Vista, Leopard, Linux to compete in hack contest
Run by the organizers of the CanSecWest Vancouver 2008 security conference, the competition is a repeat of the "PWN to Own" contest at CanSecWest in 2007, when security researchers competed to win a MacBook Pro and US$10,000. The prize was shared between security researchers Dino Dai Zovi and Shane Macauley for their successful use of a zero-day QuickTime vulnerability, which they used to compromise the MacBook. The vulnerability was subsequently found to also affect Windows platforms.
