Cheap Hardware Module Bypasses AMD, Intel Memory Encryption

Researchers from KU Leuven and UK universities disclosed "Battering RAM," a low-cost (~$50) interposer placed between CPU and DRAM that dynamically creates physical address aliases at runtime to bypass Intel/AMD confidential-computing memory encryption and exfiltrate or corrupt enclave data; the attack leverages removed integrity and freshness protections in modern designs and poses physical-access and supply-chain risks to cloud providers and customers.
