Google has increased the maximum payment of its Chrome bug bounty programme, claiming that hunters have already helped it to fix over 700 security flaws.
Chrome Security Team hacker philanthropist Tim Willis announced in a blog post that Google will increase the payments from $500-to-$5,000 per bug to $500-to-$15,000 per bug.
Willis said that Google chose to increase the maximum payment as the success of the programme means there are no longer any "easy bugs" for researchers to find.
"Due in part to our collaboration with the research community, we've squashed more than 700 Chrome security bugs and have rewarded more than $1.25m through our bug reward programme," read the post.
"But as Chrome has become more secure, it's gotten even harder to find and exploit security bugs. This is a good problem to have! In recognition of the extra effort it takes to uncover vulnerabilities in Chrome, we're increasing our reward levels."
He added that the firm will continue to make special allowances and pay more for bugs it deems worth more than the standard fee.
"As always, we reserve the right to reward above these levels for particularly great reports. For example, last month we awarded $30,000 for a very impressive report," said Willis.
As well as the increased payment Google will also celebrate "all star" bug hunters' achievements using a new Google Hall of Fame programme that will list the best discoveries.
Google also announced a wave of reforms to its submission policy designed to make it easier for hunters. The change means that hunters will now have the option to submit the vulnerability first and follow up with an exploit later.
Willis said the changes will make it quicker and easier for Google to spot bugs and for hunters to receive payment.
"We believe that this a win-win situation for security and researchers: we get to patch bugs earlier and our contributors get to lay claim to the bugs sooner, lowering the chances of submitting a duplicate report," read the post.
In a final bid to keep bug hunters happy, Google has confirmed it will back-pay valid submissions from 1 July under the new payment model.
Google is one of many firms to extend the remit of its bug bounty programme in recent weeks. Microsoft expanded its programme to include Outlook, Office365, Sharepoint, Lync, Windows.net, Microsoftonline.com and Yammer flaws on 24 September.
