Abstract

The invention discloses a network fraud detection method and a device thereof, electronic equipment and a storage medium. The method comprises the following steps: acquiring historical network interaction data of a victim in the case process in a target network fraud case, wherein the target network fraud case is a long-time multi-online interaction type fraud case; performing feature extraction on the historical network interaction data of each target network fraud case to form a website feature information base matched with at least one historical fraud website; acquiring network access data of at least one monitoring user in the monitoring time interval; and comparing the network access data with a website feature information base, and detecting suspected victim users whose number of times of accessing suspected fraud websites in a monitoring time interval exceeds a set threshold value; wherein the website feature information of the suspected fraud website and the website feature information of the historical fraud website meet preset similar conditions. According to the method, fraud cases can be identified in advance, so that the occurrence probability of the fraud cases is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information security, and in particular, to a network fraud detection method, device, electronic equipment, and storage medium. Background technique [0002] With the development of the Internet and information technology, the means of fraud cases have gradually developed from traditional telephone fraud to new Internet fraud, which has brought great economic losses to Internet users. [0003] At present, in Internet fraud cases, it is usually only after the victim reports the crime that he can learn the details of the fraud based on the information provided by the victim. It is impossible to identify fraud in advance technically, reduce the probability of fraud incidents, and protect the property safety of Internet users. Contents of the invention [0004] Embodiments of the present invention provide a network fraud detection method, device, electronic equipment, and storage ...
