Code detection method and device, computer equipment and storage medium

Abstract

The invention relates to a code detection method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a to-be-detected target code; performing character string division on the target code to obtain a target sub-character string sequence; obtaining sub-character string vectors respectively corresponding to each target sub-character string in the target sub-character string sequence to form a vector sequence; performing linear feature extraction on the vector sequence to obtain a first extraction feature, and performing nonlinear feature extraction on the vector sequence to obtain a second extraction feature; performing fusion processing on the first extraction feature and the second extraction feature to obtain a fusion feature; and performing code detection based on the fusion feature to obtain a code detection result corresponding to the target code. The cloud server can utilize a malicious code detection model based on artificial intelligence to realize the code detection method, and the purpose of reducing network attacks is realized. By adopting the method, the malicious code detection accuracy can be improved.

Description

technical field [0001] The present application relates to the technical field of network security, and in particular, to a code detection method, apparatus, computer equipment and storage medium. Background technique [0002] With the development of computer technology, various malicious codes emerge in an endless stream, which brings great challenges to the field of network security and seriously endangers the production and lifestyle of users. The detection of malicious codes has become a hot issue. Malicious code refers to code that brings danger, such as malicious code on web pages that can use web pages to damage websites. [0003] At present, there are many methods to detect malicious code, such as malicious code detection methods based on artificial intelligence or cloud technology. However, due to the wide variety of malicious code and complex functions, the current malicious code detection methods often fail to detect malicious code. This results in low accuracy in...
