Cybersecurity has lately been a concern to international legal scholarship, especially when cyberoperations and cyber warfare are involved. It is well-established in international law that a cyber-attack is connected to the notions of ‘violence’ and ‘physical harm’ and refers to either the means of warfare or their effects in an operation causing violent effects. The violent effects also constitute an attack even if the means used to cause those effects are not violent. States have recognised that cyberoperations against critical infrastructure and critical information infrastructure supporting essential services to the public cause serious and devastating security, economic, social and humanitarian consequences – both in times of peace and conflicts. Thus, deploying the law of state responsibility is most appropriate to determine when and how States are responsible and must make full reparation for the injury caused by their wrongful act. This contribution to the panel Cybersecurity and the Politics of Repair: Infrastructures, Maintenance, and Materialities will discuss the peculiarities of repair in relation to damages done to cyber and physical infrastructures under international rules and norms, including restitution, compensation, satisfaction and guarantees of non-repetition.
