What term describes a malware program that enables attackers to gain administrative-level access to a device?

• A. Rootkits
• B. Trojan
• C. Ransomware
• D. Keylogger

Answer: (A)

Rootkits are malware designed to grant attackers administrative or root privileges while hiding their presence on the system. The key idea is not just performing malicious actions, but doing so at the highest level of access and remaining undetected by security tools. Once a rootkit gains this elevated access, it can manipulate OS components, install backdoors, and persist across reboots, which is what enables full control over the device without easy detection.

A Trojan, while it can enable harmful actions, relies on deceiving the user to run it and doesn’t inherently imply ongoing admin-level access. Ransomware focuses on encrypting files to extort payment rather than providing continued privileged control. A keylogger records keystrokes to capture sensitive input but does not by itself grant administrator-level access.
