All Apple firmware hacked. Knowledge was made public in January. Can't find it in my search history at the moment, but will look into it later. I believe ZeroHedge reported this; it was quite big news at the time in the tech scene. Apple's stocks dove a bit after this came out, which was around the same time they loss the lawsuit for the biometrics in their apple watches (the pulse ox/heartbeat tracking features) for patent/copyright infringements from the medical industry.
