Denmark under attack: Hackers stole millions of records from government database

Denmark is facing an unprecedented data breach: hackers stole the personal details of approximately 8 million citizens and residents from the government's CPR database, including names, addresses, and social security numbers. Denmark's minister called the incident the most severe in the country's history. The breach was discovered today (Monday) but occurred in September.

Denmark is grappling with one of the most severe data breaches in its history. Hackers stole the personal details of approximately 8 million citizens and residents from the government's CPR (Central Person Register) database, a repository containing about 11 million records, some dating back decades. The stolen information includes full names, addresses, and Danish social security numbers. The breach was discovered today (Monday, October 5, 2026) but occurred in September. Denmark's minister, Christina Egelund, described the incident as extremely serious and expressed deep concern over its implications. The Danish government refused to reveal who was behind the attack. The incident joins a series of similar cyberattacks that have compromised national identity databases worldwide, including a breach in Turkey in 2016 and repeated exposures from India's Aadhaar database.
