In recent years, the application of artificial intelligence and big data analysis has become increasingly common, including in areas related to security and cybersecurity. The use of artificial intelligence and advanced big data analysis tools has enabled new critical perspectives on many different areas of the world around us. The purpose of this volume is to present the perspectives of researchers, experts and scientists, who are concerned with the problem of the distortion of reality by the authors of false narratives. The book focuses primarily on security matters, issues demanded by the international political and economic situation. Disinformation is a tool of hybrid war, shaping the social and economic environment long before the start of the Russian invasion of Ukraine. Since February 2022, the issues of post-truth, fake news, and disinformation have taken on additional gravity.
