Recently there was a MAJOR leak of much of the source code from iOS's BootRom and iBoot software.
Previously this information was secured in Apple's Secure Enclave Processor, which meant it was very difficult to find exploits and vulnerabilities. But now, that could all change.
iPhone source code leak Apple cracks down on 'iOS bootloader' posted on GitHub. The leaked code could provide clues to vulnerabilities that could be used to compromise, jailbreak, and decrypt iOS devices.

The code is actually from iOS 9, but most of that code is probably still in use today.

Someone has published the purported source code for the iOS bootloader, iBoot, potentially opening the door for **hackers and jailbreakers **to find **vulnerabilities in Apple's **mobile OS.
Motherboard reports that the iBoot source code for iOS 9 was leaked on GitHub and, although
it is an older version of iOS, parts of it probably remain in the current iOS 11.
Another thing is the Bootrom can only be updated via a hardware update, so Apple could be in trouble if a major exploit was found there. This could also mean that jailbreaking will be much easier soon since there will be many more opportunities to find jailbreak vulnerabilities in
iPhones and other iOS devices.
