After Mac was hacked in 2 minutes at the CanSecWest Conference, it was now the time for Vista to get hacked on the 3rd day.
Vista's security was compromised through the popular 3rd party software, Adobe Flash.
"The contest, which saw a MacBook Air get hacked on Thursday, relaxed the rules even further. On the first day of the contest, only the operating system could be targeted, but on the second day that was expanded to include standard applications. An undisclosed Safari flaw led to the MacBook Air's downfall through the OS X operating system."
The MacBook Air went first; a Fujitsu laptop running Vista was hacked on the last day of the contest; but it was Linux, running on a Sony Vaio, that remained undefeated as conference organizers ended a three-way computer hacking challenge Friday at the CanSecWest conference.
