T1542.001 System Firmware — Attack Simulation

Adversaries may modify system firmware to persist on systems.The BIOS (Basic Input/Output System) and The Unified Extensible Firmware Interface (UEFI) or Extensible Firmware Interface (EFI) are examples of system firmware that operate as the software interface between the operating system and hardware of a computer. System firmware like BIOS and (U)EFI underly the functionality of a computer and may be modified by an adversary to perform or…
