Mac App Store into this world by reportedly discovering loopholes which allow them to plunder its wares for free. According to BBC News, one such loophole -- which only works on certain Apps and includes mobile darling Angry Birds -- simply requires the user to copy and paste the application's in-store purchase code. Why, that doesn't sound very difficult at all.
A group of hackers by the collective name of Hackulous also reported to BBC News that its developed a piece of software titled Kickback which can break the copy protection on any App on the store. A representative from the group told BBC, "We're not going to release Kickback until well after the store's been established," as they "don't want to devalue applications and frustrate developers."
