http://www.itnews.com.au/newsstory.aspx?CIaNID=30724 A university systems engineer who said a Swedish hack-my-Mac contest was too easy closed down his own challenge and said that even after 4,000 log-in attempts and two denial-of-service attacks, his Mac mini remained untouched. Dave Schroeder, a senior systems engineer at the University of Wisconsin, launched his contest by setting up a fully-patched Mac mini hosting a web page, and challenging attackers to have at it. Schroeder said that the Swedish attack contest -- in which an attacker claimed he had cracked the Mac in under 30 minutes -- was deceptive. "This machine was not hacked from the outside just by being on the Internet," Schroeder wrote on his web site. "It was hacked from within, by someone who was allowed to have a local account on the box. That is a huge distinction.
