DDROP: Adapter plug bypasses Confidential Computing
TL;DR
AI-generated
IT researchers developed an adapter plug named DDROP that bypasses RAM encryption for Confidential Computing. This allows compromising virtual machines by preventing write access to DDR5 RAM, enabling the reading of old data. Processors like Intel TDX and AMD SEV-SNP are affected, with manufacturers classifying this as a physical attack outside their current threat model.
