Problems solved by technology
[0005] The malicious URL signature database only saves the existing malicious URLs, so the update of the malicious URL signature database is slow, the response to new malicious URLs is slow, and it cannot be identified in time. Moreover, the exact matching mode is used for identification, which is prone to missed killing problems

The invention discloses a malicious uniform resource locator (URL) recognition method and device and belongs to the fields of computer network security and communication. The malicious URL recognition method comprises the steps that a first URL to be recognized is acquired, if the first URL is not included in a preset first URL set, a first character preset in the first URL is acquired, the first character in the first URL is replaced with a second character in a preset similar relation with the first character, a second URL is obtained, and if the second URL is included in the preset first URL set, the first URL is recognized as a malicious URL. Through the malicious URL recognition method and device, the problem that a new malicious URL cannot be recognized in time is solved, and the problem that the malicious URL cannot be recognized in an off-line state is also solved; the effect of increasing the recognition rate of the malicious URL is achieved.
Description
technical field [0001] The present disclosure relates to the field of computer network security and communication technologies, and in particular to a method and device for identifying a malicious Uniform Resource Locator (Uniform Resource Locator, URL). Background technique [0002] With the development of the Internet, the Internet has brought a lot of convenience to people. However, while the Internet has brought many conveniences to people, its security issues have also greatly troubled network users. For example, some malicious URLs induce users to visit malicious websites such as fraudulent websites, websites linked to horses, and virus websites. Therefore, it is necessary to identify malicious URLs to improve the security of the Internet. [0003] At present, the following method is usually used to identify malicious URLs: collect existing malicious URLs to form a malicious URL feature library, when malicious URL identification is required, obtain the URL to be ident...
