The objective of the article was to identify new threats to the national security of countries and, at the same time, to determine the adaptation tasks related to their identification. The synergistic approach, comparative legal analysis methods and foresight were the main tools of this research. Manipulation actions involving deep forgeries are spreading rapidly. Autonomous weapons with artificial intelligence are used to create negative fake events. Criminal use of users’ smart devices to create a unique behavioural profile has been detected. New cyber threats to Ukraine’s national security during the military conflict are characterized by attempts to disrupt critical infrastructure. It is concluded that “cyber looting” has emerged with the use of social engineering methods. The activities of the Belgian Center for Cyber Security (CCB) are a positive example of the identification of new cyber threats in the countries of the European Union EU. Furthermore, CCB performs activities related to the identification, monitoring and analysis of online security issues. Coordination between relevant services and agencies, public authorities, private sector and academia is ensured.
