Apple has since requested GitHub take down the code under a copyright claim, but it’s likely that the code has been stored and shared widely online in the hours it was available. As Motherboard points out, this same code was posted on Reddit in September, but it went effectively unnoticed.

For the average user who updates their software regularly, there’s likely little to be overly concerned about. The software is two years out of date, and even if hackers were able to use this code to engineer a way into a phone, it’s likely they’d still need physical access to your phone to do so.

Apple said, “old source code from three years ago appears to have been leaked, but by design the security of our products doesn’t depend on the secrecy of our source code. There are many layers of hardware and software protections built into our products, and we always encourage customers to update to the newest software releases to benefit from the latest protections.”

So: Make sure you keep your software up-to-date.
