A year ago, we added Android Security Rewards to the long standing Google Vulnerability Rewards Program. We offered up to $38,000 per report that we used to fix vulnerabilities and protect Android users. Since then, we have received over 250 qualifying vulnerability reports from researchers that have helped make Android and mobile security stronger. The program is focused on Nexus devices and has a primary goal of improving Android security. Fixing bugs helps improve security of the broader mobile industry (and even some non-mobile platforms)”]
