Hackers have discovered a way to exploit the Real World Auction House in Diablo 3. Blizzard has shut down the post on their forums, but the information is spreading.
Supposedly, it involves editing code inside the game. Lagspike.tv will not post or publish the hack, but knowledge such a thing even exists is another black mark against Blizzard's popular game. With some people attempting to make a living through the auction house, any exploit against real money is a real problem. PCI compliance means such transactions must be made securely, or credit card companies will refuse to honor transactions. Blizzard had best find a way to fix this problem before it runs into credit troubles.
