Which type of attack is commonly used to disrupt services and can be launched via IoT devices?

• A. MITM attacks
• B. Phishing
• C. Data Exfiltration
• D. DoS attacks

Answer: (D)

Denial of Service focuses on making a service unavailable by overwhelming it with traffic or requests, exhausting bandwidth, CPU, or memory resources. IoT devices, often insecure and easy to compromise, can be recruited into a botnet and commanded to flood a target with traffic. That collective load from many devices can cripple a service, which is exactly why this attack is commonly associated with IoT ecosystems and often manifests as a distributed denial of service. The other options involve intercepting communications, tricking users, or stealing data, not just disrupting availability, so they don’t fit the scenario described.
