摘要: A computer system comprises an analysis module configured to execute dynamic analysis for a sample of a malicious program, and to output an analysis result including a coupling destination to and from which the malicious program communicates; a variation detection module configured to detect variation of the coupling destination based on results of cyclic observation of the coupling destination, and to output a result of the detection; and an information sharing module configured to store information output from the analysis module and information output from the variation detection module in a form that allows sharing among a plurality of external computers.
