A pro-Russian hacker group on Wednesday claimed responsibility for a cyberattack that has affected multiple Norwegian government digital services over the past three days.
The cyberattack has been ongoing since Monday, said Are Kvistad, a spokesperson for the Norwegian Digitalization Agency (Digdir), the state body in charge of making Norway’s public services more digital and user-friendly, told The Associated Press.
“It’s the biggest attack against Digdir solutions that we have ever experienced,” Kvistad said.
The denial-of-service attacks meant that hackers pushed massive traffic toward the agency in order to block services, including one that enables citizens to use one login across multiple public services.
However, the Digdir spokesman said that the agency managed to keep the services running “practically all the time.”
In a Telegram post on Wednesday widely reported by Norwegian media, the pro-Russian hacker group Server Killers claimed responsibility for the attack and said it had declared cyber war on Norway after the country renewed its security cooperation with Ukraine on Aug. 23.
