What is a key feature of hardware keyloggers?

• A. They record keystrokes and are wirelessly connected
• B. They are hidden inside the computer's hardware
• C. They are undetectable by standard antivirus software
• D. They are placed on a keyboard plug between the keyboard and USB socket

Answer: (D)

A fundamental characteristic of hardware keyloggers is that they are typically installed externally between the keyboard and the computer's USB socket. This positioning allows them to capture every keystroke made by the user without modifying internal software or systems. When a user types, the keystrokes pass through the keylogger before reaching the computer, enabling the device to record the data. This physical placement makes it challenging for the device to be easily detected by software-based monitoring tools, including antivirus programs, because they do not interact with the computer's software environment. In contrast to options that describe wireless connectivity or internal placement within the hardware, the defining feature of hardware keyloggers is their ability to intercept and log keystrokes through this strategic placement in the connection chain.
