The article surveys a series of concerning attacks on Trusted Execution Environments (TEEs) including Intel SGX and AMD SEV, arguing that TEE security claims are tenuous due to CPU complexity and side-channel vulnerabilities. Attacks span from Foreshadow (2018) through WireTap.fail (2025), showing a persistent pattern of attestation key theft and remote attestation forgery. The author urges reconsidering TEE deployment strategies.
Background
Trusted Execution Environments like Intel SGX and AMD SEV aim to protect sensitive computations from host OS and physical attackers, but a growing number of attacks have undermined their security guarantees since 2018.
