Intel and AMD trusted enclaves, the backbone of network security, fall to physical attacks
Intel and AMD's trusted enclaves, crucial for network security, have been vulnerable to physical attacks, compromising the confidentiality of data stored in the cloud. Researchers have exposed limitations in Intel's SGX and AMD's SEV-SNP protections, with attacks like Battering RAM allowing manipulation of encrypted data and Wiretap decrypting sensitive information. These attacks leverage deterministic encryption and a hardware interposer placed between the CPU and memory module to intercept data. The vulnerabilities highlight ongoing challenges in securing data within cloud environments.
