The embodiment of the invention provides a method and device for processing a baleful website library. The method comprises the following steps: acquiring a baleful uniform resource locator; taking a second-level domain or a third-level domain of the baleful uniform resource locator as a first uniform resource locator segment; calculating the hash value of the first uniform resource locator segment; acquiring at least one second uniform resource locator segment according to the baleful uniform resource locator; respectively calculating the hash value of the at least one second uniform resource locator segment; and storing the hash value of the first uniform resource locator segment and the hash value of the at least one second uniform resource locator segment to the baleful website library. By adopting the technical scheme of the invention, the coverage range of the hash values stored in the baleful website library is wide, so that the probability that the baleful uniform resource locator is detected in the baleful website library can effectively be increased when the paths or parameters of the baleful uniform resource locator are changed, and the efficiency of detection on the baleful uniform resource locator can be improved.
Description
technical field [0001] The embodiments of the present invention relate to the field of network technology, and in particular, to a method and device for processing a malicious URL library. Background technique [0002] With the rapid development of the Internet, the Internet is becoming more and more important to people's lives, but various malicious websites emerge in an endless stream, such as webpage Trojans, phishing websites and so on. Malicious websites directly threaten the safety of users, so it is imperative to strengthen the monitoring of malicious websites. [0003] In the prior art, the monitoring method of malicious Uniform Resource Locator (Uniform Resource Locator; URL) is mainly to detect based on the malicious URL library formed by the hash value of the existing malicious URL. Detect malicious URLs by using the malicious URL library of malicious URLs on the client, browser, security device, and mobile phone terminal of a personal computer (Person Computer; ...
