Abstract

The invention provides a software homology analysis method and a software homology analysis device based on software genes, which relate to the technical field of network security. The method comprises the following steps: Executing fragmentation operation on the code of the software to be analyzed to obtain the software genome of the software to be analyzed; Performing normalization operation oneach software gene in the software genome to obtain a target software genome; determining The preset software to which each software gene belongs in the target software genome based on the software gene library, and determine the software family to which the software to be analyzed belongs, wherein the software gene database comprises software genes of each preset software and identification information of each software gene, adopting The identification information to characterize the preset software to which the software gene belongs and the software family to which the preset software to which the software gene belongs, which solves the technical problem that the existing software homology analysis method has low accuracy in determining the software family to which the software to be analyzed belongs.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a software gene-based software homology analysis method and device. Background technique [0002] With the development of Internet technology, in order to gain profits, hackers usually write malicious software, or implant viruses in normal software, to attack and steal data from other people's devices, especially when conducting advanced persistent threat attacks on other people's devices Sometimes, hackers usually use a special Trojan virus to attack the device. [0003] At the same time, in order to attack the malware, it is necessary to judge the source of the malware, and then formulate a targeted protection plan by determining the family or organization to which the malware belongs. [0004] However, the existing methods are difficult to judge the source of the malware from the code level of the malware, and the accuracy of the judgment is low. [0005] For the ab...
