2009 Year in Mac Security Report Released

"Mac OS X and iPhones that haven't been jailbroken fare pretty well (although vulnerabilities exist, there's not been a lot of exploitation). Apple does come in for criticism for 'time to fix' known vulnerabilities. Jailbroken iPhones are a mess. The biggest risk to Macs are Trojan horses, often from pirated software."

 Interesting that one of the biggest complaints in the report is how Apple handles reports of problems with the security of OS X, which unfortunately is very slowly. Even after acknowledging that OS X could be vulnerable, and placing an anti-malware feature in Snow Leopard, the report states that  "as of January 2010, this anti-malware feature has not been updated, and still scans for the same two Trojan horses and nothing else."
