Abstract

A system and method is provided for determining whether an electronic file is malicious. An exemplary method includes extracting resources from an electronic file; forming a first rule that establishes a functional dependency between the extracted resources; identifying, in a database of malicious file resources, a second rule associated with one or more of the extracted resources; comparing the formed first rule with the identified second rule to calculate a degree of similarity between first and second rules; and determining the electronic file to be a malicious file when the calculated degree of similarity exceeds a predetermined threshold value.
