Abstract: Disclosed herein a method and apparatus for detecting a malicious code based on an assembly language model. According to an embodiment of the present disclosure, there is provided a method for detecting a malicious code. The method comprising: generating an instruction code sequence by converting an input file, for which a malicious code is to be detected, into an assembly code; embedding the instruction code sequence by using a prelearned assembly language model for instruction code embedding and outputting an embedding result of the instruction code sequence; and detecting whether or not the input file is a malicious code, by using a prelearned malicious code classification model with the embedding result as an input.
