AMD secure VM tech undone by DRAM meddling

by

December 10, 2024 at 11:10AM Researchers revealed that AMD’s Secure Encrypted Virtualization (SEV) can be compromised using low-cost hardware. Their “BadRAM” attack exploits the SPD chip to bypass memory access restrictions. This vulnerability undermines SEV’s integrity and affects major cloud providers, prompting AMD to prepare an advisory and recommend securing SPD locks on memory modules. … Read more

New CacheWarp AMD CPU attack lets hackers gain root in Linux VMs

by

November 14, 2023 at 03:34PM CacheWarp, a new software-based fault injection attack, allows threat actors to hack into AMD SEV-protected virtual machines. The attack exploits vulnerabilities in AMD’s SEV-ES and SEV-SNP technology, designed to protect against malicious hypervisors. Malicious actors can manipulate memory writes to escalate privileges and gain remote code execution. Security researchers have … Read more
