Abstract: An emerging issue called cyberterrorism is a fatal problem causing a disturbance in the cyberspace. To unravel underlying issues about cyberterrorism, it is imperative to look into available documents found in the NATO's repository. Extraction of articles using web-mining technique and performed topic modelling on NLP. Moreover, this study employed latent Dirichlet allocation algorithm, an unsupervised machine learning to generate latent themes from the text corpus. An identified five underlying themes revealed based on the result. Finally, a profound understanding of cyberterrorism as a pragmatic menace of the cyberspace through a worldwide spread of black propaganda, recruitment, computer and network hacking, economic sabotage and others revealed. As a result, countries around the world, including NATO and its allies, had continuously improved its capabilities against cyberterrorism.
