Embodiment Construction

[0037] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0038] Such as figure 1 As shown, it is a schematic flowchart of a malicious link detection method provided by an embodiment of the present invention, the method includes:

[0039] S1. Obtain a link to be detected.

[0040] S2, extract key characters of links to be detected according to preset extraction rules.

[0041] S3, generate a hash value based on key characters.

[0042] S4, matching the malicious link from the preset malicious link database according to the hash value.

[0043] S5, when a malicious link with the same hash value is matched, prompting that the link to be detected is a malicious link.

[0044] Preferably, it also includes:

[0045] When no malicious link with the same hash value is matche...

Abstract

The invention discloses a malicious link detection method and system, and relates to the field of computer. The malicious link detection method comprises the steps of obtaining a to-be-detected link;extracting a key character of the to-be-detected link based on a preset extraction rule; generating a hash value based on the key character; matching a malicious link from a preset malicious link database based on the hash value; and when the malicious link with the same hash value is matched, indicating that the to-be-detected link is the malicious link. According to the malicious link detectionmethod and system provided by the invention, the malicious link can be detected rapidly by extracting the key character in the link, generating the hash value and matching the hash value directly withthe pre-stored hash value in the database; one-by one detection can be avoided during the link detection; and the malicious link detection method and system have the advantages of being high in detection efficiency and saving system resources.

Description

technical field [0001] The invention relates to the field of computers, in particular to a malicious link detection method and system. Background technique [0002] With the development of Internet technology, people will also encounter some problems when using the Internet. For example, when browsing the web, the entire screen is filled with web pages that appear continuously, or when browsing information on the Internet, clicking a web link , As a result, a virus or a lot of rogue software is installed. These links reduce the user's online experience and bring certain security risks to the user. [0003] At present, the existing link detection methods can only detect links one by one after suspicious links are found, which has the disadvantage of low detection efficiency and wastes system resources. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a malicious link detection method and system for the deficiencie...
