faulTPM: Exposing AMD fTPMs' Deepest Secrets
Summary: The paper titled "faulTPM: Exposing AMD fTPMs' Deepest Secrets" by Hans Niklas Jacob and three other authors discusses a new class of attacks against firmware Trusted Platform Modules (fTPMs) used in modern security features. The authors experimentally verify this attack by compromising the AMD Secure Processor, which constitutes the Trusted Execution Environment (TEE) for AMD's fTPMs. This vulnerability exposes the complete internal TPM state of the fTPM, allowing attackers to extract any cryptographic material stored or sealed by the fTPM regardless of authentication mechanisms. The authors demonstrate the impact of their findings by enabling the first attack against Full Disk Encryption solutions backed by an fTPM and lay out how any application relying solely on the security properties of the TPM can be defeated by an attacker with 2-3 hours of physical access to the target device. The authors also analyze the impact of their attack on FDE solutions protected by a TPM and PIN strategy and find that when an f
