As reported earlier CanSecWest conference was designed to test zero day vulnerability against three leading desktop operating systems. The result is out:
 The MacBook Air went first
 Windows Vista was cracked (hacked) on the last day of the contest
 Linux remained undefeated
Although several attendees tried to crack the Linux laptop, nobody could pull it off, said Terri Forslof, a manager of security response with TippingPoint. "I was surprised that it didn't go," she said.
