This hunt targets the presence of known Mirai botnet command-and-control URLs, indicating that an adversary is actively managing compromised IoT or embedded devices within the network. Proactively hunting for these indicators in Azure Sentinel allows the SOC to identify silent botnet activity and isolate affected assets before they are leveraged for large-scale DDoS attacks or lateral movement.
