Which hardware keylogger is a device that captures keystrokes from a PS/2 or USB keyboard?

• A. KeyGrabber
• B. Spyrix Keylogger Free
• C. Refog Mac Keylogger
• D. Desktop Spyware

Answer: (A)

Hardware keyloggers are physical devices that sit between the keyboard and the computer, intercepting and recording every keystroke without needing to install software on the target machine. Because they are inline hardware, they work directly with different keyboard interfaces, including PS/2 and USB, by capturing signals as the key presses pass through. That makes a device like KeyGrabber the correct choice, since it’s designed to be plugged into the keyboard line and log keystrokes locally, independent of the host operating system. The other options describe software solutions or generic terms rather than a physical inline device. Spyrix Keylogger Free and Refog Mac Keylogger are software-based keyloggers that require installation and operate within the OS. Desktop Spyware is a broad label and not a specific hardware device.
