Which of the following emerging technologies is frequently used for botnet distributed denial of service (DDoS) attacks?

Internet of Things (IoT) devices are frequently targeted and compromised due to their often weak security, becoming components of large botnets (like Mirai) used to launch powerful Distributed Denial of Service (DDoS) attacks against various targets.

Quantum computing is an emerging technology, but its primary current threat relates to breaking cryptographic algorithms, not directly facilitating DDoS botnets.

Virtual reality (VR) is focused on immersive experiences and does not inherently offer capabilities for orchestrating DDoS attacks.

Machine learning can be used in cybersecurity for both defense and offense, but it is not the technology that forms the backbone of the botnets themselves for DDoS attacks.
