Microsoft Security Intelligence Report - Volume 6

The Microsoft Security Intelligence Report (SIR) provides an in-depth perspective on the changing threat landscape including software vulnerability disclosures and exploits, malicious software (malware), and potentially unwanted software. Using data derived from hundreds of millions of Windows users, and some of the busiest online services on the Internet, this report also provides a detailed analysis of the threat landscape and the changing face of threats and countermeasures and includes updated data on privacy and breach notifications. The sixth volume of the report is now available

SIR Volume 6 (July through December 2008) and Key Findings Summary (available in 10 languages)

Infections by rogue security software (sometimes called "scareware") spiked dramatically worldwide in the second half of 2008.

Watch as Vinny Gullotto (General Manager, Microsoft Malware Protection Center) and Tim Rains (Group Product Manager, Trustworthy Computing) discuss this threat and analyze the key trends from volume 6 of the Security Intelligence Report.

Security Intelligence Report Volume 6 - Selected Key Findings

Malicious software infection rates differ significantly for different versions of the Microsoft Windows operating system.
Windows Vista was less infected at any service pack level than Windows XP.
Comparing the latest service packs for each version, the infection rate of Windows Vista SP1 is 60.6 percent less than that of Windows XP SP3.

The total number of unique vulnerability disclosures across the industry again decreased during the second half of 2008, down 3% from the first half of 2008 and down 5% from the second half of 2007.

In contrast to the decrease in total disclosures, vulnerabilities rated as High severity increased 13% with respect to the second half of 2007, with roughly 48% of all vulnerabilities receiving a rating of High severity. This is still a 28% decline from the first half of 2007.

The following heat map illustrates the infection rates of locations around the world, expressed in a metric called CCM that represents the number of computers cleaned per thousand executions of the Malicious Software Removal Tool.
