The controller of a botnet is able to direct the activities of these compromised computers through communication channels formed by standards-based network protocols , such as IRC and Hypertext Transfer Protocol HTTP. Botnets are increasingly rented out by cyber criminals as commodities for a variety of purposes. Botnet architecture has evolved over time in an effort to evade detection and disruption.
