F-Secure: Adobe Reader Most Exploited Software

Computerworld reports that F-Secure says 61 precent of the nearly 900 targeted attacks it's tracked in the first two months of 2010 took advantage of a vulnerability in Reader. Meanwhile, Microsoft's portion of targeted attack exploits has been steadily declining. Last year, Word, Excel and PowerPoint exploits made up approximately 51 percent of attacks, a drop from the 71 percent of all targeted attacks those applications made up in 2008.

It seems Adobe is constantly scurrying to protect its products. Just last month, it released two out-of-band patches for a pair of "critical" vulnerabilities in Reader and Acrobat, which hackers are already taking advantage of.

Unfortunately for Adobe, this isn't the first time that a security company has awarded Adobe dubious honors. Last month, ScanSafe said rogue Reader documents made up 80 percent of all exploits at the end of 2009.
