Keylogging, short for “keystroke logging” is the process of recording the keys struck on a keyboard, usually without the user’s knowledge.
Keyloggers can be implemented via hardware or software:
Hardware keyloggers intercept data at the physical level (e.g., between the keyboard and computer).
Software keyloggers, like LogKeys, capture keystrokes through the operating system.
This article explains how to use a popular open-source Linux keylogger called LogKeys for educational or testing purposes only. Unauthorized use of keyloggers to monitor someone else’s activity is unethical and illegal.
