Abstract

The embodiment of the invention provides a method and a device for tracking a virus source. The method comprises the following steps: monitoring and intercepting data packets on each network card of ahost; analyzing an SMB protocol packet from the intercepted data packet, and analyzing operation information of each stage of the SMB session from the SMB protocol packet; connecting the operation information of each stage of the SMB session in series to obtain complete file operation information and source information; storing the file operation information and the source information in a database; and when the real-time protection system detects the shared directory virus file, obtaining the source of the shared directory virus file by inquiring a database. According to the embodiment of the invention, the complete file operation information and source information are obtained by analyzing the SMB protocol packet. The method has the advantages that when the virus files transmitted by the shared directory are detected, the source of the virus is obtained by inquiring the database, so that an administrator can accurately position the source of the virus in the network, the virus is convenient to clean, and the local area network virus is prevented from being repeatedly infected.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a method and device for tracing virus sources. Background technique [0002] With the rapid development of computer network technology, the acquisition, sharing and dissemination of information has become more convenient, but the risk of information leakage has also increased. Within the government and enterprises, important documents are circulated and shared among multiple people, increasing the possibility of data leakage. [0003] Although the current anti-virus software has real-time monitoring functions, the anti-virus software cannot tell the user the source of the virus, especially when the shared directory is infected, it cannot locate the source of virus transmission, which will cause repeated virus infections. Therefore, how to effectively trace the source of shared directory viruses is an urgent problem to be solved. Contents of the...
