Microsoft Security Intelligence Report 2H09 released

Microsoft has  released it Security Intelligence Report with a focus on the second half of 2009.

Microsoft Security Intelligence Report provides in-depth perspectives on malicious and potentially unwanted software, software exploits, security breaches, and software vulnerabilities in both Microsoft and third party software.

Here are some of the highlights:

  • The top 5 locations with the most computers cleaned by Microsoft desktop anti-malware products in 2H09 were USA, China, Brazil, UK & Spain.
  • Two of the largest increases in the number of computers cleaned were experienced by China and Brazil, which increased 19.1 percent and 15.8 percent from 1H09, respectively.
  • Windows 7, which was released in 2H09, and Windows Vista with Service Pack 2 have the lowest infection rates of any platform on the chart. The 64-bit versions of Windows 7 and Windows Vista SP2 had lower infection rates (1.4 for both) than any other operating system configuration in 2H09, although the 32-bit versions both had infection rates that were less than half of Windows XP with its most up-to-date service pack, SP3.
  • Microsoft security products cleaned rogue security software–related malware on 7.8 million computers in 2H09, up from 5.3 million computers in 1H09—an increase of 46.5 percent, which suggests that rogue security software provides its distributors with large payoffs relative to some other, less prevalent kinds of threats.
  • Comparing exploits that target Microsoft software to third-party exploits suggests that the vulnerability landscape of Windows Vista and Windows 7 is very different from that of Windows XP. In Windows XP, Microsoft vulnerabilities account for 55.3 percent of all attacks in the studied sample. In Windows Vista and Windows 7, the proportion of Microsoft vulnerabilities is significantly smaller, accounting for just 24.6 percent of attacks in the studied sample.
