The present disclosure provides a system and method for allocating computer resources for detection of malicious files. In one aspect, the system comprises: a hardware processor configured to: form at least one behavior pattern grouping selected commands with shared parameters, apply a hash function on the at least one of the formed behavior pattern to obtain computed parameters, calculate a degree of harmfulness based on the obtained computed parameters using the hash function and a model for detection of malicious files, wherein the degree of harmfulness is a number value characterizing a probability that a malicious activity will be manifested by a time of computing said degree of harmfulness and wherein the model is a machine learning model trained using computed parameters of previous behavior patterns on which the hash function was applied to output degrees of harmfulness, and allocate the computing resources based on the calculated degree of harmfulness.

System and method of allocating computer resources for detection of malicious files

A method for detection of malicious files includes training a mapping model for mapping files in a probability space. A plurality of characteristics of an analyzed file is determined based on a set of rules. A mapping of the analyzed file in probability space is generated based on the determined plurality of characteristics. A first database is searched using the generated mapping of the analyzed file to determine whether the analyzed file is associated with a family of malicious files. The first database stores mappings associated with one or more families of malicious files. In response to determining that the analyzed file is associated with the family of malicious files, a selection of one or more methods of malware detection is made from a second database. The second database stores a plurality of malware detection methods. The selected method is used to detect the associated family.
