Problems solved by technology

[0003] At present, with regard to polymorphic infectious viruses, using static processing to identify any encryption algorithm requires a large workload, and the range of keys or encryption positions obtained through static processing is often limited. Large, unable to handle all encryption algorithms of polymorphic infection viruses
Therefore, the existing static processing methods cannot be effectively applied to the processing of polymorphic infectious viruses, and the processing methods of polymorphic infectious viruses are often complicated and require a large workload.

Abstract

The invention discloses a polymorphic virus analyzing method and device and a virus processing method and device. The polymorphic virus analyzing method includes infecting a target file through polymorphic virus and utilizing the acquired infected file as a polymorphic virus infected file; loading the polymorphic virus infected file through a command simulator; utilizing the command simulator to execute the polymorphic virus infected file and acquiring a command set generated by the command simulator during execution of the polymorphic virus infected file; comparing the preset command characteristic and concentrated commands to acquire the decryption position. The polymorphic virus analyzing method simplifies the polymorphic infectious virus processing method, reduces the workload of analysis of polymorphic infectious virus, and improves the analyzing efficiency.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a polymorphic virus analysis method and analysis device, and virus processing method and processing device. Background technique [0002] With the development of computer technology, there are more and more types of computer viruses. Polymorphic infection virus is a more complex file virus that can infect normal files into virus files. Since the polymorphic infectious virus utilizes the polymorphic engine, in the process of the polymorphic infectious virus infecting normal files, the form of the code that the polymorphic infectious virus infects the normal file is different each time. [0003] At present, with regard to polymorphic infectious viruses, using static processing to identify any encryption algorithm requires a large amount of work, and the range of keys or encryption locations obtained through static processing is often not available. Large, unable to handle all ...
