Abstract	The rapid growth of digital technology has changed cyberspace into a new battleground, raising serious legal and humanitarian issues for the international community. Cyber warfare has increasingly become a way to wage modern conflict. It can disrupt critical infrastructure, financial systems, healthcare services, military operations, and civilian communications without using traditional weapons. However, the changing nature of cyber-attacks brings up a key question: is existing International Humanitarian Law (IHL) adequate to regulate such actions during armed conflict? This paper examines whether current IHL principles, especially distinction, proportionality, military necessity, and state responsibility, can effectively address the complexities of cyber warfare. The study looks at relevant international legal documents, such as the Geneva Conventions, Tallinn Manual 2.0, and customary international law, along with recent cyber incidents involving state and non-state actors. It argues that while existing IHL principles offer a basic framework for regulating cyber operations, there are still significant legal uncertainties about attribution, civilian protection, the threshold for armed attack, and accountability mechanisms. The paper also explores the challenges that developing countries face when responding to cyber threats due to their technological and legal limitations. Finally, the study suggests creating clearer international norms and collaborative mechanisms to ensure effective humanitarian protection in cyberspace. The research aims to add to current discussions on updating international law to reflect the realities of digital conflict in the twenty-first century.
