high-level IoT botnet explanation: Imagine you discovered a massive flaw in a robot vacuum/video doorbell/smart fridge/wi-fi connected blender/router/etc, where it would accept and execute any command you sent it. Next you come up with some way to discover and exploit as many of these devices as you can. It could be by finding all IP addresses of exposed devices via something like Shodan, or exploiting and taking over a centralized server that all these devices communicate with, or some other novel way. Anyways, once your in control of all these devices, you pick a target URL and send a command to all your devices to start CURLing a specific address over and over and over. Boom, you have a IoT botnet for DDoS attacks.
