An apparatus for generating a signature that reflects the similarity of a malware detection and classification system of the present invention includes a pre-processing unit configured to generate an input vector from input information, a classification unit configured to calculate a latent vector which indicates the similarity between at least one malware classification and the input vector by performing a plurality of computations to which learned weights of a plurality of layers are applied on the input vector through a deep neural network model, and a signature generation unit configured to generate a signature of the malware in a form of a binary vector by quantizing the latent vector.

Apparatus for generating a signature that reflects the similarity of a malware detection and classification system based on deep neural networks, method therefor, and computer-readable recording medium recorded with a program for performing the method

Provides an apparatus for detecting variants of malicious code based on neural network learning, a method therefor and a computer readable recording medium storing a program for performing the method. According to the present invention, one-dimensional binary data is converted into two-dimensional data without separate extraction of features, and deep learning is performed through a neural network having a nonlinear multilayered structure, such that the features of the malicious code and variants thereof may be extracted by performing the deep learning. Therefore, since no separate feature extraction or artificial effort by an expert is required, an analysis time is reduced, and variants of malicious code that cannot be captured by existing malicious code classification tools may be detected by performing the deep learning.
