specific Embodiment

[0070] A cross-platform Office nested file content parsing method is provided, which is executed through the parsing engine, and the method includes:

[0071] S1: The monitoring system Hook leaked office documents;

[0072] S2: The parsing engine loads the file to be parsed;

[0073] S3: The parsing engine parses the file type. If it is ODF OOXML type, go to S4-1; if it is ODFXML type, go to S4-2; if it is OLE type, go to S4-3; if it is XLSB type, go to S4-4; if it is RTF type, go to S4-5 ;

[0074] S4-1: Parse the ODF OOXML file directory;

[0075] S4-2: Parse the ODFXML file directory;

[0076] S4-3: Parse the OLE file directory;

[0077] S4-4: Parse the XLSB file directory;

[0078] S4-5: Parse the RTF file directory;

[0079] S5: Analyze the file attribute information according to the file directory;

[0080] S6: According to the file directory, parse the content of the file body;

[0081] S7: judge whether the current file contains a nested file, if it contains a...

Abstract

The invention provides a file analysis method and device, electronic equipment and a storage medium, and the method comprises the steps: (A) determining a target Office file which is an Office file operated on terminal equipment in real time; (B) determining a target file type of the to-be-analyzed Office file of the current layer; (C) obtaining a file directory of the Office file to be analyzed according to a file directory analysis logic corresponding to the target file type; (D) according to the file directory, outputting file attribute information and file content of the Office file to be analyzed; (E) according to the file directory, determining whether a nested file exists in the Office file to be analyzed; and (F) if the nested file exists in the to-be-analyzed Office file, obtaining the nested file, and taking the nested file as the to-be-analyzed Office file, so as to return to execute the step (B).

Description

technical field [0001] The present application relates to the technical field of file analysis, and in particular, to a file analysis method, device, electronic equipment, and storage medium. Background technique [0002] The mainstream Office nested file suite providers on the market include Microsoft Office, Kingsoft WPSOffice, Yongzhong Office, etc. There are also some open source software such as Open Office and Libre Office. The above file format types can be classified into three categories: OLE, ODF, and OOXML, and the file formats of different versions are also different. When existing platforms such as Microsoft Windows API interface, NET NPOI library or Java POI class library parse files, there are usually problems such as incomplete parsing of nested files, incompatible file formats, and poor parsing efficiency. Therefore, a cross-platform Office nested file content analysis method with strong compatibility and comprehensive analysis content is needed. Contents...
