Method and device for detecting and processing telecommunications fraud

Abstract

Embodiments of the present invention provide a telecommunications fraud detection and processing method and device. The method includes: obtaining information on multiple short messages sent by the phone number to be detected within the first preset time period; if it is determined that the URL carried in the short message matches the preset malicious website resource library, and the receipt of the short message After receiving the short message, the user terminal corresponding to the party's phone number accesses the URL carried in the short message, then regards the short message as an abnormal short message and determines the type of malicious website corresponding to the URL carried in the abnormal short message; according to at least one first characteristic parameter of the abnormal short message and Calculate the risk weight value of the malicious website type corresponding to the URL carried in the abnormal text message, and calculate the first characteristic value corresponding to the phone number to be detected; if it is judged that the first characteristic value is not less than the first preset threshold, the phone number to be detected is used as Telecom fraud number. The device is used to perform the above method. The method and device provided by the embodiments of the present invention improve the accuracy of telecommunications fraud detection.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for detecting and processing telecommunications fraud. Background technique [0002] The technology of telecommunications fraud is becoming more and more complex. It has evolved from the traditional use of changing the calling number to the use of means to collect user privacy, and then use text messages or calls to trick users into transferring money. Therefore, the research on telecommunications fraud detection methods is also more and more popular. focus on. [0003] Traditional telecommunications fraud analysis mostly uses the behavior of the calling user to discover the behavior of telecommunications fraud, which mainly includes the following methods: (1) According to the number to be verified extracted from the obtained suspect information, determine the number corresponding to the number to be verified. feature i...

AI Technical Summary

Problems solved by technology

However, most of the existing telecommunication frauds are first initiated through SMS and phishing websites, but the existing telecommunication fraud detection methods mostly analyze the calls of users, and cannot find SMS numbers and phishing websites in time, and because the specific fraud methods cannot be determined, And rely on manual analysis, which greatly affects the accuracy of telecommunications fraud detection
