On the final day of the PWN 2 OWN contest, only the Linux box was left standing.
Vista fell after 2 days of intensive effort, the winner used a flaw in the Java runtime to gain control of the Windows box. It wasn't all plain sailing though, Shane McCauley needed help from VMWare's Alexander Sotirov to get his code working. Apparently, Vista SP1 comes with additional security measures that he wasn't expecting. He also got a little help from co-worker Derek Callaway (does this mean they share the computer they won?)
