Prosecutors confirm Miljodata cyberattack; no foreign state involvement suspected in breach affecting 15% of population.

Swedish prosecutors have confirmed that a cyberattack on IT systems provider Miljodata exposed the personal data of 1.5 million people, nearly 15% of Sweden’s population. The attack occurred during the weekend of August 23–24.

Authorities said the stolen data has been leaked online and includes names, addresses, and contact details. Prosecutor Sandra Helgadottir said the group Datacarry has claimed responsibility, though no foreign state involvement is suspected.

Media in Sweden reported that the hackers demanded 1.5 bitcoin (around $170,000) to prevent the release of the data. Miljodata confirmed the information has now been published on the darknet.

The Swedish Authority for Privacy Protection has received over 250 breach notifications, with 164 municipalities and four regional authorities impacted. Employees in Gothenburg were among those affected, according to SVT.

Private companies, including Volvo, SAS, and GKN Aerospace, also reported compromised data. Investigators are working to identify the perpetrators as the breach’s scale continues to raise concerns nationwide.
