Abstract
Disclosed herein are methods and systems for detecting a source of malicious activity in a computer system. An exemplary method comprises gathering information related to the objects of the computer system, forming a graph based on the information gathered on the objects, selecting at least two induced subgraphs (hereinafter, subgraph) from the resulting graph, determining the coefficient of harmfulness for each selected subgraph, the coefficient of harmfulness representing a numerical characteristic describing the strength of the relations between the vertices of that subgraph, determining, from the selected subgraphs, a subgraph whose coefficient of harmfulness is a minimum among the determined coefficients of harmfulness of the subgraphs, and the total coefficient of harmfulness of the subgraphs related to that subgraph is a maximum, identifying the object correlated with at least one vertex of the determined subgraph as a source of the malicious activity in the computer system.
