1. A generation device comprising:
generation circuitry configured to:
acquire information on software;
extract a feature quantity of the software from the information of the software acquired;
generate a cluster for the software based on the feature quantity extracted, and calculate a clustering result including a center of gravity of the cluster;
match the clustering result calculated with a past clustering result when a distance between a center of gravity of a cluster included in the past clustering result calculated from information on malware is equal to or less than a predetermined value; and
generate a graph representing a relationship between the software and the malware based on a result of matching, and
output the generated graph to a display,
wherein the generation circuitry is further configured to:
acquire information on a plurality of pieces of software in a time series order;
extract an operation or structural characteristic of the software as the feature quantity;
further update the past clustering result;
and connect a node corresponding to the clustering result matched and the node corresponding to the past clustering result by edges in a time series order.
