Sloppy coding in some popular iOS games allows hackers to give themselves and others thousands of dollars’ worth of in-app purchases for free.

The hole was discovered by developers at DigiDNA, creator of a backup tool called iMazing that allows iPhone and iPad users to access their devices’ hidden file systems. The developers found that the app backup/restore feature in iMazing 1.3 exposes weaknesses in the way games like Angry Birds 2 and Tetris Free handle in-app purchases.

To demonstrate how easy it is to hack in-app purchases using this method, the DigiDNA team tweaked Angry Birds 2 to start the game with 999,999,999 gems — the equivalent of $10,000 of in-game credits.

Hit TV show Family Guy followed a trajectory that’s very similar to Apple’s. The show appeared as a breath of fresh air early on, underwent a decline during which it almost vanished, then made a triumphant return.

In that way, Family Guy always seemed a perfect fit for iOS. Earlier this year, that pairing finally happened when developer TinyCo debuted Family Guy: The Quest for Stuff, a mobile game that follows Peter Griffin and the rest of the Fox TV show’s colorful supporting cast as they rebuild the town of Quahog after it’s been destroyed.

Six months down the line — and with the game currently in the middle of a haunting, courtesy of its Halloween update — Cult of Mac spoke with the developers about Seth McFarlane, making games funny, and the perils of in-app purchases.
