This physical hardware attack exploits the memory path between processors and DDR5 modules to bypass confidentiality guarantees in Intel TDX and AMD SEV-SNP, revealing a critical vulnerability in cloud infrastructure trust boundaries. The technique relies on a custom interposer that silently discards specific write commands, allowing attackers with brief physical access to recover overwritten data from protected virtual machines. This development underscores the necessity of re-evaluating hardware-level security assumptions for confidential computing deployments where supply chain or maintenance access cannot be fully trusted.
