Martial law is always accompanied by an increased level of tension and threats to national security.

In this article, the author analyzed the legal provisions that were adopted as a supplement to the Criminal Code of Ukraine after the start of the full-scale invasion. The author notes that most of the articles in one way or another relate to criminal punishment for acts that occur in the information sphere and are related to the disclosure and dissemination of information, disinformation, unauthorized data transfer, etc. Based on this, the author emphasizes the need to criminalize acts during martial law relating to the digital, information and cyberspace spheres. The criminalization of certain categories of violations during the war is a topical issue, as it is aimed at ensuring the security of the state and preserving its integrity. The legislation should be comprehensively aimed at countering the aggressor and protecting civilians.
