Abstract

The invention belongs to the technical field of detection, and discloses a malicious code detection method and device, computer equipment and a readable storage medium, the method comprises the following steps: extracting data features of to-be-detected data according to a position relationship among instructions in the to-be-detected data; the data features are input into a pre-trained malicious code detection model, a code detection result output by the malicious code detection model is obtained, and the malicious code detection model is constructed based on machine learning. In this way, the malicious code detection model is constructed based on machine learning, the data features are extracted according to the position relation of the instructions in the to-be-detected data, malicious code detection is conducted on the data based on the data features by adopting the trained malicious code detection model, the code detection result is obtained, finer data features can be extracted, and the detection accuracy is improved. And thus, the code detection accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of detection, in particular, to a malicious code detection method, device, computer equipment and readable storage medium. Background technique [0002] Malicious code (Shellcode) is a piece of code used to exploit software vulnerabilities and execute. After the extended instruction pointer (Eip) overflows, a piece of shellcode machine code that can be executed by the CPU is inserted to control the device to perform attacks. arbitrary instructions from the author. [0003] In the prior art, methods such as abnormal behavior detection and code matching are usually used to detect whether there is Shellcode. [0004] However, in this way, the accuracy rate of malicious code detection is low, and the false negative rate is high. Contents of the invention [0005] The purpose of the embodiments of the present application is to provide a malicious code detection method, device, computer equipment and...
