Apple's Mac App Store Hacked On First Day

Apple's launch of the new Mac App Store has already been marred with reports of hackers coming up with ways to pirate paid apps on the platform.

Hackers have discovered a simple copy-paste method to illegally crack some of the paid apps on the Mac App Store.

The method involves replacing the receipt and signature files on a paid app package with ones taken from a free app. Angry Birds is just one of the apps which can be hacked in this manner.

According to Apple Insider, Apple did provide support for App Store receipts on Mac OS X 10.6.6 but it is clear that Apple failed to check the Mac App Store for vulnerabilities like this before launching it yesterday.

A report on technology blog Daring Fireball informs that the vulnerability only affects those apps which don't follow Apple's app validation advice, in which the application is required to check for a valid receipt along with making sure that the receipt matches the app's bundle ID. monitors all leading technology stories and rounds them up to help you save time hunting them down.
