Abstract: An activity trace extraction device executes malware to collect an analysis log including a plurality of activity traces of the malware, and executes the malware again in an environment indicating time information different from time information at the time of executing the malware to collect a time change analysis log including a plurality of activity traces of the malware. The activity trace extraction device updates the analysis log by removing, from the analysis log, the activity trace different from the activity trace of the time change analysis log among the plurality of activity traces included in the analysis log based on the analysis log and the time change analysis log. The activity trace extraction device generates trace information of the malware independent of time lapse based on the updated analysis log.

Abstract: An activity trace extraction device executes malware to collect an analysis log including a plurality of activity traces of the malware, and executes the malware again to collect an environment change analysis log including the plurality of activity traces of the malware assumed in a case where an execution environment of a system and a device used at execution of the malware and information unique to application software are changed. The activity trace extraction device updates, based on the analysis log and the environment change analysis log, the analysis log by removing, from the analysis log, an activity trace different from an activity trace of the environment change analysis log among the plurality of activity traces included in the analysis log. The activity trace extraction device generates trace information of the malware independent of the execution environment based on the analysis log updated.
