The invention provides a command-and-control (C&C) domain name analysis-based botnet detection method, device, apparatus and medium. The method includes an information acquisition step where DNS logs are acquired; a domain name analysis step where C&C domain names in the DNS logs are detected and the category of each C&C domain name is determined according to a pre-built domain name analyzer; a botnet determination step where whether a botnet exists is determined according to the C&C domain name and the category of C&C domain name. In the C&C domain name analysis-based botnet detection method, device, apparatus and medium provided by the present invention, by analyzing the domain name system (DNS) logs, the C&C domain name used in the attack activity is extracted for further analysis of the types of parasitic Trojans to thereby lock down the bot that the C&C server has controlled. In addition, the botnet activity trend can be analyzed by analyzing the Poisson parameter of each type of the C&C domain name, so as to form effective suppression measures in time.
