The iBoot code was initially shared online several months back on Reddit, but it just resurfaced today on GitHub (repository now unavailable due to DMCA takedown). Motherboard consulted some security experts who have confirmed the legitimacy of the code.
The leaked iBoot code appears to be from a version of iOS 9, which signifies that the code is not entirely relevant to the latest iOS 11.2.5 operating system, but some parts of the code from iOS 9 are likely still used by Apple in iOS 11.
It is worth noting that newer iPhones and other iOS devices ship with Secure Enclave, which protects against some of the potential issues that come with the leaked iBoot source code. So, I really doubt that the leaked code will be of much help.
Apple has yet to comment on the recent leak, though Github has already disabled the repository that was hosting the iBoot code after the company issued a DMCA takedown notice. However, the code is already out there.
