Denmark Data Breach Exposes 8.8M People's Personal Data

Det Centrale Personregister (CPR) in Denmark has reported a serious security incident. By exploiting a Danish company's legal access to query information in the CPR system, the unauthorized individual gained access to names, addresses, CPR numbers, and other details of approximately 8.8 million registered citizens within the CPR system.

The conducted investigation reveals that the unauthorized access did not include names and addresses of individuals who had chosen to opt-out of name and address protection. The CPR administration has halted the company's access and is collaborating with experts and authorities to assess the incident's progression. The CPR administration has notified Datatilsynet, and the matter is under investigation by the police in cooperation with relevant authorities.

Further information on this security incident can be found on the Ministry of Research, Education, and Digitalization's website: https://ufm.dk/aktuelt/pressemeddelelser/2026/oktober/omfattende-uautoriseret-adgang-til-borgeres-cpr-oplysninger/.
