We have noticed an uptick of inquires on our site about the Trojan Horse Zues Win32/Zbot. This bot was originally discovered in January 2010 but appears to be rearing its ugly head again with a vengeance. Zeus is a banking malware trojan, and specializes in stealing personal information (passwords, account information, etc) from interactions with banking sites through the use of “formgrabs”. This generally means that this trojan is distributed through spam campaigns and drive-by downloads form the web.
Now that a computer(s) has been infected on your network the trojan really gets to work. The bot will then attempt to send out infected emails without being detected. This will more than likely cause your mail server IP to become listed on the CBL Blacklist.
Now you may be asking yourself: How did I get infected when I have Anti-Virus on all machines and am blocking Port 25 traffic on my email server? You have done the majority of the work to protect yourself by locking the front door (Anti-Virus) and the back door (block Port 25), but you may have unknowingly left the window open (Web Filtering). With up to 85% of malware now distributed via the Web, proactive Web security is a necessity.
