Threat Hunting for Beginners: Hunting C2 With DNS

DNS can be a valuable data source for identifying covert command-and-control (C2) activity. Attackers rely on it precisely because it's allowed out of nearly every network, including highly restricted environments.

This module is designed to help new threat hunters recognize patterns that suggest DNS is being used for malicious communication. We'll walk through several C2 techniques, show you what they look like in real data and help you build practical hunting strategies based on observable behaviors.

You don’t need deep knowledge or a background in malware analysis to get started—just an eye for anomalies and a willingness to dig.
