Hunt Hypothesis

This detection rule identifies network traffic connecting to known Mirai botnet command-and-control URLs, signaling potential IoT device compromise or lateral movement by adversaries leveraging this malware family. Proactive hunting for these indicators in Azure Sentinel is critical to rapidly isolate infected endpoints and prevent the propagation of large-scale DDoS attacks before they disrupt core infrastructure.
