Explore a critical security vulnerability in server platforms through this Black Hat conference talk. Delve into the overlooked attack surface of the PMBus, widely used on server motherboards for power monitoring and management. Learn how hardware-based attacks like voltage glitching, once a threat primarily to embedded processors, now pose significant risks to desktop and server processors. Examine recent attacks such as Clkscrew, Plundervolt, VoltJockey, and V0ltPwn that exploit built-in power management features to compromise trusted execution environments like Intel SGX and ARM TrustZone. Gain insights into the potential security implications of PMBus exploitation and understand the importance of addressing this vulnerability in server infrastructure security.
