New DDRop Attack Breaks Intel TDX and AMD SEV-SNP Confidential Computing

Researchers have disclosed a new hardware attack, called DDRop , that breaks the memory protection in Intel and AMD confidential computing by silently dropping writes to a server's memory, so the processor keeps reading old encrypted data as if it were current. The attack requires an attacker who...
