In early February, iBoot, which is code from the secure boot-up part of Apple’s iOS mobile operating system, was leaked online and posted to GitHub. Apple sent GitHub a Digital Millennium Act takedown request, thus confirming it was indeed genuine code, and while GitHub did remove the code, it was online for a few hours. This may have lasting and damaging effects for the security of Apple devices, as the code could be used by people creating software to jailbreak or bypass Apple’s protection of iPhones and iPads. According to comments in the leak, the leaked code is from iOS 9, although it’s likely that sections of this code are used in the more recent version.
