Which term denotes a large network of compromised devices used to execute coordinated attacks?

• A. Jamming Attack
• B. Software Defined Radio Attack (SDR)
• C. IoT Hacking Information Gathering
• D. Army of Botnets

Answer: (D)

A botnet is a network of devices compromised by malware and controlled by an attacker to act in concert. When we talk about a large-scale setup used to execute coordinated attacks, the phrase “an army of botnets” captures that idea—many botnets working together to amplify power and reach, enabling massive DDoS campaigns, spam, or data theft. This best fits the description because it directly conveys a large, coordinated network of compromised devices. The other options describe different concepts: jamming attacks interfere with wireless signals, software defined radio attacks target SDR devices or software-radio vulnerabilities, and IoT hacking information gathering is about reconnaissance rather than executing a coordinated attack with a botnet.
