One Glitch to Rule Them All - Fault Injection Attacks Against the AMD Secure Processor

Explore a groundbreaking hardware attack against the AMD Secure Processor (AMD-SP) in this 33-minute Black Hat conference talk. Delve into the vulnerabilities of AMD CPUs' dedicated security coprocessor, which serves as the root of trust for modern AMD systems and supports critical security features like Secure Encrypted Virtualization (SEV) and firmware Trusted Platform Module (fTPM). Learn about fault injection techniques, voltage control methods, and the attack cycle used to gain code execution on AMD SPs across all Zen microarchitectures. Understand the implications of this attack on system security and discover the tools and analysis methods employed, including the PSP Tool and logic analyzer. Gain insights into the setup process, attack explanation, and the concept of SEBA (Single Event Bit Alteration) in this comprehensive exploration of AMD processor vulnerabilities.
