An avid bug hunter has discovered a vulnerability in Valves Steam developer portal which, exploited properly, reveals every license key for every game available on the platform. Artem Moskowsky reportedly stumbled across the bug by mistake, while taking an innocent stroll down the site. Instead of selling the keys for illicit profit, he reported the flaw to Valve, who patched the flaw and gave him a $15,000 bounty. The company also gave him an additional $5,000 bonus for finding a bug in the same platform.”]
