Botnets

Botnets are networks of computers infected by a botnet agent that are under hidden control of a third party. They are used to execute various commands ordered by the attacker. Most common uses of botnets are criminal operations that require distributed resources, such as DDoS attacks on selected targets, spam campaigns, and performing click fraud. Often, the botnet agent is ordered to download and install additional payloads or to steal data from the local computer.

From the moment of infection, botnet agents keep in touch with their remote Command-and-Control server (C&C). The communication can be carried by various means, and cybercriminals keep on inventing in new methods to hide their data transmission channels. There have been some unusual ways via social media like Twitter or reddit to send commands. However, the most common implementation of the C&C is a web-application, contacted by the client via simple HTTP requests.
