What Does a Keylogger Do?

The term keylogger refers to software or hardware that monitors input on a computer or other device. A keylogger can be malicious software, but can have practical purposes as well.

Function

A keylogger monitors all input on a computer or other electronic device and records keystrokes. Sometimes a keylogger can record other details, like program lists and chat logs.

Types

Keyloggers can either be software or hardware. Software keyloggers are installed onto a machine and hardware keyloggers are physical devices plugged into the machine.

Effects

When a keylogger is present on a system, every keystroke is recorded and monitored, including password input and other private information.

Benefits

Keyloggers can be used by employers or system administrators to monitor computer activity on a network.

Misuse

Keyloggers can run silently in the background processes of a machine; hackers and other cyber criminals can use key loggers to steal valuable data from computers.

Tip

Most keyloggers are found and deleted by a standard anti-virus software. If you believe your computer is infected without your knowledge, run a virus scan.
