GOD MODE UNLOCKED Hardware Backdoors in redacted x86
Christopher Domas presents god mode unlocked hardware backdoors in redacted x86: Complexity is increasing.
Summary
Architecture and Background
Complexity is increasing.
Vulnerability Analysis
Trust eroding.
Exploitation and Demonstrations
In the wake of Spectre and Meltdown, when it seems that things cannot get any darker for processor security, the last light goes out.
Remediation and Defensive Strategies
This talk will demonstrate what everyone has long feared but never proven: there are hardware backdoors in some x86 processors, and they're buried deeper than we ever imagined possible. While this research specifically examines a third-party processor, we use this as a stepping stone to explore the feasibility of more widespread hardware backdoors.
