Which term describes BIOS-level firmware capable of capturing keystrokes, requiring physical or admin access?

• A. PC/BIOS Embedded
• B. Keylogger Keyboard
• C. Hardware Keystroke Loggers
• D. RemoteExec

Answer: (A)

BIOS-level firmware capturing keystrokes is a firmware-based keylogger embedded in the PC’s BIOS/UEFI. This term fits because it describes code that lives in the system firmware, which operates before the operating system loads, making it possible to intercept keystrokes at a very early stage. Installing or modifying this kind of capability requires physical access or administrative privileges to flash or alter the BIOS, since firmware changes are privileged operations. Once in place, it can persist across OS installs and remain difficult to detect with standard software tools, because it’s not running within the OS. The other options describe different kinds of keylogging: a keyboard-based device, a general hardware logger, or a remote command tool, none of which specify firmware-level, BIOS-integrated capture.
