Battering down the doors - this $50 hacking kit is enough to break Intel and AMD's toughest chip defenses, so be on your guard

A laptop with digitally inserted hack warnings around it.

• A $50 interposer can replay encrypted traffic and undermine enclave memory, experts claim
• Intel SGX and AMD SEV-SNP both fall to replay manipulation
• Hardware-level trade-offs favored scalability, leaving freshness and integrity unprotected

Academics from KU Leuven and the University of Birmingham have shown how a simple interposer can undermine the hardware protections of both Intel and AMD processors.
