keyloggning

Keylogging, also known as keystroke logging, is a type of surveillance that monitors and records every key struck on a keyboard, typically in a covert manner. This can be done through software or hardware. Software keyloggers are programs installed on a computer that capture keystrokes and often send them to a remote attacker. Hardware keyloggers are physical devices that can be attached to a keyboard cable or installed internally within the keyboard itself.

The primary purpose of keylogging is often malicious, aiming to steal sensitive information such as usernames, passwords, credit card numbers, and other personal data. This stolen information can then be used for identity theft, financial fraud, or unauthorized access to accounts. Keyloggers can be distributed through various means, including phishing emails, infected websites, or malicious software downloads.

While predominantly used for illicit purposes, keylogging can have legitimate applications. Employers may use it to monitor employee computer activity for security or productivity reasons, though this practice often requires employee consent and adherence to privacy laws. Parental control software might also incorporate keylogging features to monitor a child's online activity. However, the ethical and legal implications of keylogging vary significantly depending on the context and jurisdiction.
