What is a keylogger and how does it work?
A keylogger is a type of malicious software (malware) that records every keystroke made on a computer or mobile device. It can capture sensitive information such as login credentials, credit card numbers, and personal data. Keyloggers can be hardware-based, software-based, or a combination of both. Hardware-based keyloggers are physical devices that connect to the computer, while software-based keyloggers are programs that run in the background.
Keyloggers work by monitoring keyboard input and logging every keystroke, including passwords, credit card numbers, and other sensitive information. They can also capture screenshots, log websites visited, and record chat conversations. The recorded data is then sent to the attacker, who can use it for malicious purposes such as identity theft, financial fraud, or blackmail. Keyloggers can be spread through phishing emails, infected software downloads, or exploited vulnerabilities in operating systems and applications.
How do keyloggers get installed on my device?
Keyloggers can get installed on your device through various means, including phishing emails, infected software downloads, and exploited vulnerabilities in operating systems and applications.
