The implication from the company is that even if the very latest version of the source code leaked, it would still not be represent a security threat, and this was further reduced by the age of the code.
It could provide hackers with a treasure trove of information they could use to design new attacks against Apple's operating system iOS.
However, Apple has now released a statement to address the growing unease of its customers worldwide.
One of Apple's most guarded secrets has reportedly been leaked online by an anonymous source. Github was quick to comply with the request, and removed the iOS source code post from the repository of the user. Nearly all iPhone users are safe from any potential hacking borne from this leak, but even then, Apple still recommends keeping your OS updated.
Ninety-three percent of users have downloaded iOS 10 or later, and 65 percent have downloaded iOS 11, which includes the latest protections, according to the company.
The code has seemingly been taken from the "iBoot" part of the iOS, the part of the computer that begins to boot the operating system when it is turned on.
Motherboard asked Jonathan Levin - chief technology officer of software security firm Technologeeks and author of several books on the theme - what he thinks about the leak. According to Motherboard, a source at Apple claims that the company was already aware of the leak before it made it to GitHub, which would make sense, since it seems to have been passed around the jailbreaking community for some time already.
What makes this is so interesting - and potentially frightening - is that security researchers and hackers alike will scan through the code to try and find inherent flaws in it. "It is not open-source".
Since the code that was leaked handles loading the OS, the bugs can be used for anything from enabling jailbreaks to loading something prior to the OS, Gorenc noted.
Levin subsequently denied that he used that expression in a tweet, while Apple did not respond to Business Insider's request for comment.
