CompTIA Security+ (SY0-501) — Question 2

A botnet has hit a popular website with a massive number of GRE-encapsulated packets to perform a DDoS attack. News outlets discover a certain type of refrigerator was exploited and used to send outbound packets to the website that crashed. To which of the following categories does the refrigerator belong?

Answer options

• A. SoC
• B. ICS
• C. IoT
• D. MFD

Correct answer: C

Explanation

The refrigerator is categorized as IoT (Internet of Things) because it is a smart device connected to the internet and capable of sending and receiving data. SoC (System on Chip) refers to integrated circuits, ICS (Industrial Control Systems) relates to systems used in industrial environments, and MFD (Multi-Function Device) typically pertains to devices like printers and copiers, which do not apply in this context.
