keystroke logger

   Also found in: Wikipedia 0.01 sec.
keystroke logger
A program or hardware device that captures every key depression on the computer. Also known as "Keystroke Cops," they are used to monitor an employee's activities by recording every keystroke the user makes, including typos, backspacing and retyping.

A software-based keystroke logger can also be a Trojan that was installed clandestinely with the intent to steal passwords and confidential information. See snoopware and Trojan.

The KeyGhost Keystroke Logger
This unassuming device is attached between the keyboard cable and the socket on the back of the computer. It captures 500,000 bytes of whatever comes across the wire and requires no software on the computer it is monitoring. The contents are retrieved when connected to another computer.

And fourth, the more malicious types, like keystroke loggers, can even get installed by someone with direct physical access to your computer such as an employer, suspicious spouse, business competitor, or someone who wants to know exactly what you're doing.
However, some may use these keystroke loggers to spy on their co-workers and bosses.
Most anti-spyware software makers lump adware (that stuff which gets installed because it''s free or cheap), BHOs (browser helper objects - stuff that suddenly appears on your browser), distributed attack tools, keystroke loggers, PCP software, tracking cookies, and unauthorized remote admin tools in the same global spyware box.
