More from M86Security's report:

Exploits in the second half of 2011 targeted a variety of products, including Microsoft Internet Explorer, Oracle Java, Microsoft Office productsand quite commonly, Adobe Reader and Adobe Flash. Security fixes for some of these vulnerabilities have been available for years, whichpoints out a continuous problem: Many users and organizations do not patch all their installed software in a timely manner, and attackersleverage this weakness to their advantage.As the table shows, more than half of the most exploited vulnerabilities are used by the prevalent Blackhole exploit kit.

Based on the report, the BlackHole web malware exploitation kit remains the most popular client-side exploits serving kit, representing 95.1% of observed malicious URLs. M86Security contributes the growth of the BlackHole web malware exploitation kit due to the frequent updated issues by the  coders of the kit, including the very latest remotely exploitable vulnerabilities.

The report's findings confirm the findings from previously released reports indicating that outdated and already patched vulnerabilities remain among the key driving forces for the success of cybercrime.

End users are advised to ensure that they're running the latest versions of popular software, as well as browser plugins, to avoid exploitation through client-side exploits.
