Problems solved by technology

However, if the writer of the backdoor script file code transforms the malicious code, he can hide the unique characteristics of the malicious code, thereby avoiding the detection of regular rules
Therefore, the backdoor script file cannot be detected accurately, which increases the misjudgment rate of backdoor script file detection

Abstract

The present application discloses a file detection method and device. The method includes: obtaining the file to be detected; performing normalization processing on the initial source code of the file to be detected to generate a normalized text; detecting whether the normalized text exists A code with a predetermined feature; if there is a code with a predetermined feature, it is determined that the file to be detected is a backdoor script file. This embodiment improves the accuracy of backdoor script file detection and reduces the misjudgment rate of backdoor script file detection.

Description

technical field [0001] The present application relates to the technical field of computer software, in particular to a file detection method and device. Background technique [0002] With the continuous development of network technology, people pay more and more attention to the issue of network security. At present, hackers can use various means to attack the network, and a common method of attacking a website is to use a backdoor script file to attack a website server. For example, some hackers often use Webshell (malicious WEB backdoor script) to attack website servers. Webshell is a script attack tool for web intrusion. After a hacker invades a website, the webshell file will be placed in the web directory of the website server and mixed with normal webpage files. Hackers can use the web to control the website server through webshell files, including uploading and downloading files, viewing databases, and executing arbitrary program commands. [0003] In the prior art...
