Exploit Hardware/Firmware Corruption - EX-0005

The adversary achieves execution or effect beneath the software stack, in device firmware, programmable logic, or the hardware itself, either by corrupting that layer or by driving it through interfaces that function exactly as designed. Examples include tampering with firmware images or configuration blobs burned into non-volatile memory; targeting MCU/SoC boot ROM fallbacks; editing FPGA bitstreams or partial-reconfiguration frames; leveraging physical phenomena and timing to flip bits or skip checks; or issuing legitimate low-level device, maintenance, and calibration commands that act directly on hardware without passing through high-level command mediation. Because these actions occur below or alongside the operating system and application FSW, traditional endpoint safeguards see normal interfaces while trust anchors are already altered.
