Overview
Explore the dark underbelly of processor security in this eye-opening conference talk from HITB Security Conference. Delve into the discovery of a privilege escalation backdoor in x86 CPUs that allows unprivileged users to bypass all security checks and escalate from ring 3 to ring 0. Witness a live demonstration of exploiting this deliberate manufacturer addition to gain root permissions, regardless of operating system or security measures. Examine the broader implications of this finding and its potential widespread nature across processor families. Learn about proposed detection and prevention methods for such backdoors. Gain access to open-source tools for discovering, exploiting, and patching these vulnerabilities. Leave with valuable insights on identifying, exploiting, and safeguarding against future hardware-level threats in processors.
