Google has extended its proactive Patch Reward Program to include even more open-source software. Among them is the Android Open Source Project, which the company previously did not reveal was going to be added. Last month, Google started providing financial incentives (between $500 and $3,133.70) for proactive improvements to OSS that go beyond merely fixing a known security bug. Google said at the time it would be rolling out the program gradually, and hinted that more project types would be on the way.
