Hunt Hypothesis

This detection identifies network traffic accessing known Mirai botnet command-and-control or infection URLs to uncover potential IoT device compromise and lateral movement within the environment. Proactively hunting for these indicators in Azure Sentinel is critical because Mirai variants can rapidly propagate across vulnerable devices, enabling adversaries to establish persistent footholds and launch large-scale DDoS attacks before traditional signatures trigger alerts.
