Inside Apple's iOS leak


By

Last week the iBoot source code for iOS 9 went viral after it landed on GitHub. Motherboard has an account of how the leak happened. Basically, a low-level employee removed it from Apple in 2016 and shared it with a small group of friends. Over time, the code was shared further and eventually someone posted it publically.

No one I spoke to is exactly sure who leaked it outside of the first tight-knit group of friends. And no one knew exactly what happened next. But everyone I spoke to agrees that at some point they lost control of the code and it slowly spread further and further. Motherboard confirmed that this particular source code began circulating more widely in 2017 with a fourth and fifth source who are familiar with the jailbreaking and iPhone research communities.
