As part of Google's bug bounty program, researchers have been granted financial rewards based on the severity of the issue. A number of rewards are yet to be decided upon, but at the time of writing the most critical flaws earned researchers cash rewards ranging from $500 to $7500. In total, roughly $40,000 has been awarded to security researchers.

Besides the table above, Google said there are also over 100 smartphone models that run an Android version with a security patch from the last 90 days (three months). Despite this, the vast majority of today's smartphones run outdated versions of the Android OS.

Furthermore, Google announced it would be paying an insane amount of money to researchers who deliver two types of bug reports.

  • $200,000 to any security researcher who files a bug report for a remote exploit chain or exploit leading to TrustZone or Verified Boot compromise. Google was previously paying $50,000 for this type of bug report.
  • $150,000 to any security researcher who files a bug report for a remote kernel exploit. Google was previously paying $30,000 for this type of bug report.

The increase of this reward comes after a failed contest organized last year. In September 2016, Project Zero, a division of the Google security team specialized in finding zero-days, announced a contest that would have paid $200,000 (first place), $100,000 (second place), and $50,000 (third place) for a full exploit chain that would compromise Android devices.

The contest was so hard that no researcher submitted any bug reports, albeit some told Google they were working on it.

Google paid $1.5M+ for Android bug reports in the last 2 years

In addition to the increase of bug report payouts for the above two vulnerability types, Google also released details about its Android bug bounty program, known as the Android Security Rewards program.

According to the company, after two years, they've paid out over $1.5 million in rewards to 115 individuals (or security teams) for 450 valid vulnerability reports.
