Sweden's national grid operator Svenska Kraftnät suffered a serious cyberattack over the weekend. A hacker group has claimed responsibility for the security breach.
The criminals published a countdown on darknet forums. They threaten to release stolen data this weekend unless their demands are met. The breach involves approximately 280 gigabytes of sensitive information.
Svenska Kraftnät has been working to determine what data was compromised. Officials now state they believe no personal information has leaked. They have examined parts of the server that was targeted in the attack.
Police have launched a major investigation into the incident. The case is classified as aggravated data breach with extortion elements. The National Operational Unit handles complex cyber crimes.
Authorities are verifying whether the group claiming responsibility actually conducted the attack. Police note that hackers often pretend to be other organizations.
This attack targets critical national infrastructure. The incident is being treated with extreme seriousness, according to law enforcement.
No suspects have been identified in the case yet. Both the Security Service and the National Cybersecurity Center are involved in the response.
Svenska Kraftnät operates Sweden's main power grid. The agency also manages electricity systems during crises, war, or major disruptions.
The grid operator confirms the cyberattack has not affected Sweden's electricity supply. Power distribution continues normally despite the security breach.
This incident highlights the growing vulnerability of essential services to digital threats. Critical infrastructure remains a prime target for cyber criminals seeking maximum impact.
