To this date P2P overlays remain a popular choice for botnet command and control. With the rise of recent IoT botnets, we aimed to monitor multiple IoT P2P botnets at the same time, to compare them against each other and traditional Windows based P2P botnets. During this process we came across several challenges and insights in scaling and maintaining multiple monitoring operations simultaneously. In this talk we want to share our insights and introduce the Botnet Monitoring System, a tool to reduce redundancy and enable collaboration for P2P botnet monitoring.
