Sweden Imposes $183K GDPR Fine on Miljödata After Ransomware Breach Affects 2.2M Citizens
In August 2025, Swedish IT systems provider Miljödata suffered a cyberattack that compromised sensitive data of 2.2 million people across over 200 municipalities. The attackers demanded 1.5 Bitcoin ransom but published the stolen data on the dark web under "Datacarry" when payment was not made. The breach exposed personal identity numbers, contact information, sickness absence records, rehabilitation data, and school incidents involving minors. Sweden's data privacy regulator IMY subsequently fined Miljödata $183,000 for GDPR violations, citing inadequate security measures including insufficient software validation and lack of automated real-time monitoring. This incident highlights the escalating regulatory enforcement of GDPR compliance following ransomware attacks, as European authorities increasingly impose substantial penalties for security negligence that enables data breaches affecting millions of citizens.
