TEE.fail: Breaking Trusted Execution Environments via DDR5 Memory Bus Interposition

In this paper, the researchers show that the security guarantees of modern TEE offerings by Intel and AMD can be broken cheaply and easily, by building a memory interposition device that allows attackers to physically inspect all memory traffic inside a DDR5 server...

Compromising Trusted Execution Environments through DDR5 Memory Bus Interposition

Summary Researchers successfully executed a physical bus interposition attack targeting server-grade DDR5 memory, compromising the confidentiality of encrypted data during runtime. AMD does not plan to provide mitigations since physical vector attacks are out of scope for AMD SEV-SNP. as detailed...

WireTap: Breaking Server SGX via DRAM Bus Interposition

Whitepaper that delves into Intel’s Software Guard eXtension SGX. A common misconception is that physical attacks on SGX require expensive laboratory equipment, thus putting them out of reach of hobbyist-level attackers. In this work, the authors challenge this belief, showing how simple memory b...
