This detection identifies adversary activity where IoT devices or network hosts access known Mirai botnet command-and-control URLs to establish initial infection and potential lateral movement. Proactive hunting for these specific URLs in Azure Sentinel is critical because Mirai variants frequently target unpatched infrastructure, enabling early disruption of large-scale DDoS campaigns before they compromise broader organizational assets.
