IPhone hacker Charlie Miller compromised a MacBook Air in a mere two minutes at CanSecWest security conference. He won $10,000 in prizes by hacking the Air after the judges visited a web site Miller created for the contest. None of the contestants were able to hack into the MacBook, a Sony VAIO running Linux, or a Fujitsu U810 on the first day because the rules state they could not induce the judges to visit websites or run executables. Once they relaxed the rules, Miller won handily. They were required to hack into at least one of the boxes using a yet-unreleased hack. Miller apparently used a Safari exploit to compromise the MacBook, giving him full access to the machine over the network.
