Unbreaking the iPhone: Bootchain Reversal, SEP Sabotage, and the iOS Kernel Frontier
2025-09-25 , Off-Main Track

Everyone thinks iOS is unbreakable. This talk disagrees.

In Unbreaking the iPhone, we’ll dissect the invisible scaffolding behind Apple’s mobile empire. From Secure Enclave architecture to KTRR and PAC. We’ll explore how researchers theorize paths to reverse bootchain security, defeat SEP isolation, and repurpose GPU driver vulnerabilities for kernel access —even on post-checkm8 devices.

This isn’t a jailbreak tutorial, it’s a blueprint for those aiming to reach the highest levels of mobile OS exploitation.
