A major cyberattack has affected multiple Norwegian government digital services. The attack, which began on Monday, has been ongoing for three days. A pro-Russian hacker group has claimed responsibility for the attack.

The cyberattack involved denial-of-service attacks, where hackers pushed massive traffic toward the Norwegian Digitalization Agency to block services. One of the affected services allows citizens to use a single login across multiple public services.

Further details about the attack are available, including comments from a spokesperson for the Norwegian Digitalization Agency, who described it as the biggest attack against their solutions.
