A keylogger is a hardware device that records the real time activity of a computer user including the keyboard keys they press.
Hardware keyloggers are used for keystroke logging, a method of capturing and recording computer users' keystrokes, including sensitive passwords. They are implemented via a device plugged inline between a computer keyboard and a computer. They log all keyboard activity to their internal memory.
