SkyNET project

SkyNET is a stealth network that connects hosts to a botmaster through a mobile drone. The network is comprised of machines on home Wi-Fi networks in a proximal urban area, and one or more autonomous attack drones. The SkyNET is used by a botmaster to command their botnet(s) without using the Internet. The drones are programmed to scour an urban area and compromise wireless networks. Once compromised, the drone attacks the local hosts. When a host is compromised it joins both the Internet-facing botnet, and the sun-facing SkyNET. Subsequent drone flights are used to issue command and control without ever linking the botmaster to the botnet via the Internet. Reverse engineering the botnet, or enumerating the bots, does not reveal the identity of the botmaster. An analyst is forced to observe the autonomous attack drone to bridge the command and control gap. In this paper we present a working example, SkyNET complete with a prototype attack drone, discuss the reality of using such a command and control method, and provide insight on how to prevent against such attacks.
