A new research paper explains vulnerabilities in AMD SoCs that could let attackers neutralize any security from their TPM implementations. The attacks can expose any cryptographic information or other credentials TPM guards.
Trusted Platform Module (TPM) adds a layer of security to CPUs that cordons off sensitive information like encryption keys and credentials, making it harder for hackers to access them. In systems using the feature, it’s the mechanism behind PINs used to log in to Windows. Traditionally, TPM incorporates a physical chip on the motherboard, but many processors also incorporate a software-based version called firmware TPM (fTPM) that users can easily activate through the BIOS.
