Google has never been stingy when it comes to paying for information about security vulnerabilities in products. Now it’s offering an especially large–and especially nerdy–sum of money.At its third Pwnium hacking competition in Vancouver in March, the company is ponying up a total of $3.14159 million in prizes for hackers who can demonstrate critical security vulnerabilities in its Chrome OS operating system running on a Samsung Series 5 550 Chromebook, according to a notice posted Monday on its Chromium blog. Any participant who can take over a Chromebook user’s browser or entire computer via a malicious Web page can earn a $110,000 payout.
