However, there ha ve not been a sufficient amount of research to understand the entire processes of this kind of attacks, from state actors making decisions to adopt cyber attacks against other countries to their affiliated actors executing the attacks. My research defines the processes as “State-Sponsored Offensive Cyber Activities” and sets its purpose as presenting the whole, big pictures of the activities in a manner suitable for understanding. This paper presents and details a research method which dissects the activity into multiple “Profile Elements” based on state-level “Strategy,” cyber attacks' “Tactics,” the activities' “Intentions” and “Capabilities and Opportunities” which allow for the activities, and then visualize the activities as their Elements and relations thereof. To verify the research method, this paper also applies the method to state actors on the whole and a particularly characteristic state actor, trying to understand their respective big pictures.}, title = {国家主体によるオフェンシブなサイバー活動全体像の研究~その戦略・戦術および意図・能力・機会~}, year = {2026} }
