Oops! I Glitched It Again - How to Multi-Glitch the Glitching-Protections on ARM TrustZone-M

Explore the world of Fault Injection (FI) attacks, also known as Glitching, in this 36-minute Black Hat conference talk. Delve into the severe threat these attacks pose to real-world computing devices by injecting physical faults at runtime to alter target behavior. Learn about various countermeasures proposed to counteract different types of fault injection methods across abstraction layers, including modifications to underlying hardware and firmware at the machine instruction level. Gain insights from presenters Ahmad-Reza Sadeghi, Richard Mitev, and Marvin Saß as they discuss multi-glitching techniques specifically targeting glitching protections on ARM TrustZone-M architecture.
