Embodiment Construction

[0045] The present invention provides a malicious webpage advertisement detection method based on the advertisement network topology, comprising the following steps:

[0046] Step 1, extracting all URLs in the website to be tested;

[0047] This step extracts URL information in the website to be tested, and URL grabbing software, such as the open source web crawler Nutch, can be used to obtain all URLs in the website to be tested. The principle of URL extraction is as follows figure 2 shown.

[0048] In this embodiment, all URLs in the website are crawled by improving the open source web crawler Nutch. A crawling process is as follows, and all URLs in the website can be obtained by repeated repetition. Call each URL crawled a node.

[0049] 1) The injection operation provides the initial data of the crawler operation, and submits the initial URL information to the Crawlerdb database.

[0050] 2) Generate operations to create grab lists. URLs are fetched from the databas...

Abstract

The invention discloses a malicious webpage advertising detection method based on advertising network topology. The method comprises the basic steps of extraction of all URL in websites to be detected, extraction of URL relevant to advertisings, reconstruction of advertising re-orientation links, annotation of node characteristics, extraction of 3-node short-path sections and detection rule generation based on machine learning. The malicious webpage advertising detection method does not need any modification to websites of publishers, is easy to implement, higher in applicability and does not depend on the contents of advertising webpages, so that the method has robustness to code obfuscation and shell adding. Compared with a single malicious webpage advertising detection technology, various types of malicious webpage advertising attacks such as phishing and click fraud can be detected by adopting the method, and the method has universality. For detection on malicious webpage advertisings utilizing advertising alliance, the method still has effectiveness.
