2/2 Its legacy however lives on, being the first demonstration of an end-to-end TDX break. Other CPUs have already risen to take its role, with the server being operational by simply plopping a fresh CPU from the tray. This one however is going to a cherished place on the shelf.
1/2 After two weeks of TEE.fail being public (and additional 6+ month of private disclosure) Intel has finally revoked one of several CPUs used for @TeeDotFail. This means that the Xeon chip below has made the ultimate sacrifice and will never run SGX or TDX again.

More interposer fun, this time with DDR5 memory. Breaking TDX, SGX, SEV and even Nvidia TEEs. Checkout our work at TEE.fail, and get a personally-signed Intel attestation report at @TeeDotFail.
Want to know what happens when commercial TEEs meet improvised DRAM memory interposers? SGX mayhem including attestation key extraction. Please DO try that at home😉. Check out our work at wiretap.fail
