Problems solved by technology

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 sites are also undetectable, limiting the effectiveness of anti-phishing attacks

[0082] Based on the first embodiment of the detection device for phishing attacks of the present invention, the detection device for phishing attacks further includes:

[0083] The request processing module 50 is configured to perform corresponding processing on the web access request requested by the client.

[0084] After comparing whether the user request domain name and the response domain name are the same, and detecting whether there is a phishing attack in the response webpage according to the comparison result, the request processing module 50 further determines the web access requested by the client according to the different detection results Request the corresponding processing separately.

[0085] In this embodiment, the request processing module 50 is used to:

[0086] When it is determined that there is a phishing attack in the response webpage, the connection of the response webpage is blocked or redirected according to the user's configuration;

[0087] When it is deter...

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 present invention relates to the field of Internet technology, in particular to a method and device for detecting phishing attacks. Background technique [0002] Phishing attackers usually use deceptive e-mails and forged Web sites to carry out online fraud, and the victims often reveal their personal information, such as credit card numbers, bank card accounts, ID numbers, and so on. Traditional anti-phishing is achieved by collecting malicious URL libraries. However, this method cannot identify new phishing websites in a timely manner, and due to the incompleteness of malicious URL libraries, it will also cause some existing Phishing websites cannot be detected, which limits the effectiveness of anti-phishing attacks. Summary of the invention [0003] The main purpose of the present invention is to provide a method and device for detecting phishing attacks, aiming to identify and detect phishing attacks in time, thereby improving the effect of prevent...
