What Happened

The Danish government confirmed that hackers breached the country's Central Person Register (CPR), stealing personal data of around 8 million citizens and residents, including people living abroad and deceased individuals. The compromised information includes names, addresses and national identification numbers. Authorities said the breach occurred after attackers abused a private company's legitimate access to the database and was discovered on October 2.

Key Takeaways

Considered one of Denmark's largest-ever cyber incidents, the breach has triggered a police investigation and a comprehensive security review of the CPR system. The incident highlights growing cybersecurity risks around government-held identity databases and third-party access.
