Abstract

An identifying device monitors malware to be analyzed and acquires, as log data, the malware, download data downloaded from a communication destination, and a relation of data transfer performed with the malware or the communication destination of the download data. Then, the identifying device creates, by using the acquired log data, a dependency relation graph that is a digraph in which the malware, download data, and communication destination are set as nodes and a dependency relation of each node is set as an edge. Then, the identifying device detects a malicious node by collating the respective nodes of the created dependency relation graph with the known maliciousness information, and traces an edge in a direction from a terminal point to a start point while setting the malicious node as a base point, and then identifies the traced node as a new malicious node.
