Our Microsoft Malware Protection Center (MMPC) has just released the latest Security Intelligence Report for July through December. The report has a number of interesting findings, but the most eye-popping is a 300 percent increase in Trojans, using our enormous sample size of 450 million computers:
During the second half of 2007 there was a 300% increase in the number of Trojan downloaders and droppers detected and removed. The increase observed in 2H07 is vastly larger than the already large increase observed between 2H06 and 1H07. Clearly this category of malware has become a tool of choice for some attackers. IT Professionals and Security Professionals alike should become familiar with this type of malware so that they can better protect their networks from attacks that leverage it.
We're sure glad we have some of the best anti-malware researchers in the world building our anti-malware engine for Forefront Client Security.
