The fifth edition of the Pwn2Own contest gets underway at the CanSecWest conference here this week. The contest began as a timed competition to see who could find and exploit a vulnerability in a fully patched MacBook Pro running the most current version of OS X. Researchers went at the machines for hours, trying to find a new bug and develop a reliable exploit for it. Win, and you got not only the computer that you d exploited but a nice $10,000 cash prize.
