Short message discriminating method and device

Abstract

The invention discloses a short message discriminating method and device. The method comprises the following steps: acquiring a received short message; determining the short message as the suspiciousmalicious short message when judging that the short message meets a preset condition; matching the suspicious malicious short message with data in a preset malicious software data set to acquire a first matching result; judging whether the first matching result represents the successful matching; determining the suspicious malicious short message as the malicious short message if the first matching result represents the successful matching; or reporting the suspicious malicious short message to a monitoring system, and determining whether the suspicious malicious short message is the maliciousshort message based on a judgement result returned by the monitoring system. Therefore, the terminal can actively discriminate the short message without artificially analyzing the short message, andthe unknown malicious short message is discriminated by using the monitoring system, the time is saved, the efficiency and the accuracy rate are improved, the detection coverage range is enlarged, andthe convenience is provided for the user.

Description

technical field [0001] The invention relates to the field of smart technology, in particular to a method and device for distinguishing short messages. Background technique [0002] With the development of smart technology and the continuous development of application programs, the types and numbers of malicious application programs are also continuously increasing. Without the user's knowledge, malicious applications can automatically customize various services to generate malicious deductions, send mass spam messages, maliciously push advertisements, maliciously install applications, and steal and sell user privacy to make profits for illegal personnel. [0003] Malicious applications are usually spread through forums, software bundling, MMS, and text messages. Among them, SMS dissemination has become one of the main ways for malicious applications to spread. Malicious applications first steal user information without the user's knowledge, and then pretend to be acquaintan...
