Motherboard is out today with a follow-up on how Apple’s iBoot source code was leaked. While Apple has responded that it’s not an issue for the security of current products, some believe it could still be important in finding new vulnerability and bugs in iOS. Here’s the latest on how it all happened.

Motherboard looked more into how the iOS source code was leaked. It corroborated information from two sources claiming that they had been given the iBoot code by a low-level Apple employee in 2016, who the publication was unable to speak with.

While many might imagine a disgruntled employee, Motherboard reports that wasn’t necessarily the case.

The anonymous sources say that they were part of a group of five individuals who were given the leaked iBoot code. There weren’t any plans to widely share the information initially, but was naturally spread later on.

While the leak just gained mainstream attention this week, the code has been floating around for a while.
