Keyloggers, also known as keystroke logging or simply keylogging, are a type of surveillance software or hardware designed to monitor and record every keystroke made on a computer or device. The primary purpose of a keylogger is to capture information typed by the user, including usernames, passwords, credit card numbers, personal messages, and any other sensitive data entered via the keyboard.

Keyloggers can be implemented in two main ways: software-based and hardware-based. Software keyloggers are programs installed on the target device, often disguised as legitimate applications or downloaded through malicious means like phishing emails or infected websites. They operate in the background, capturing keystrokes and often sending them to a remote attacker. Hardware keyloggers, on the other hand, are physical devices that are attached between the keyboard and the computer. These are less common for widespread attacks but can be used in targeted physical intrusions.

The uses of keyloggers range from legitimate security and monitoring purposes to malicious activities. For instance, employers might use them to monitor employee productivity or ensure data security. Parents might use them to monitor their children's online activities. However, keyloggers are predominantly used by cybercriminals for identity theft, financial fraud, and espionage. They are a significant threat to personal privacy and data security, as they can lead to compromised accounts and financial losses. Protecting against keyloggers involves using reputable antivirus software, being cautious about downloads and links, and enabling two-factor authentication where possible.
