[iPhone] Apple’s AppStore DRM broken

You don’t trust DRM protections? You read that Microsoft and Yahoo switched off their DRM servers thus disallowing the continuous use of legally bought Music?

Then this might be the news for you. Sources that wish to stay anonymous confirmed and explained that removing of AppStore’s DRM of your legally bought applications is fairly simple for people who know what a command line is.

The technique only requires a jailbroken iPhone that got SSH installed. Once you legally bought the application you can run it on your iPhone / iPod Touch. Then you log in via SSH, determine the process ID and dump a part of the memory. Since the application needs to be decrypted in order to run on your iPhone it will be decrypted before it’s going to be executed. So in memory you have the decoded binary and you only need to dump in to a file. Using the GNU debugger here makes your life easy. After that you only need to replace the part of the encrypted binary with the memory dump and set a flag to not encrypted. People who know what ProcDump in the early Windows days did: this is exactly the same technique without the automatization.

Anyway we’re not sure if more concrete information may violate Germany’s weird intellectual property rights, we can’t go into further details here. We recommend to do a Google search. You will most likely find one or two tutorials that go in to detail step by step. Applying that technique will allow you to save your very bought apps. We don’t condone misuse or piracy.

    There is no DRM that can’t be cracked. Very simple.

    DRM only annoyes legit customers for getting limited in fair use. When will the companies begin to comprehend this?

    DRM is the only way to stop piracy. Yes there were probs with the Microsoft and Yahoo servers. But seriously: do you really like to hear music, you listened to years ago. Same applies to software. Who wanna use all the old AppStore apps in say two or three years?

    Man are you reflecting yourself sometimes? Music can’t get old.

    Anyway: it is my decision what I’d like to do with Apps and Music. I have simply paid for it. The last weapon we consumers have is our money. And I will definitly not pay for things that are DRM protected.

    What if Steve suddenly dies of cancer. Apple will be a f*cked company. Apple stocks go down, because there is nobody else to manage that company in the Steve way. Apple will go down and I? I have paid lots of money for DRM protected legal music that I cannot use anymore and that I cannot transfer to other devices. If I had downloaded all that stuff from torrent trackers in the first place there would not be any of these limitations.

    Means: the industry shows us going legit is the stupid way. Going the illegal way is lasting.

    What you’re saying is really bullsh*t, sorry dude.
