What is a keylogger?

A keylogger is specifically a type of software designed to record keystrokes made by a user. This recording can include everything typed on a keyboard, such as usernames, passwords, messages, and other sensitive information. Keyloggers are often employed for malicious purposes, such as stealing personal data or unauthorized access to accounts. Their ability to discreetly monitor user input without consent makes them powerful tools in the arsenal of cybercriminals.

While other choices present different types of software or devices that serve legitimate purposes, they do not accurately describe the primary function of a keylogger. For example, capturing network packets is related to network traffic analysis, securing passwords involves encryption and access control measures, and time tracking applications are focused on monitoring time spent on tasks. The definition of a keylogger as software that captures and logs keystrokes distinguishes it as a specialized tool often associated with malicious intent.
