Abstract

The invention discloses an abnormal account detection method and device. The method comprises the steps of obtaining a to-be-analyzed sample data set; obtaining associated account information and equipment information from the sample data set; obtaining identification information of equipment from the equipment information, and establishing a complex network between the identification informationof the equipment and accounts associated with the identification information according to the equipment information; carrying out community mining on the complex network according to a preset community mining algorithm, thereby obtaining a plurality of community clusters, wherein each community cluster comprises a plurality of associated account nodes; and extracting target community clusters of which number of account nodes is greater than a preset threshold from all community clusters, and determining accounts contained in the target community clusters as abnormal accounts. The problem thatin the prior art, a conventional abnormal account identification method is liable to lose efficacy is solved, and the purpose of relatively comprehensively and deeply identifying the abnormal accountsare realized.
