Also known as PC-cillin, it is very frequently updated as new and altered malware definitions become available and it checks for web based threats and new malware definitions by searching secure online servers owned by Trend Micro. This is referred to as "in-the-cloud" security. Best of all, you can try it fully functional for a month, then decide to pay to keep it or uninstall it.

See you all next week, same time, same station! Keep the sunny side up and don't take no wooden nickles!

Spybot Search & Destroy updates for August 11, 2010

Spybot Search & Destroy is a free (for personal non-business use) anti-spyware/spyware removal program used by millions of people around the World, to protect their computers from spyware, adware, Trojans and other types of malware. Spybot updates for malware detections are released every Wednesday and this week's updates were released on schedule. If you are using Spybot S&D to protect your computer you should check for updates every Wednesday afternoon and apply all that are available.

Malware writers are constantly modifying their programs to evade detection, so anti-malware vendors have to issue regular updates to keep up with the bad guys. New definitions and false positive fixes for Spybot Search and Destroy are usually released every Wednesday. This week's updates were released on schedule, as listed below. These detections include new or modified fake (rogue) security programs (fraudulent anti virus/spyware; scareware) (Malware), Trojan downloaders, password stealers, rootkits, DDoS attack bots and spam bots. It is imperative to keep your security tools updated and scan frequently for malware threats.

Note: one + sign before a detection indicates an update to an existing malware family for which previous definitions have been released. Two ++ signs indicate a completely new detection of a new or rewritten malware type.

An anti-spyware program that is updated once a week cannot protect you from malware threats created or modified and released in the last 24 - 48 hours. If you want realtime protection against the most current spyware, keyloggers, rootkits, rogue anti-virus and security programs, Trojans and other forms of malware, with very frequent automatic updates, scheduled malware scans and the blocking of known-hostile IP addresses, you should try Malwarebytes Anti-Malware. Malwarebytes Anti-Malware

Total: 3090503 fingerprints in 1057887 rules for 5711 products.

False Positives Reported This Past Week

There were 2 false positives reported this week.

1: A file named ww1138.exe - an update for win3.1x calculator, was detected as Win32.Monderb.aqpu. This has been fixed with the current updates.

2: A confirmed false positive was fixed today for "Win32.Wemon.sh" - [SBI $1ACF3A39] Settings (Registry change, fixed) - HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List\

Aways make sure you are using the current version of Spybot S&D, before updating definitions or scanning. Older versions tend to give false positives, or fail to adequately remove detected malware.

Notes about the detection categories

If you see updates in the "PUPS" category, this means Possibly Unwanted/Unpopular Programs. They appeal to many social networkers but may track your surfing habits and report on your computer configuration, without your explicit knowledge. These often include some smiley programs, screensavers and browser toolbars.

"Spyware" includes applications that track your surfing and report to a third party without your permission.

"Keyloggers" record your keystrokes and steal logon credentials to your bank, trading company, website and server control panels, PayPal, eBay, etc.

"Malware" means Malicious Software and includes among other things - fake/rogue anti virus, anti spyware, system security and registry scanners and infection alerts. These often appear on hostile websites, or websites that have been hacked to redirect you to places where false alerts and scans are launched. The goal is to panic you into purchasing the program to remove the (fake) infections. This is really a soft form of extortion and is generally referred to as scareware and rogue security alerts.

Note, that people who pay for scareware to remove the fake alerts are giving their credit or debit card numbers and security codes to criminals. Most live in the former Soviet Union and are associated with the RBN.

"Trojans" pretend to be a required missing Codec, Flash update, plug-in, or news report, or porn player, whereas they are really the worst malware that installs remote control (Bot) software and rootkits into your PC. Like the Trojan Horse of ancient Troy, once installed, Trojan Horse programs hand the keys to your PC castle to cybercriminals!

Installing or uninstalling and Immunizing Spybot S&D

Installing, upgrading to a new version, or uninstalling Spybot requires Administrator level privileges. Updating definitions does not require these permissions most of the time. But, to immunize against all threats does require Admin privileges. If you. like me, operate as a Power/Standard User, you can right-click on the icon to launch Spybot S&D and Run As (an) Administrator. From there you can download the latest definitions, immunize completely and scan/disinfect with full administrator authority.

Updating Spybot Search and Destroy

Before you update Spybot Search and Destroy make sure you have the latest official version. Older versions are no longer supported and will cause you a lot of grief when you immunize and scan for problems. Only download Spybot S&D from the official website, at: spybot.info, or from its alternate domain: Safer-Networking.org. Fake versions with similar names will rip you off for payment to remove threats, whereas the real Spybot Search & Destroy is free for personal use. No subscriptions, no download fees, but, donations are gladly accepted.

In case you are new to Spybot S&D, there are two ways to update the program and malware definitions. The preferred method (For Windows PCs) is to go to Start > (All) Programs > Spybot - Search & Destroy > Update Spybot - S&D. The independent update box will open. Leave the default options as is, unless you need all languages or want beta definitions, and click on "Search." Another box will open with "mirror" locations around the world where you can download updates. Select a location nearest to you from the list and click on "Continue." Make sure all updates are checked, then click on "Download." If all definitions are verified as being correct the check marks will disappear from the check boxes and be replaced with green arrow graphics. However, sometimes one or more mirror locations have not updated all of the definitions and you will get a red X for those definitions. Click on Go Back, select a different mirror, and try again. I have consistent success using Giganet or the Safer-Networking servers. When all updates have succeeded, click on "Exit."

You can also download the latest definition includes file from a clean PC and save them to a removable disk or drive, then install them into the Spybot S&D program while the infected PC is offline. This helps you disinfect a PC that cannot presently get online, or cannot access security websites for updates (because of the Conficker or similar malware), or due to other networking problems. The downloaded definition includes will look for a typical Spybot installation location and will update it instantly, as long as the program is closed during the updating process.

Download links and more instructions about using Spybot Search and Destroy are in my article titled "How to use Spybot Search & Destroy to fight malware".

TeaTimer false positives

In the case of Teatimer false positives that are fixed by updates, TeaTimer will have to be restarted after the update is applied. TeaTimer cannot be updated with new definitions if it is still running! After you update definitions to fix false positives, a restart of either TeaTimer or the Computer is required. If this doesn't fix the false positives, you may need to reset the TeaTimer detection list, as follows:

Right click the (TeaTimer) Resident tray icon
Select "Reset lists"

Alternately, close and restart TeaTimer using this method:

* start Spybot S&D
* switch to advanced mode
* navigate to "Tools" , then "Resident"
* uncheck the check box for Resident TeaTimer to close TeaTimer
* wait a bit so TeaTimer can unload completely, for instance wait 1min
* check the check box for Resident TeaTimer again to restart the TeaTimer

If that fails also, please read the rest of the things to try on this forum page, in replies #2 and #4.

When TeaTimer blocks the file you can also allow the file to be executed (also remove the check mark for deletion). You can exclude any file from further detections during a scan by right clicking the items in the Spybot S&D scan result and select "exclude this detection from further searches"

Malware fingerprints are frequently changed by their purveyors, to slip past definition based anti-malware tools. As malware detections and behavioral analysis modules increase in complexity, so does the possibility of false positives. For this reason it is often a good idea to quarantine suspected malware rather than deleting it, until the next weekly Spybot definitions have been released. Scan the quarantined items again and if they are still detected as malware, delete them after a week or two. You can also open a new thread on the Spybot False Positives Forum to see if your detection is real, or a false positive.

If you are running several brands of security software, make sure that only one active protection (realtime monitoring) feature runs at a time. In case you want to deactivate the TeaTimer, to avoid conflicts, you can do this in Spybot S&D advanced mode in Tools - Resident, as described above.

Adobe Releases Security Update for Flash Player

August 11, 2010

Adobe Releases Security Update for Flash Player: Adobe has released Flash Player 10.1.82.76 to address multiple vulnerabilities. See Go here for the details.

See what version of Flash you have installed for each browser brand, here. If you use the current version of Firefox it will tell you to update Flash, when a new version has been released. Internet Explorer users still need to go to Adobe and update the ActiveX version manually.

Due to exploits in the wild, you are strongly advised to update your Flash players now! Adobe recommends users of Adobe AIR 2.0.2.12610 and earlier versions update to Adobe AIR 2.0.3, by downloading it from the Adobe AIR Download Center.

Note, that previously, one could navigate to C:\Windows\System32\Macromed\Flash and use the FlashUtil(version#).exe application to run a manual update. Those files no longer work that way. Now, the FlashUtil apps uninstall Flash, rather than update it. You can download the new Flash installers, named: install_flash_player_ax.exe, for Internet Explorer based browsers, and install_flash_player.exe, for Mozilla based browsers (non-ActiveX), from the Adobe Flash Download Center. Administrator privileges are required to install or update Flash via these installer files. Use "Run As" (Administrator & password) if necessary.

A word of warning!
As you browse the Internet, or read emails about watching movies online, always beware of any links that take you to a page that tells you to update your Flash Player, but the link does not go to www.adobe.com, or http://www.adobe.com/go/getflash/ . Cyber criminals are famous for creating fake Flash and YouTube players, with a spinning circle in a black player screen, telling you that your Flash Player needs updating and click there. If you hover your mouse over those links you may or may not see that they never leave that website. The files you are about to downland and run from these fake web pages are Trojan Horse programs designed to make your PC a member of a Botnet, or install rogue security scanners, or a login stealing Trojan, like the Zeus/Zbot Trojan.

If you are tricked into clicking on a fake media player and a download dialog appears, dismiss it immediately, then close your browser. Use your anti-virus scanner to see if malware was downloaded into the browser's cache and remove it, or clear the cache. Always update your anti-malware definitions before scanning for new threats.

My Spam analysis for the week of August 2 - 8, 2010

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 increased 9% this week, to 60% 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 Vietnam and China. 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 quite effective this week, auto-deleting ~7% of all incoming spam. 66 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.

See my extended comments for this week's breakdown of spam by category, for August 2 - 8, 2010, and the latest additions to my custom MailWasher Pro filters and Blacklist.

MailWasher Pro spam category breakdown for August 2 - 8, 2010. Spam amounted to 60% of my incoming email this week. This represents +9% change from last week.

Please note that these filters are written for MailWasher versions up to 6.5.4. There is a brand new version that was just released this month, which uses a totally different filter format. I am going to be rewriting my filters to work in the new 2010 version, but they are not yet available for public use.

Here are some facts from my MailWasher Statistics for the past week. Of the 407 incoming email messages that were classified as spam, 352 were classified by my custom filters, 28 were from my custom Blacklist, and 7 from the DNS Servers Blacklist (mostly the SpamCop Blocklist (SBL)). I actually saw 54 spam messages (but classified by filters set to manual deletion, for safety), all of which I reported through my SpamCop reporting account. The rest were automatically deleted by my custom filters and Blacklist. See the updates to my filters below the spam categories list.

finger pointing right MailWasher Pro by Firetrust
Watches: 21.71%
Viagra (dangerous): 15.76%
Known Spam Domain Links (mostly .RU): 15.50%
Other Filters (misc filters with small percentages): 9.30%
Blacklisted Senders (dating scams & Viagra, etc): 7.24%
Male Enhancement Scams (dangerous): 6.46%
Pharmaceutical Spam (dangerous): 5.94%
Diploma scams: 5.17%
Pills: 4.65%
Pirated Software (on Russia websites): 2.58%
Known Spam [From]: 2.07%
Counterfeit Goods: 1.81%
DNS Blacklisted Servers: 1.81%

There were 8 updates to my custom spam filters this week, and 4 updates to the blacklist. The latest updates to my custom MailWasher Pro filters were to these filters:

Image Spam #11,
Known Spam [From],
Lottery Scam,
Male Enhancement [B] (2x),
Nigerian 419 Scam #6,
Pills,
Viagra [B]

The following recent MailWasher Pro Email Blacklist entries were able to block ~7% of this week's spam, especially from senders in Russia. Some weeks will have higher percentages of blacklisted senders, depending on which Botnets are used to send those messages, with forged sender names and email addresses. Since the Blacklist is processed before the custom filters, the processing time and cpu load is greatly reduced.

This is referred to as "in-the-cloud" security. Best of all, you can try it fully functional for a month, then decide to pay to keep it or uninstall it.

See you all next week, same time, same station! Keep the sunny side up and don't take no wooden nickles!

My Spam analysis for the week of July 26 - Aug 1, 2010

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 increased 2% this week, to 51% 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 fake Viagra, illicit prescription drugs - sans the prescription, male enhancement scams, Nigerian lottery and 419 scams, Fake diplomas, counterfeit watches and pirated software. All of the pirated software is hosted on websites ending with .RU, which are Russian domains. The servers allowing this crap to go on are located in China.

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 quite effective this week, auto-deleting ~10% of all incoming spam. 41 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).

See my extended comments for this week's breakdown of spam by category, for July 26 - Aug 1, 2010, and the latest additions to my custom MailWasher Pro filters and Blacklist.

MailWasher Pro spam category breakdown for July 26 - Aug 1, 2010. Spam amounted to 51% of my incoming email this week. This represents +2% change from last week.

Please note that these filters are written for MailWasher versions up to 6.5.4. There is a brand new version that was just released this month, which uses a totally different filter format. I am going to be rewriting my filters to work in the new 2010 version, but they are not yet available for public use.

Here are some facts from my MailWasher Statistics for the past week. Of the 315 incoming email messages that were classified as spam, 268 were classified by my custom filters, 30 were from my custom Blacklist, and 3 from the DNS Servers Blacklist (mostly the SpamCop Blocklist (SBL)). I only saw 22 spam messages (but classified by filters set to manual deletion, for safety), all of which I reported through my SpamCop reporting account. The rest were automatically deleted by my custom filters and Blacklist. See the updates to my filters below the spam categories list.

finger pointing right MailWasher Pro by Firetrust
Viagra: 23.59%
Watches: 17.61%
Blacklisted Senders (dating scams & Viagra, etc): 9.97%
Other Filters (misc filters with small percentages): 9.63%
Pharmaceutical Spam: 7.97%
Diploma scams: 7.31%
Male Enhancement Scams: 6.98%
Known Spam Domain Links (mostly .RU): 4.98%
Counterfeit Goods: 4.65%
Known Spam [From]: 2.99%
Lottery Scams: 1.66%
Pirated Software (on Russia websites): 1.66%
DNS Blacklisted Servers: 1.00%

There were 0 updates to my custom spam filters this week, and 0 updates to the blacklist. The latest updates to my custom MailWasher Pro filters were to these filters:

The following recent MailWasher Pro Email Blacklist entries were able to block ~10% of this week's spam, especially from senders in Russia. Some weeks will have higher percentages of blacklisted senders, depending on which Botnets are used to send those messages, with forged sender names and email addresses. Since the Blacklist is processed before the custom filters, the processing time and cpu load is greatly reduced.

Note: The blacklist expressions in large type are extremely effective! Note, that is you set a custom filter to Take Precedence over the Friends list, it also overrides the Blacklist, which is in the same file.

Note, that the Blacklist works in both the old and new versions of MailWasher Pro. You can import the Blacklist from version 6.x when you move up to MailWasher Pro 2010 and newer.

About MailWasher Pro

MailWasher Pro intercepts POP3 and IMAP email before you download it to your desktop email client (e.g: Microsoft Outlook, Outlook Express, Windows Live Mail) and scans it for threats or spam content, then either manually or automatically deletes any messages matching your pre-determined criteria and custom filters. It is my primary line of defense against incoming spam, scams, phishing and exploit attacks. If you are not already using this fine anti-spam tool I invite to to read about it on my MailWasher Pro web page. You can download the latest version and try it for free for a month. Registration costs just $29.95, with an annual renewal fee of only $9.95, to cover the costs of development and the FirstAlert community spam database.

All of the spam and scams targeting my numerous accounts were either automatically deleted by my custom MailWasher Pro spam filters, or if they made it through, was reported to SpamCop, of which I am a reporting member, and manually deleted.

If you use a POP email client on your desktop to send and receive your email, rather than your browser, you too will benefit from the added protection that MailWasher Pro provides. I can't even begin to tell you how many dangerous attachments, exploit encoded messages, 419 fraud, as well as courier, bank, eBay and PayPal phishing scams, plus hundreds of hostile link emails it has deleted, after identifying them with my rules and its own heuristic and known spam detections.

I am available for hire to write custom MailWasher Pro filters for you or your company. They require that you have a copy of MailWasher on each computer to be customized.

Finally, many security threats will come to you via spam email; some in hostile attachments, some as "phishing" scams, some as financial fraud or money laundering scams, and many more in links to web pages rigged to serve up exploit codes or Trojan downloads.You need really good up-to-date protection to fight off the multitude of attack codes flying like machine gun bullets these days. To protect your computer from web pages rigged with exploit codes, malware in email attachments, dangerous links to hostile web pages, JavaScript redirects, Phishing scams, or router DNS attack codes, I recommend Trend Micro Internet Security (or Internet Security Pro for travelers). It has strong realtime monitoring modules that stop rootkits and spam Trojans from installing themselves into your operating system. Also known as PC-cillin, it is very frequently updated as new and altered malware definitions become available and it checks for web based threats and new malware definitions by searching secure online servers owned by Trend Micro. This is referred to as "in-the-cloud" security. Best of all, you can try it fully functional for a month, then decide to pay to keep it or uninstall it.

See you all next week, same time, same station! Keep the sunny side up and don't take no wooden nickles!
