Putting It All Together - Building an iOS Jailbreak from Scratch

Embark on a comprehensive journey through the intricate process of building a semi-untethered iOS jailbreak from scratch in this 24-minute conference talk from NULLCON 2020. Delve into the mysterious world of iOS jailbreaks as security researcher Umang Raghuvanshi lifts the curtain on their inner workings. Learn how to exploit memory corruption vulnerabilities, defeat Kernel Address Space Layout Randomisation, escape the iOS sandbox, remount the root filesystem, and bypass code signing and library validation to inject code into other processes. Discover groundbreaking techniques for achieving these feats on the latest Apple devices without bypassing ARMv8.3's Pointer Authentication. Gain valuable insights from Raghuvanshi, a member of the Electra jailbreak team and an expert in iOS kernel and browser exploitation, as he shares his expertise in this illuminating presentation.
