Abstract

The invention provides a method and a client device for detecting phishing websites and aims at solving the problem that existing detecting methods cannot detect newly-emerging phishing websites due to the delay. The method for detecting the phishing websites comprises obtaining the URL (uniform resource locator) of a target website and obtaining the page information of the target website according to the URL; extracting key area characteristics from the page information of the target website and subjecting the key area characteristics to the interface image similarity matching with key area characteristics in a real key area characteristic library; and if the matching degree of the interface image similarity matches with a second preset condition, determining the target website to be a phishing website, if not, determining the target website to be a normal website. The method for detecting the phishing websites completely utilizes local characteristics as the detection marks without image cutting or distance matching, thereby being applicable to the blurring mapping of images and effectively identifying the phishing websites even though the images of the phishing websites are deformed or warped.

Description

technical field [0001] The present application relates to network security technology, in particular to a method for detecting phishing websites and a client device. Background technique [0002] Phishing website is a kind of network fraud, which means criminals use various methods to counterfeit the URL address and page content of the real website, or use the loopholes in the real website server program to insert dangerous HTML codes into some webpages of the site, so as to Malicious websites that defraud users of private or sensitive information such as bank or credit card account numbers and passwords. [0003] Phishing websites are highly disseminated and do great harm to users. Therefore, the prior art proposes various methods for detecting phishing websites. Among them, the commonly used detection method is: set a blacklist, when the client browser accesses the server, first check whether the website to be accessed by the client browser is in the blacklist, and if so,...
