A. Ransomware
B. Spyware
C. Rootkit
D. Keylogger
E. Trojan
Answer
D. Keylogger
Explanation
A keylogger records keystrokes to capture sensitive information such as passwords and personal data.
The malware that secretly records a victim’s keystrokes is called a keylogger.
A keylogger is a type of malicious software (malware) designed to monitor and record every keystroke a user makes on their computer or mobile device.
Keyloggers can be delivered through phishing emails, malicious downloads, drive-by downloads from compromised websites, or even physical access to install hardware keyloggers.
Once installed, a keylogger captures sensitive information such as passwords, credit card numbers, personal messages, and other confidential data, then transmits this information to the attacker for malicious use.
Keyloggers are a form of spyware and are considered one of the highest-ranking global malware threats due to their effectiveness in stealing credentials and sensitive information.
While some keyloggers have legitimate monitoring uses, when used maliciously, they pose a significant risk to both individuals and organizations by enabling identity theft, financial fraud, and unauthorized access to secure systems.
A keylogger records keystrokes to capture sensitive information such as passwords and personal data, making it a critical threat in cybersecurity.
