New hardware attack (TEE.fail) breaks modern secure enclaves
🔒 A new low-cost hardware-assisted attack called TEE.fail undermines current trusted execution environments from major chipmakers. The method inserts a tiny device between a memory module and the motherboard and requires a compromised OS kernel to extract secrets, defeating protections in Confidential Compute, SEV-SNP, and TDX/SDX. The attack completes in roughly three minutes and works against DDR5 memory, meaning the physical-access threats TEEs are designed to defend against are no longer reliably mitigated.
