Trigon: developing a deterministic iOS kernel exploit
Alfie
Cellebrite Labs
Abstract
Public iOS kernel exploitation has taken a turn for the worse over the past few years. Trigon is the second publicly-available exploit for iOS 16, based on an extremely powerful vulnerability in the XNU kernel. This talk will discuss how an exploit was developed for all of Apple’s arm64(e) SoCs, the various strategies used for each one and the obstacles and mitigations that made exploitation so difficult.
