The hypothesis is that the detected URLs are associated with Mirai botnet infrastructure, potentially used to compromise IoT devices and establish command and control channels. SOC teams should proactively hunt for these URLs in Azure Sentinel to identify and mitigate early-stage Mirai-related attacks before they lead to large-scale botnet activity.
