Google's Pwnium ends with no winners

According to a Google+ posting from Google, there were no winners in Google's own Pwnium competition, which followed Pwn2Own at the CanSecWest conference in Canada. Google had offered a prize fund, inspired by the constant pi, of $3.14159 million with $110,000 prizes if the browser or system could be compromised and $150,000 prizes if the compromise could be persisted over a reboot. The target for the attacks was a Series 5 550 Chromebook running the latest stable ChromeOS.

Google's fast patching of an exploit that was used by MWR Labs to win $100,000 at Pwn2Own in the preceding two days was fortuitous for Google as it allowed them to eliminate that vulnerability in ChromeOS before the competition began. Despite extending the competition on the day, Google says it did not get any winning entries. There were, the company said, some entries which "may qualify as partial exploits".
