The development and application of blockchain technology makes it possible to build a more robust and flexible botnet command and control channel.In order to better study this type of potential new botnet threats, a highly confrontational botnet model based on blockchain smart contracts-SCBot was proposed.The SCBot model adopts a hierarchical hybrid topology structure, builds a command transmission channel based on smart contracts at the zombie subnet layer, and establishes a credibility evaluation mechanism to determine the authenticity of nodes, and enhances the confrontation of the network from the two major levels of traffic and terminals.The construction of small botnet clusters were simulated, comparative experiments on SCBot's command transmission efficiency and robustness were conducted, and its feasibility in the real environment from the perspective of economic costs was analyzed.Finally, a brief analysis and discussion of the defense strategy of this type of botnet were given.

Key words: cyber security, botnet, command and control, blockchain, smart contract
