Prototype iPhones That Hackers Use to Research Apple’s Most Sensitive Code

During Motherboard’s months-long investigation, I spoke to two dozen sources—security researchers, current and former Apple employees, rare phone collectors, and members of the iPhone jailbreaking scene—about the underground trade of dev-fused iPhones and their use in the iPhone hacking community.

At BlackHat, Solnik and his two former colleagues David Wang and Tarjei Mandt—also known as Planetbeing and Kernelpool in the iPhone jailbreaking community—blew the doors off the SEP with the impressive and technical talk, which delved into, for example, how the phone’s application processor and SEP communicate using a “secure mailbox,” the SEP’s “bootflow,” and the specific “opcodes” that Apple uses to read information from the processor. An independent iOS security researcher, who spoke on condition of anonymity in order not to damage his reputation within the jailbreaking community, said “Solnik was full of dev-fused [iPhones],” at the time of the SEP talk.
