Valve plugs an API bug found in its Steam platform that that abused the Smart2Pay system to add unlimited funds to gamer digital wallets.
A security researcher helped Valve, the makers of the gaming platform Steam, plug an easy-to-exploit hole that allowed users to add unlimited funds to their digital wallet. Simply by changing the account’s email address, the exploit allowed anyone to artificially boost their digital billfold to anything they wanted.
Steam Wallet funds are exclusive to the Steam platform and are used to purchase in-game merchandise, subscriptions and Steam-related content. Valve restricts Steam credits (or money) from being transferred outside its network for purchase or trading. However, there are several unsanctioned ways to convert wallet funds into actual dollars.
Working for the HackerOne bug-bounty program, security researcher DrBrix, reported the bug last Monday. By Wednesday, Valve plugged the hole and paid DrBrix $7,500 for identifying the bug.
