The security code for Apple's mobile operating system was merged into the Github web service. Motherboard reports that this sink gave hackers the opportunity to jailbreak and hack devices on iOS.
What is known
The code is called iBoot, it is responsible for the process of trusted booting of the operating system. It verifies the kernel and checks to see if it has the necessary Apple signatures, and then passes it control or switches the device to recovery mode.
Unknown, who merged the code, said that iBoot refers to the release of iOS 9, but perhaps the part is also used in the 11 iteration of the OS. Fortunately for Apple, the hacker has laid out the code with missing files and will not be able to compile it.
The Greatest Leak in History
The author of a series of books about iOS and macOS Jonathan Levin told Motherboard that the iBoot fused to what he had to work with. Levin did not even dare to call this leak "the greatest in history."
The legitimacy of the code is still being tested, but Apple itself does not give comments. If everything proves to be true, this will be a real gift for jailbreak community, developers and intruders.
