Apple ordered GitHub to remove iOS source code leak A portion of iOS’s source code was leaked online yesterday and quickly removed after Apple filed a takedown notice with GitHub, where the code was posted. The leak, which was first reported by Motherboard, was for an iOS process named “iBoot” that starts up the system when you first turn on your iPhone and ensures the code being run is valid and originates from Apple. It was posted to GitHub at this link, which is now down. The leak could allow hackers to discover iOS vulnerabilities more easily and make creating iPhone jailbreaks simpler, even in the face of Apple’s tightened security measures. Although the code has now been taken down, there are still backups of it circulating on the web, as mentioned by a post on r/jailbreak.
