So far, Chrome is the only browser of the big four -- Safari, Firefox, and Internet Explorer being the other three -- to escape the Pwn2Own hacking competition unscathed the past two years. (Sorry Opera aficionados, looks like there's not enough of you to merit a place in the contest... yet.) Evidently, its past success has Google confident enough to pony up a cool $20,000 and a CR-48 laptop to anyone able to find a bug in its code and execute a clean sandbox escape on day one of Pwn2Own 2011. Should that prove too daunting a task, contest organizer TippingPoint will match El Goog's $10,000 prize (still $20,000 total) for anyone who can exploit Chrome and exit the sandbox through non-Google code on days two and three of the event. For those interested in competing, Pwn2Own takes place March 9th through 11th in Vancouver at the CanSecWest conference. The gauntlet has been thrown -- your move, hackers.
