Mobile phone malware early warning method and device

Abstract

The embodiment of the invention provides a mobile phone malware pre-warning method and a mobile phone malware pre-warning device. The method comprises the steps of acquiring abnormal behavior features of a user terminal in an area to be monitored, and computing occurrence probability of each type of abnormal behavior features in the area to be monitored, wherein the abnormal behavior feature comprises any one or any combination of accessing bad websites, sending bad short and multimedia messages, and being abnormal in short message frequency, Internet surfing traffic and voice ticket discrete degree of short messages; computing transmission probability of mobile phone malware according to the occurrence probability and a behavior feature relation probability model; comparing a preset probability threshold in the behavior feature relation probability model, and deciding whether to pre-warn about the mobile phone malware. The device is used for executing the method. According to the method and the device provided by the embodiment of the invention, the occurrence possibility of the transmission event of the mobile phone malware is predicted according to the occurrence probability of the abnormal behavior features of the user terminal, prediction and pre-warning of transmission of the mobile phone malware is achieved, and detection timeliness of the mobile phone malware is improved.
