Google's Chrome Security team has taking the wraps of its its latest Pwnium competition. This time out, the target is Chrome OS on a Samsung Series 5 550, and as ever, the company's putting its money (and nerd cred) where its mouth is, offering up a $Pi million in rewards (that's a lofty $3.14159 million) for the third round of the competition. Amongst the payouts are $110,000 for a "browser or system level compromise in guest mode or as a logged-in user, delivered via a web page" and $150,000 for a "compromise with device persistence -- guest to guest with interim reboot, delivered via a web page." The company is also putting some weight behind the upcoming Pwn2Own competition, which goes down at CanSecWest in Vancouver in March. More info on both can be found at the source link below.
