What term describes a coordinated group of infected systems used to perform large-scale attacks?

• A. Drone army
• B. Phantom cloud
• C. Botnet
• D. Bot cluster

Answer: (C)

A botnet is a network of compromised devices that are under the control of a single attacker to carry out large-scale actions. Each infected device becomes a bot (or zombie) and can be remotely commanded through a centralized infrastructure, enabling coordinated tasks like distributed denial-of-service (DDoS) attacks, mass spamming, or data theft. The strength of a botnet lies in its scale and the ability to orchestrate many machines at once from one control point, which is exactly what a coordinated group of infected systems describes. The other terms aren’t the standard terminology for this phenomenon in cybersecurity, so they don’t capture the established concept of a controlled, scalable network of bots.
