This paper investigates hybrid warfare by analysing its dimensions, that is, hybrid influencing, information warfare, kinetic warfare and cyber warfare, in a society’s information environment. The Grounded Theory approach was used to collect and analyse the data. Evidence of four thematic categories emerged, and each category was broken down into multiple items, derived from data and validated by past studies. The number of discovered item observations was 119, that is, 1–20 multiple item categories per thematic category, forming a total of 44 item categories. In this study, four thematic categories, their item categories and relationships between thematic categories defined the concept of hybrid warfare. Propositions regarding the thematic categories were then made on the basis of the inter-relationships between them. Seven higher-level abstractions of statements were found in the conceptual framework. Finally, six conclusions emerged from this study. First, modifying a society’s IE for a foreign state’s purposes is a coordinated political goal. Second, external pressure from foreign states is constant and seeks new forms of influencing. Third, a strategic goal exists to weaken society’s IE through frequent cyber operations, cyber attacks, fake information, social influence, political influence and psychological influence in order to prevent the progress of the society. Fourth, the goal of military manoeuvres and constant exercises with new military weapons near borders is to threaten the society. Fifth, foreign actors use different types of warfare to prevent the society’s decision-making. Sixth, hybrid influencing, information warfare, kinetic warfare and cyber warfare all overlap with each other in the society’s IE.
