AMD's Secure Encrypted Virtualization (SEV) is a cutting-edge technology that protects privacy and trust in cloud computing by encrypting a virtual machine's (VM's) memory and isolating it from advanced attackers, even those compromising critical infrastructure like the virtual machine manager or firmware.
We found that tampering with the embedded SPD chip on commercial DRAM modules allows attackers to bypass SEV protections - including AMD's latest SEV-SNP version.
