Abstract

The invention discloses a detection method for network phishing attacks. The detection method for the network phishing attacks includes: identifying a web access request initiated by a client; analyzing and recording a user request domain name corresponding to the web access request; searching a corresponding reply domain name in a preset website recognition bank according to page characteristics of a reply webpage returned by a web server; and comparing whether the user request domain name is identical with the reply domain name, if so, judging that the reply webpage has no network phishing attacks, and if not, judging that the reply webpage has the network phishing attacks. The invention further discloses a corresponding device. According to the detection method and the device for the network phishing attacks, the network phishing attacks can be identified and detected timely so that the effect of preventing the network phishing attacks can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for detecting phishing attacks. Background technique [0002] Phishing attackers usually use fraudulent emails and fake Web sites to carry out network fraud activities, and victims often disclose their private information, such as credit card numbers, bank card accounts, ID numbers, etc. Traditional anti-phishing is achieved by collecting malicious URL databases. However, this method cannot identify emerging phishing websites in a timely manner, and due to the incompleteness of malicious URL databases, it will also lead to some existing Phishing websites are also undetectable, thus limiting the effectiveness of anti-phishing attacks. Contents of the invention [0003] The main purpose of the present invention is to provide a detection method and device for phishing attacks, aiming at identifying and detecting phishing attacks in time, thereby improving...
