My Spam analysis for May 25 - 31, 2009
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.
The volume of spam coming to my various honeypots and user accounts has been steadily increasing over the past month. This is due to the activity of various wounded spam Botnets coming back to life (after the takedown of McColo), or new ones like the Russian Cutwail Botnet, being pressed into service. The classifications of spam in my analysis can help you adjust your email filters according to what is most common, on a weekly basis. Much of the spam this week was for the fake Canadian Pharmacy, which sells illicit and counterfeit pharmaceuticals, Nigerian 419 scams, fake watches and Viagra, "stud" tips and male enhancement scams (same websites). I also saw an increase in Australian banking phishing scams this week.

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 is only required once, for the life of the program.
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. 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.
All of the spam and scams targeting my 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. MailWasher Pro is able to forward messages marked as spam to SpamCop, which then sends a confirmation email to you, containing a link. You must click on the enclosed reporting link and open it in your browser, then manually submit your report. This is how SpamCop wants it done.
