Abstract (en)

[origin: WO2021018929A1] A computer-implemented method, a system and computer programs for identifying a malicious file are disclosed. The method comprises performing a static analysis of a potentially malicious file to obtain a set of features that provide an abstract view of the file; performing a static machine learning classification process using as inputs said set of features, to obtain a preliminary classification output; and performing a fuzzy inference procedure based on possibilistic logic using as input variables said set of features and said preliminary classification output, to generate an enhanced classification output that identifies the potentially malicious file as a malicious file or a benign file.
