Sweden's national power grid operator confirmed hackers copied nearly 290 gigabytes of data from an external server. The agency stated this information was not operationally critical. Sweden's electrical system remains unaffected by the breach.
Security officials discovered the intrusion over the weekend through independent experts. The hackers copied data from a server located outside the main network. This server wasn't connected to critical systems controlling Sweden's power infrastructure.
Cem Göcgören, the agency's information security chief, acknowledged they didn't detect the breach themselves. He said this incident serves as an important reminder to continuously work on IT security. Early indications suggest no sensitive information was compromised.
The security chief declined to comment on potential perpetrators or ransom demands. He referred such questions to police investigators. The compromised server has been shut down completely.
Analysts are now focusing on understanding what specific data was accessed. Officials confirmed the stolen information doesn't include personal data about individuals. The investigation continues to determine the full scope of the breach.
This incident highlights the constant cybersecurity challenges facing critical infrastructure operators. While this breach appears contained, it demonstrates how external systems remain vulnerable targets for hackers seeking to disrupt essential services.
