Google (GOOG) offered hackers a chance at a big pay day if they could crack its Chrome OS platform. The company held its annual Pwnium competition at the ConSecWest security conference in Vancouver this week where it put $3.14159 million up for grabs. While a number of hackers attempted to get a piece of the Pi, a Google spokesperson confirmed in a statement to TechCrunch that none of them succeeded in fully cracking the operating system. The company did reveal, however, that it is “evaluating some work that may qualify as partial credit.” Google is making a big push to boost consumer interest in Chrome OS. The company recently released the high-end Chromebook Pixel to compete directly with the Retina display Macbook Pro.
