What is a Keylogger?

A keylogger builds a log of everything typed into a keyboard to be reviewed by a third party. Keyloggers can be used for legitimate purposes to troubleshoot networks, analyze employee productivity, or to assist law enforcement, for example; or they can be used for illegitimate purposes to surreptitiously spy on people for personal gain. A keylogger can be a hardware device or a software program.

The most common hardware keylogger plugs into the computer’s keyboard port, connecting to the keyboard cable. It can look like an extension tail or in other cases a small cylindrical device. This makes it easy to spot, if looked for, but it won’t be detectable by software. Models are priced around the number of keystrokes they can hold, with higher capacities being more expensive. One entry model costs $49 US Dollars (USD) with a capacity of 128,000 keystrokes.
