What is the term for malware that provides attackers with full control by bypassing authentication and security measures?

• A. Rootkits
• B. Keyloggers
• C. Backdoor Trojans
• D. Worms

Answer: (C)

When malware creates a hidden, direct entry for an attacker to take control without re-authenticating, it’s a backdoor Trojan. This type of malware is designed to bypass normal security checks and login processes, opening a doorway that the attacker can use to remote-in, issue commands, install tools, exfiltrate data, and maintain access even as other defenses run. That ability to grant sustained, full control is what makes a backdoor Trojan the best description for this scenario. Rootkits are about hiding the malware and masquerading it within the system, not necessarily giving an attacker hands-on control. Keyloggers focus on recording keystrokes, not enabling full system access. Worms spread to other systems, but their primary trait is propagation, not providing a covert remote-control channel.
