Abstract

The invention provides a method for detecting malicious codes based on a uniform resource locator. The method comprises the following steps of: monitoring a computer operating system and acquiring URL (uniform resource locator) of an access network of the system; acquiring Query domain information of the URL through analyzing the URL; carrying out pattern-matching for the Query domain information and the characteristic data pre-stored in the Query domain virus feature base; if the matching is successful, judging that the malicious codes exist, and carrying out corresponding treatment according to the preset operation; or else, continuing monitoring. The invention provides a system for detecting the malicious codes based on the uniform resource locator. The method and the system for detecting the malicious codes based on the uniform resource locator have a simple use manner, do not use huge virus characteristic data and have good detection rate for the malicious codes of stealing ID.

Description

technical field [0001] The invention relates to the technical field of computer network security, in particular to a URL (Uniform Resource Locator, uniform resource locator)-based Trojan horse detection method and system. Background technique [0002] With the widespread popularity of the Internet, people's activities on the Internet are increasing day by day, and protecting virtual property in the network world has become one of the main tasks of anti-virus software. At present, the main detection method of anti-virus software is signature matching. Virus manufacturers need to continuously upgrade virus signature databases to fight against the constantly updated Trojan horse programs of network hackers. At this stage, many hackers who do not know how to write programs can buy ready-made Trojan horse programs. Some large software protection organizations or individuals have launched a lot of encrypted protection shells to protect software intellectual property rights and oth...
