A lot of the games that are offered on the App Store might be free and then have stuff that you can buy to enhance the game through an in-app purchase. This has become very popular and even when people hack the game these in-app purchases apparently still work.
According to a UK, game development firm called Mobile Pie that in-app purchase system has now been hacked too. The game firm says that the My Star game had a 93% piracy rate in October and the app that is beating the in-app purchase system is called iAP Cracker.
The purchases on the apps were found to have been spoofed from a jailbroken phone using iAP Cracker. Apparently, the iAP Cracker was being used to spoof real purchases for credits. It’s not clear if one person wanted a bunch of credits or if something else is afoot.
