Overview
Adversaries can also search for undocumented bits on a hardware device, commonly known as "chicken bits". These bits are used to enable/disable certain functionality, but are not published. Adversaries can reverse engineer firmware to identify hidden features and change these bits at runtime to achieve malicious behavior.
