In December 2017,Google Project 0’s Ian Beer released an exploit for two iOS kernel bugs. This is Bryce’s story of going from being a iOS kernel n00b to weaponizing the exploit into a fully functioning jailbreak for iOS 11.1.2. Each challenge along the path will be discussed including: iOS sandboxing, the terrible AMFI, the intricacies of code signing & entitlements, sleep deprivation, and more. Everyone & all skill levels are welcome—kernel hacking isn’t that scary!
