Hackproof Linux
Earlier this week, contest sponsors put three laptops up for anyone who could hack into one of the systems and run their own software.
A $20,000 cash prize was offered but the prize was halved each day, as contest rules were relaxed and it became easier to penetrate the computers.
A Fujitsu laptop running Vista was hacked on the last day of the contest. But what about the third computer running Linux?
A Sony Vaio with Ubuntu running on it remained undefeated as conference organisers ended their hacking challenge.
