Abstract

The invention discloses a webshell detection method and device based on artificial intelligence. The method comprises the following steps: step A, acquiring sample data of a webshell backdoor file; B,performing feature extraction on a webshell backdoor file sample to generate feature vectors of supervised learning, the feature vectors of supervised learning including at least one of text features, byte code features and abnormal behavior features; C, respectively establishing a learning model of each feature vector according to the feature vectors of the supervised learning; and D, detectingthe network flow by using the learning model.

Description

technical field [0001] The present application relates to the fields of computer and artificial intelligence, in particular to an artificial intelligence-based webshell detection method and device. Background technique [0002] Webshell is often referred to as the intruder's authority to operate the website server to a certain extent through the website port, such as executing system commands, deleting web pages, modifying the homepage, file access, etc. The webshell attack is divided into two steps: 1. The attacker uses the vulnerability of the web server to implant a dynamic webshell script (also known as a backdoor or a Trojan horse) into it. These scripts are mixed with the normal webpage files in the WEB directory of the website server; 2. The attacker uses a browser to access the web and uploads it to the webshell script to obtain a command execution environment to achieve the purpose of controlling the website server. [0003] In related technologies, webshell detect...
