MULTI-STAGE PHISHING WEBSITE DETECTION METHOD AND SYSTEM

摘要

The present invention discloses a multi-stage phishing website detection method and system, and combines means of both fast filtering and accurate filtering. Multiple stages of fast filtering are used to control the number of potential phishing websites to be in a relatively small range; furthermore, an accurate determination model is trained by analyzing statistical features of positive and negative samples in a small range. The method comprises the following steps: selecting a to-be-detected range of websites to perform fast filtering and excluding obvious non-phishing websites therefrom; and performing accurate determination on the remaining range of the websites after the fast filtering to determine whether said websites are phishing websites. The system comprises: a fast filtering module, configured to select a range of to-be-detected websites to perform fast filtering and exclude obvious non-phishing websites therefrom; and an accurate determination module, configured to perform accurate determination on the remaining range of the to-be-detected websites after the fast filtering.
