 One year after launching a controversial Macintosh hacking contest, the promoters of the CanSecWest security research conference are thinking about giving hackers another shot at cracking the Mac. Only this time, they're looking to broaden the field. 
Last year, show organizers invited attendees to hack into a Macintosh laptop with the successful hacker winning the computer
                     and a cash prize. But this year, they're talking about giving attendees three targets to choose from. "We're thinking of having
                     a contest where we have Vista and OS X and Linux ... and see which one goes first," said Dragos Ruiu, the principal organizer
                     of CanSecWest.
                   
                  Last year, security researcher Dino Dai Zovi spent a sleepless night hacking his Mac in order to take the prize at the show's
                     first PWN to OWN contest. Dai Zovi found a QuickTime bug that allowed him to run unauthorized software on the Mac once the computer's browser was directed to a specially crafted
                     Web page.
