A pro-Russian hacker group named Server Killers claimed responsibility for a major denial-of-service cyberattack targeting Norway's public digital services managed by the Norwegian Digitalization Agency (Digdir). The attack, ongoing since Monday August 24, 2026, pushed massive traffic to block services, including a unified login system for multiple public services. Despite the attack, services remained operational practically all the time. The attack was declared as cyber war in response to Norway renewing security cooperation with Ukraine on August 23, 2026. This follows Norwegian Prime Minister Jonas Gahr Støre's announcement of providing $9.2 billion USD aid to Ukraine in the 2027 budget. The incident follows previous pro-Russian cyber sabotage attempts in Norway and Denmark attributed to Russia and linked groups.
