Abstract

Embodiments of the present invention provide a method and device for tracing virus sources. The method includes: monitoring and intercepting the data packets on each network card of the host; parsing out the SMB protocol packet from the intercepted data packet, and parsing out the operation information of each stage of the SMB session from the SMB protocol packet; Operation information to obtain complete file operation information and source information; save the file operation information and source information to the database; when the real-time protection system detects a shared directory virus file, obtain the source of the shared directory virus file by querying the database . The embodiment of the present invention obtains complete file operation information and source information by analyzing the SMB protocol packet, and writes it into the database. When a virus file propagated in the shared directory is detected, the source of the virus is obtained by querying the database, so that the administrator can accurately locate the network The source of the virus in the network is convenient to clean up the virus and prevent the repeated infection of the LAN virus.

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...
