$50 Battering RAM Attack Breaks Intel and AMD Cloud Security Protections

A group of academics from KU Leuven and the University of Birmingham has demonstrated a new vulnerability called Battering RAM to bypass the latest defenses on Intel and AMD cloud processors.
“We built a simple, $50 interposer that sits quietly in the memory path, behaving transparently during startup and passing all trust checks,” researchers Jesse De Meulemeester, David Oswald, Ingrid
