Problems solved by technology

[0004] However, because the first type of scheme adopts the method of manual review, the quality of the review depends on the professionalism of the reviewers, so the accuracy has relatively large limitations; Very long lag, unable to guarantee timely and effective URL identification
Although the second type of scheme can effectively identify websites with obvious keyword characteristics such as pornography and gambling, it is difficult to automatically identify false information released by hackers.
Therefore, the detection efficiency of existing malicious website detection technology is low

Abstract

The invention provides a method for detecting a malicious website. The method comprises the steps that a target webpage pointed to by a target web address of a target website to which a user has access is acquired, and a contact way in the target webpage is extracted; a malicious contact way database is searched for target information data matched with the contact way in the target webpage, wherein information data determined as a malicious contact way are stored in the malicious contact way database; when the target information data matched with the contact way in the target webpage are acquired, the target website is determined as the malicious website, and the target website is written into a malicious web address database. In addition, the invention provides a device for detecting the malicious website. According to the method and device for detecting the malicious website, the efficiency of detecting the malicious website can be improved.

Description

technical field [0001] The invention relates to computer technology, in particular to a malicious website detection method and device. Background technique [0002] The rapid development of Internet technology has brought more and more convenience to people's life. Through the Internet, people can conveniently share and download various materials, obtain various important information, and pay bills online. At the same time, the security situation of the Internet is not optimistic. Various types of Trojan horse viruses pretend to be normal files and spread wantonly, and phishing websites imitating normal websites to steal user account passwords are intensifying. [0003] In the prior art, there are usually two schemes for identifying and combating malicious websites: one is based on user reporting and manual review, such as PhishTank (http: / / www.phishtank.com / ), users can Submit a suspicious Uniform Resource Locator (UniformResourceLocator, URL), which will be added to Phis...
