It seems that the Mac App Store, which was launched on January 6, has been cracked already. The crack will not be available until February 2011 though, according to Dissident, the hacker who created the hack – Kickback.
We don’t want to release Kickback as soon as the [Mac App] Store gets released. I have a few reasons for that.
Most of the applications that go on the Mac App Store [in the first instance] will be decent, they’ll be pretty good. Apple isn’t going to put crap on the App Store as soon as it gets released. It’ll probably take months for the App Store to actually have a bunch of crappy applications and when we feel that it has a lot of crap in it, we’ll probably release Kickback.
So we’re not going to release Kickback until well after the store’s been established, well after developers have gotten their applications up. We don’t want to devalue applications and frustrate developers.
It has already been widely reported that the security of the Mac App Store is very easy to circumvent. The team that developed Kickback is a part of the Hackulous community that cracked Apple’s DRM system for iOS.
