I went through Apple's DMCA requests sent to Github and the only one that is remotely similar is this: https://github.com/github/dmca/blob/master/2014-11-04-Apple.... But even then they weren't claiming it was reverse engineered material, but instead material ripped directly from Apple's copyrighted and confidential docs. I think both Apple and Github understand the boundaries of the DMCA pretty well. According to Github they haven't attempted to take down any of the following: https://github.com/nygard/class-dump https://github.com/nst/iOS-Runtime-Headers https://github.com/brutella/hc https://github.com/KhaosT/HAP-NodeJS https://github.com/nfarina/homebridge https://github.com/lisimia/piMessage https://github.com/stefanesser/dumpdecrypted https://github.com/comex/imaon2 … etc

Sure! It's a combination of static and dynamic analysis. I have a jailbroken phone, which allows me to access any file on the filesystem and decrypt any App Store binaries[1]. The first step is to find in which binaries the functionality lives. I know from searching that AirDrop lives in Sharing.framework[2], which has a supporting daemon, sharingd. Then, I open the binaries in a disassembler like IDA Pro[3] or Hopper[4] to determine how they work. Running class-dump is also helpful[5]. If I need to inspect a process like sharingd at runtime, I use Cycript[6], which gives me an Objective-C REPL into the process, or LLDB[7].

> Sounds like they haven't really broken apple's DRM Yes and no. No, in the sense that they are abusing the pay-for Apple developer services in order to get the software pushed to non-jailbroken devices. As such, they are still playing within the DRM system. But in the case of Zeusmos, yes, Apple's DRM (FairPlay) is broken in that "re-signing" involves signing a copy of the (App Store published) commercial app that had its original DRM removed. See here: https://github.com/stefanesser/dumpdecrypted These techniques were how tools like Crackulous worked, which allowed for the stealing of iOS App Store apps in the first place.
