New WireTap Attack Extracts Intel SGX ECDSA Key via DDR4 Memory-Bus Interposer

In yet another piece of research, academics from Georgia Institute of Technology and Purdue University have demonstrated that the security guarantees offered by Intel's Software Guard eXtensions (SGX) can be bypassed on DDR4 systems to passively decrypt sensitive data.
SGX is designed as a hardware feature in Intel server processors that allows applications to be run in a Trusted Execution

Wow. If SGX can be broken via a memory-bus interposer, hardware-based enclaves are not as bulletproof as we thought.

Seems like nothing is bulletproof nowadays

Physical side channel attacks are back, and this is high level stuff.
