Denmark has experienced a significant data breach, in which unauthorized persons misused the legitimate access rights of a Danish private company to improperly search the Central Population Register. This led to the unauthorized exposure of names, addresses, and CPR numbers (personal identification numbers) of approximately 8.8 million registered individuals. At present, the system access rights of the company involved have been entirely revoked, and the police have initiated an investigation, although the perpetrators behind the incident remain unidentified. Denmark's Minister for Digitalization described the incident as extremely serious and has mandated a thorough security review of the CPR system. The CPR system serves as the backbone of Denmark's digital public administration framework, housing around 11 million historical records, encompassing data on deceased individuals and those who have relocated abroad. However, the data of individuals who have requested information confidentiality protection was not compromised in this breach. Management first detected irregularities on October 2, with unauthorized search activities confirmed to have taken place in September.
