14 DAY TRIAL // Google has revealed that no one managed to break Chrome OS' protection in the Pwnium 3 competition, which focused on Google's laptop operating system.
However, there were some exploits that worked to a degree and Google is currently investigating the entries to determine the rewards.
Alongside Pwn2Own, which it partially sponsored, Google also ran the Pwnium 3 security competition. Pwnium came about last year when Google decided to part ways with Pwn2Own over a dispute on exploit disclosure.
But the rules of Pwn2Own changed this year, contestants had to describe the bugs they used and how they exploited them, and Google came back as a sponsor.
It didn't shelf Pwnium though, rather it made it all about Chrome OS. Would-be hackers had to successfully take control of a Samsung Series 5 500 Chromebook and would get rewarded based on how far along they got.
"Pwnium 3 has completed and we did not receive any winning entries. We are evaluating some work that may qualify as partial credit," Google said in a statement.
"Working with the security community is one of the best ways we know to keep our users safe, so we’re grateful to the researchers who take the time to help us in these efforts," it added.
Google offered a $3.14159 million (€2.3361 million) in total for any exploit that would break out of the Chrome sandbox, with bonus points, and money, if the attack resulted in complete control of the device.
The top prize was $150,000 (€110,000) for an attack that would take over the device and be persistent between reboots and users. $110,000 (€82,000) was offered for a successful but non persistent attack.
It doesn't seem like any of those targets were made. There were several security researchers that tried their luck though and Google may reward them for the bugs they found, even if they're not as dangerous or if they can't be easily exploited.
