What is the primary function of a Keystroke Logger?

The primary function of a keystroke logger is to log user keystrokes. This tool captures every keystroke made on a keyboard, allowing for the monitoring of user activity. It can record sensitive information, such as passwords and personal messages, which can be misused by attackers for unauthorized access or identity theft.

Keystroke loggers are often used in both legitimate contexts for monitoring employee activity and in malicious contexts for spying on users. Understanding this capability is crucial in cybersecurity since keystroke loggers can pose a significant threat to user privacy and data security.

The other functions mentioned, such as encrypting user files, monitoring network traffic, or executing logic bombs, do not accurately describe the primary role of a keystroke logger, which specifically focuses on the recording of keystroke data.
