The making of an iOS 11 jailbreak: Kiddie to kernel hacker in 14 sleepless nights.

Presented at DerbyCon 8.0 Evolution (2018), Oct. 7, 2018, 11 a.m. (50 minutes).

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!
