Pwn2Own browser exploit challenge is set to run from March 9 to March 11 at the CanSecWest security conference. The contest pits researchers against each other in an attempt to hack through the browser or mobile operating systems of eight different targets. The first group to successfully hack a device or browser wins a cash prize of $15,000 for each, with a special reward of $20,000 going to a group that successfully manages to crack Google’s Chrome browser. Microsoft has not released any patches to its Internet Explorer 8 browser prior to the contest.
