What is the purpose of a keylogger?

The primary purpose of a keylogger is to monitor and record the keystrokes of a user. This software or hardware is designed to capture every keystroke made on a keyboard, which can then be analyzed later for various purposes, often malicious. Keyloggers are frequently used by cybercriminals to steal sensitive information such as usernames, passwords, credit card numbers, and other confidential data without the user's knowledge.

Understanding how keyloggers work is important in recognizing potential threats to personal security and data privacy. This awareness can help individuals and organizations implement strategies to protect against such threats, such as using antivirus software, ensuring regular updates, and practicing safe browsing habits.
