Abstract:

In recent years, both the number of phishing attacks and the losses caused by them have been increasing, and phishing attacks have become one of the main network security threats that people face. Currently, many phishing detection methods have been proposed to defend against phishing attacks, but most of the known phishing detection methods are passive detection and are prone to cause a large number of false positives. In response to the above issues, this paper proposed a phishing expansion method. Firstly, according to the phishing website information, it was analyzed in a multi-dimensional manner, and other related websites were obtained, so as to find more phishing websites that have not been discovered yet. Then, aiming at the visual counterfeiting characteristics of phishing websites, this paper proposed a phishing detection method based on deep learning, cutting the screenshots to obtain the area judged as a logo, and using EfficientNetV2 to mine visual counterfeiting characteristic. Finally, conducted a comprehensive evaluation of suspected phishing websites to reduce the false positive rate. The effectiveness of the method proposed in this paper was proved by the experimental verification of the existing phishing websites.

Key words: phishing detection, deep learning, picture cutting, expansion of phishing sites
