Since 2010, Google has been paying money to hackers who have found problems with its hardware or software. And after the challenge last year to crack its Chromebook’s security system went unanswered, Google is now doubling its reward to $100,000.

The $100,000 payout applies to anyone who can crack the so-far-undefeated Chromebook, but Google also has a bunch of other prizes for smaller bugs.

These payouts start at $500 – and if you provide a fix with your bug submission, you get $1,337.

Google also says that any problems uncovered – regardless of whether there’s an official bounty – could be eligible for a reward, but the company admits that the rules for submissions that deserve cash payouts are relatively strict.

It’s weird that a tech company would encourage people to bust down the walls, but that’s exactly what’s happening here. Google even ended its bounty announcement with an encouraging note: “Happy hacking!”
