As reported by Motherboard, certain "key" iOS source code was recently published on Github for the world to see. But it gives visibility into what the code does so anyone looking to reverse engineer iOS and write exploits can use this to make their job much easier.
Critical, top secret Apple code for the iPhone's operating system was posted on Github, opening a new, risky avenue for hackers and jailbreakers to access the device, Motherboard reported. The leaked code could also allow programmers to imitate iOS on platforms that are not related to Apple.
Apple seems to be having a pretty bad day, as critical iOS code was leaked to Github, giving hackers a deeper look at the inner workings of Apple's closed garden.
It's not clear just how big of a leak this is, but according to author Jonathan Levin, who has written book about iOS and OS X, said it's "the biggest leak in history", adding that it's "a huge deal". Report from Motherboard suggests that the code was available for retrieval by anyone for hours until Apple filed a copyright takedown request with GitHub and forced the site to remove the code. These types of jailbreaks used to be common on older versions of iOS, but as Apple has increased the security of their operating system with features such as the Secure Enclave Process chip, it's been more and more hard to unlock phones in this manner.
Though iPhone users are not at immediate risk following the leak, security experts have warned that hackers could develop ways to recreate the code and alter it for their own malicious purposes in the future. Grosfield said. "Apple will be scrambling to mitigate any potential risks, and the window of opportunity for malware to take advantage of that is probably pretty small".
Apple has been pretty secretive with its codes and has avoided releasing it to the public, although it has made certain parts of iOS and MacOS open source in the past few years.
Apple hasn't yet responded to news of the leak yet.
It is very likely that the code may have been spotted and was circulating in the jailbreaking and hacking community.
