NSS Labs - Bounties for exploits
ExploitHub, which operates a penetration-testing site and is run by NSS Labs, announced a bug-bounty program for researchers to develop exploits for 12 high-value vulnerabilities in Microsoft and Adobe products. The company, which has set aside $4,400 in reward money, plans to give $100 to $500 to the first people to submit a working exploit for the vulnerabilities. Ten of the vulnerabilities concern Microsoft's Internet Explorer browser and two were found in Adobe's Flash multimedia program.
