According to the Government of Norway Digital Agency, several public digital services have continued to face large-scale cyberattacks since Monday. The attack, which had lasted for three days, was the largest attack on the Agency ' s system to date, according to the Agency ' s spokesperson.
The attacks were mainly manifested in denial of service attacks. A large number of unusual flows have been directed to government platforms in an attempt to block online services, including systems that allow people to access multiple public services with a single account number. Norway indicated that the services remained operational for most of the time.
The attack took place after the Uku promised.
Norwegian media have widely cited a statement by Telegram that the pro-Russian hacker organization Server Killers claimed responsibility for the attack. According to the organization, after Norway's security cooperation with Ukraine was updated on 23 August, a “network war” was launched against Norway.
The Prime Minister of Norway, Jonas Gal Streux, had previously announced during his visit to Kyiv that Norway would continue to provide Ukraine with NOK 85 billion, or approximately $9.2 billion, in the next annual budget. This will be the third year in a row of equal assistance. The parties also committed themselves to continuing their cooperation in modern areas of combat, such as drone technology.
At the time of the publication of the report, Norwegian authorities had not commented on the organization ' s accounts.
The European alert network is escalating.
Since the full escalation of the Russian-Uu conflict in 2022, multinational countries in Europe have continued to raise their alerts to sabotage and malicious cyberoperation. European officials generally believe that such actions are intended to weaken external support for Ukraine while creating social panic and fragmentation and draining the resources of States for investigations.
Norway had previously reported similar incidents. In 2025, the Norwegian authorities indicated that Russian hackers were likely to be associated with the suspected destruction of a dam in the country. Hackers then entered the digital system of the remote control valve, opening one of the valves to increase the flow of water. According to the police, there was also a three-minute video on Telegram following the incident, which showed the dam control panel with a pro-Russian marking of cybercrime organizations.
The Nordic countries have faced successive attacks in recent years.
The Danish authorities also blamed Russia last year for cyber attacks on infrastructure and websites in Russia in 2024 and 2025. According to Danish officials, a pro-Russian organization, Z-Pentest, had launched a “destructive attack” on a water company in 2024, while another organization, NoName057(16), had been accused of attacking Danish websites prior to the local elections in 2025.
According to Norwegian media reports, Server Killers had previously been directly or indirectly associated with several cyberattacks in Norway and other European countries. The incident showed that the cyber confrontations around the U.N.U. are continuing to extend to the European public service.
