Question

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?

  • ASoC
  • BICS
  • CIoT

Why each option

The exploited refrigerator, used to send outbound packets as part of a botnet DDoS attack, belongs to the Internet of Things (IoT) category because it is an internet-connected consumer appliance.

ASoC

SoC (System on a Chip) is a specific type of integrated circuit that integrates all components of a computer or electronic system into a single chip, which is a component of a device, not a category for the entire networked appliance.

BICS

ICS (Industrial Control Systems) refers to systems used in industrial environments for controlling processes (e.g., SCADA, DCS), which consumer refrigerators are not part of.

CIoTCorrect

Refrigerators capable of sending outbound packets over the internet are characteristic examples of Internet of Things (IoT) devices. IoT devices are physical objects embedded with sensors and software that enable them to connect and exchange data with other systems over the internet, making them potential targets for exploitation in botnet attacks if not properly secured.

DMFD

MFD (Multi-Function Device) typically refers to office equipment such as printers, scanners, copiers, and fax machines combined into one unit, which a refrigerator is not.
