Which hardware keystroke capture device is commonly referred to as KeyGrabber?

• A. Spyware Propagation
• B. Desktop Spyware
• C. Email Spyware
• D. KeyGrabber

Answer: (D)

KeyGrabber refers to a hardware keylogger, a device that sits between the keyboard and the computer to capture keystrokes at the hardware level. It logs every key pressed, often without relying on the operating system or installed software, which makes it effective even if security measures try to hide software-based monitoring. The term is commonly used in security contexts to denote these physical devices that capture input directly from the keyboard signals.

The other options describe software-focused spyware categories and do not designate a hardware keystroke capture device, so they don’t fit as the hardware keylogger known as KeyGrabber.
