What term describes a network of zombies/computers infected by a trojan?

• A. Botnet
• B. Worm Network
• C. Zombie Network
• D. Malware Farm

Answer: (A)

A botnet is a network of compromised computers under an attacker’s control. When malware such as a trojan infects machines, those hosts become bots (often called zombies) that can be instructed to perform coordinated tasks, like launching DDoS assaults, sending spam, or stealing data. The strength of a botnet lies in the scale and centralized control it enables, with all the infected devices acting as a single-enabled force. The other terms aren’t standard ways to describe this coordinated network: a worm-based network implies self-spreading software rather than controlled hosts; “zombie network” isn’t the conventional term for the collection; and “malware farm” isn’t used to describe this structure.
