Abstract

The invention discloses a malicious file repairing method. The method comprises the following steps: extracting file characteristics of the malicious file, wherein the file features comprise file attributes and family public feature strings, the file attributes comprise any one or a combination of any more of file size, node number and node authority, and the family public feature strings comprise any one or a combination of any more of file offset addresses, entry point offset addresses and node offset addresses; determining a target infectious virus family corresponding to the malicious file according to the file characteristics; and executing a file repair operation corresponding to the target infectious virus family on the malicious file. The method can accurately identify the virus family corresponding to the malicious file and improve the repair efficiency of the malicious file. The invention further discloses a malicious file repairing device, electronic equipment and a storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a method and device for repairing malicious files, an electronic device and a storage medium. Background technique [0002] With the development of artificial intelligence technology, using the generalization of AI (Artificial Intelligence) algorithm to identify malicious files has become one of the ways to detect malicious files. In related technologies, the malicious files detected by the AI ​​engine are directly sent to the infection-type repair module. The infection-type repair module will traverse the identification code of each family, and after identifying the specific family, it will go through the repair process of the specific family. The above-mentioned related technologies use a hard-coded method to traverse the identification codes of all virus families for file parsing and identification, and then determine the virus family to which the malici...
