Intel and AMD trusted enclaves, the backbone of network security, fall to physical attacks

The key benefit of Battering RAM is that it requires equipment that costs less than $50 to pull off. It also allows active decryption, meaning encrypted data can be both read and tampered with. In addition, it works against both SGX and SEV-SNP, as long as they work with DDR4 memory modules. Wiretap Wiretap, meanwhile,… Read More: Intel and AMD trusted enclaves, the backbone of network security,… »

AMD’s trusted execution environment blown wide open by new BadRAM attack

If a VM has been backdoored, the cryptographic attestation will fail and immediately alert the VM admin of the compromise. Or at least that’s how SEV-SNP is designed to work. BadRAM is an attack that a server admin can carry out in minutes, using either about $10 of hardware, or in some cases, software only,… Read More: AMD’s trusted execution environment blown wide open by new BadRAM… »
