Isn’t it fun when a new version of Mac OS X comes out and you get to learn about all these security companies that you never heard of before? Not really, but Mike Lennon reports on a possible vulnerability in 10.6 and 10.7:

The Mac OS vulnerability relates to user login passwords that are stored in the system memory even if the computer is locked or put into a sleep mode. Passware’s software captures live Mac computer memory over FireWire and analyzes it, extracting these passwords, a process that the company says takes just a few minutes–regardless of password strength and use of a FileVault encryption.

So I guess a good defense would be to use a MacBook Air because it doesn’t have FireWire?
