500 USD Reward for Security Hackers

The Mozilla Foundation today announced the Mozilla Security Bug Bounty Program, an initiative that rewards users who identify and report security vulnerabilities in the open source project's software. Under the new program, users reporting critical security bugs - as judged by the Mozilla Foundation staff - will collect a $500 cash prize. The new initiative was launched with funding from leading Linux software developer Linspire, Inc., and renowned Internet entrepreneur Mark Shuttleworth. (Emphasis by me)

Pretty cool, isn't it? ;-)
