Which Trojan category is designed to form a botnet for carrying out DDoS attacks?

• A. IoT Trojans
• B. wrapper
• C. DDoS Trojans
• D. Mirai

Answer: (C)

The main idea here is a Trojan designed to build and control a botnet specifically for carrying out DDoS attacks. A DDoS Trojan includes the functionality to compromise multiple machines, enroll them into a botnet, and coordinate attack traffic, usually via a command-and-control channel, to overwhelm a target. That makes it the best fit for the category described. IoT Trojans target internet-connected devices more broadly and may be used for DDoS, but the category isn’t defined by the DDoS goal alone. A wrapper is a technique to conceal payloads, not a category focused on botnets or DDoS. Mirai is a notable IoT botnet malware, but it’s an example, not the category itself.
