The 7th volume of the Microsoft Security Intelligence Report (SIR) was released today. The top finding is that worms infections in the enterprise rose by nearly 100 percent during the first half of 2009.
According to the report, rogue security software remained the single largest threat category for the first half of 2009. Microsoft products and services removed such malware from more than 13 million computers worldwide, down from 16.8 million in the second half of 2008.
The SIR provides a deep, accurate view of the threat landscape country-by-country and, for the first time, the SIR includes security best practices from countries that have consistently exhibited low malware infection, such as Japan, German and Austria.
Data for the SIR is collected through a wide variety of means, including but not limited to: Microsoft’s Malicious Software Removal Tool, Bing, Windows Live OneCare, Windows Defender and, of course, Forefront solutions.
The full SIR, guidance and other resources are available here.
