Google promoted Chrome 51 to the stable channel last week after squashing multiple bugs and security vulnerabilities. Along with the release, the company also revealed the amount paid out to external researchers for reporting some of these issues.
As you may remember, Google has an active Rewards program for reporting bugs and vulnerabilities in its Chrome browser and across its online properties. The company has now revealed the list of researchers who reported 23 vulnerabilities in Chrome 51.

The total amount paid out to these external researchers is $65,000 which is still less than what a single person can get for hacking a Chromebook remotely. Nonetheless, researcher Mariusz Mlynski snagged $30,000 for reporting four cross-origin bypass vulnerabilities in Chrome.
Google is said to have restricted the access to the bug details until significant number of users have a version of Chrome that isn"t affected by the vulnerabilities.
