Which term describes software designed to be controlled remotely to perform tasks automatically?

• A. Hack Value
• B. Worm
• C. Payload
• D. Bot

Answer: (D)

A bot is software designed to be controlled remotely to perform tasks automatically. Bots wait for commands from a controller—often through a centralized command-and-control channel—and then carry out actions across infected machines without user interaction. This setup is common in botnets, where many bots are coordinated to perform tasks such as DDoS attacks, data theft, or spamming.

Worms, on the other hand, focus on self-propagation across networks rather than centralized remote control for automated tasks. A payload is the malicious code that executes a harmful action, but it isn’t defined by remote control itself. Hack value isn’t a standard term in this context.
