Turn off physical interfaces (like USB or thunderbolt DMA access) in the BIOS if they are not required.
The Basic Input/Output System (BIOS) and its modern successor, the Unified Extensible Firmware Interface (UEFI), represent the most foundational software layer of a computer. Securing it is paramount because code executing at this level operates with the highest possible privileges, often invisible to the operating system and standard security software. 🛡️ The Foundation: Understanding BIOS/UEFI Attacking and Defending BIOS
Attackers use clips to connect directly to the SPI flash chip on the motherboard to read or overwrite the BIOS binary. Turn off physical interfaces (like USB or thunderbolt
