What type of software allows a hacker to gain near total control of a computer while hiding its presence from the user and standard detection methods?

• A. Backdoors
• B. Rootkits
• C. Spyware
• D. Worms

Answer: (B)

Rootkits are designed to give an attacker near-total control of a machine while concealing their presence from both the user and standard security tools. They achieve this by operating at a low level—often kernel or boot level—and by manipulating or hiding key system components such as files, processes, and network connections. This stealth lets the attacker maintain persistent access, run commands, install additional tools, and exfiltrate data without easy detection. Backdoors provide hidden access points, but they don’t inherently hide themselves from detection by security measures. Spyware focuses on silently monitoring the user and collecting data rather than granting full control. Worms are primarily about self-replication and spreading across networks, not about staying hidden while giving continual control over a single host.
