ABSTRACT
The rapid expansion of digital technologies has transformed cyberspace into a critical domain of national security and international relations. States increasingly employ cyber capabilities for espionage, disruption, coercion, and military purposes, raising fundamental questions about the applicability of existing international law. This research paper examines whether the current legal framework governing cyber warfare is adequate to regulate hostile cyber operations. The study analyses the United Nations Charter, customary international law, the law of state responsibility, international humanitarian law, and the influential Tallinn Manual 2.0. Through an examination of major cyber incidents, including the 2007 Estonia attacks, the 2008 Georgia conflict, the Stuxnet operation against Iran, and cyber operations associated with the Russia–Ukraine conflict, the paper evaluates the strengths and limitations of the present framework. The research finds that while existing international law applies to cyber activities in principle, significant uncertainties remain regarding attribution, the threshold for the use of force, armed attack, due diligence obligations, and enforcement mechanisms. The paper concludes that the existing framework is partially adequate but insufficiently precise to address the complexities of contemporary cyber warfare. It recommends the development of clearer international norms, enhanced state cooperation, and greater institutional mechanisms for attribution and accountability.
Keywords: Cyber warfare, international law, UN Charter, state responsibility, Tallinn Manual, use of force, self-defence, international humanitarian law.
