Embodiment Construction

[0030] The present invention provides a method and a system embodiment for detecting infectious viruses based on file headers, in order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purpose and characteristics of the present invention And advantage can be more obvious and easy to understand, below in conjunction with accompanying drawing technical scheme in the present invention is described in further detail:

[0031] The present invention firstly provides a method embodiment 1 of detecting an infectious virus based on a file header, such as figure 1 shown, including:

[0032] S101 monitors whether there is an open operation for the executable file, and if it exists, extracts the file header information of the executable file; wherein, the file header information during the open operation can be saved in the structure P1;

[0033] S102 monitors whether there is a sa...

Abstract

The invention discloses a method and system for detecting an infection type virus based on a file header. The method comprises: whether an opening operation for an executable file exists is monitored and if so, file header information of the executable file is extracted; whether a storage operation for the executable file exists is monitored and if so, file header information of the executable file is extracted; the file header information extracted twice is compared and whether any difference exists is determined; if so, the file head of the executable file is determined to be tampered and a counting operation of plus one is carried out; and when the number of tampered executable files exceeds a preset threshold value, infection type virus existence is determined, wherein the file header information includes an inlet point of the file header and the number, sizes, and attributes of nodes. Therefore, monitoring can be carried out from the perspective of a function behavior and thus whether an infection type virus exists in a system can be determined accurately.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and system for detecting infectious viruses based on file headers. Background technique [0002] Traditional malicious code detection methods include: first, identify malicious code based on signature matching; second, some anti-virus engines use behavior detection methods to identify malicious code; determination. However, infectious viruses often evade detection by means of encryption or deformation, which makes it difficult to extract signature features. In terms of behavior detection, it only extracts the behavior of malicious code, and does not perform special processing for specific file formats, and the processing is not meticulous. Therefore, the current detection of infectious viruses still stays in the method of detecting conventional malicious codes, and no special treatment is carried out according to its particularity. [0003] Infectious virus i...
