The Command & Control (C2) network is the heart of any botnet. If you lose your command and control channel, then your bots are left in the wild with no way to reach them, stuck on their last instruction. In this talk we will explore ways to ensure that your command and control network is tolerant to changes and can adapt to servers being dynamically added to and removed from the network, as well as the organization of bots and how they connect to your C2 infrastructure.
