Malicious software classification method and device and storage medium

The embodiment of the invention discloses a malicious software classification method and device and a storage medium, and is applied to the technical field of malicious software classification. The method provided by the embodiment of the invention comprises the following steps: converting a binary file corresponding to the to-be-classified malicious software into pixel points to obtain a grayscale image corresponding to the to-be-classified malicious software; constructing a first grayscale image according to a pixel entropy value of a pixel region in the grayscale image; constructing a second grayscale image according to the relative size of pixels in a pixel region in the grayscale image; taking the first grayscale image, the second grayscale image and the grayscale image as three channels of a three-channel image in sequence, and synthesizing a target three-channel image corresponding to the to-be-classified malicious software; and inputting the target three-channel image into a pre-trained malicious clas
