Keyloggers

Keyloggers are a form of surveillance software, either hardware or software, designed to record every keystroke made on a computer or other electronic device. This captured data often includes passwords, credit card numbers, private messages, and browsing history. They can be used for legitimate purposes, such as monitoring employee productivity or parental control, but are frequently used maliciously to steal sensitive information or gain unauthorized access to systems. The effectiveness of keyloggers depends on their stealth and the security measures in place to detect them. keyloggers often operate invisibly in the background.
