Full Legal Summary
Detailed

In early 2021, a Norwegian municipality (Østre Toten kommune) realized they had been exposed to a serious ransomware attack that locked employees out of key IT systems. Data had been encrypted and backups deleted. About 30,000 documents were affected by the breach, including information about ethnic origin, political opinion, religious belief, trade union membership, sex life/sexual orientation, health, pedagogical diagnosis, birth number, electronic ID and bank account. About 2,000 documents were later discovered up for sale on the dark web. In total, about 160 GB of data was extracted and a large amount of data was irreparably lost.

The municipality notified the DPA about the breach and kept their inhabitants continuously informed. They also initiated a comprehensive work to establish routines for processing personal data and for data breach management.

For this, the Norwegian DPA fined the municipality €409,768 (NOK 4,000,000). In addition, the DPA instructed the municipality to establish and implement an appropriate information security management system, and to conduct (and document) risk assessments for all key systems in their infrastructure with the aim of i
