Correct option is B
Keyloggers are malicious tools that record everything you type on your computer, including login names, passwords, and other sensitive information. They operate secretly and can exist as software or hardware devices. Keyloggers are often used by cybercriminals for data theft and unauthorized access.
Important Key Points:
- Keyloggers monitor and log keystrokes without the user’s knowledge.
- They are used for stealing personal information, financial details, and credentials.
- Anti-malware tools and vigilant cybersecurity practices are essential to detect and prevent keylogger attacks.
Knowledge Booster:
- Virus: A self-replicating program that infects files or systems but does not focus solely on keystroke logging.
- Worms: Malware that spreads across networks but does not log keystrokes.
- Ransomware: Encrypts files and demands payment for decryption, unrelated to keylogging.
