Here's the article. This was a fully patched Macbook running current software and new security patches. A follow-up article also showed that one security expert managed to hack IE8 and Firefox (using a zero day exploit) on Windows, however it happened later in the day. Here are the results from the event. Note that the Safari export works by a person clicking a link, per the rules of the contest no application was downloaded or ran on OS X, just the simple act of clicking a link allows remote control of OS X. This is the 3rd year in a row that OS X was the first to fail in security because of Safari exploits. Windows Vista running IE8 and Firefox was only hacked because of an Adobe Flash exploit. Ubuntu remained unscathed... Safest route would be to run Firefox on OS X and to NOT run in an Admin account. Interesting isn't it?
