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
