According to these sources, the person who stole the code didn’t have an axe to grind with Apple. Instead, while working at Apple, friends of the employee encouraged the worker to leak internal Apple code. Those friends were in the jailbreaking community and wanted the source code for their security research.
The person took the iBoot source code—and additional code that has yet to be widely leaked—and shared it with a small group of five people.
“He pulled everything, all sorts of Apple internal tools and whatnot,” a friend of the intern told me. Motherboard saw screenshots of additional source code and file names that were not included in the GitHub leak and were dated from around the time of this first leak.
Baseband code from the same time period has also been leaked publicly.
