/ DANGDI / DANGDI / DANGDI /A hacker accessed over eight million CPR numbers from Denmark's central register. This breach highlights digital security risks for everyone living in Denmark. CPR numbers are essential for daily life in Denmark. Residents use them for home loans, pharmacy prescriptions, and supermarket loyalty programs.
The hacker accessed the system using a former employee's login details. The employee used the password "123456" at a small Danish company. In an interview with Politiken, the hacker claimed he was shocked by the weak security. He stated he has no plans to leak or sell the stolen data. Digitalisation minister Christina Egelund admitted that system security was not good enough.
Editor Becky Waterton noted that Denmark's high-trust culture creates hidden security risks. People routinely trust others in daily local life. However, trust-based systems often fail to prepare for malicious attacks. Waterton advised residents to adopt practical precautions while maintaining everyday trust.
The source also reported other important national updates across Denmark. The government resumed processing 2,055 paused citizenship cases despite opposition criticism. A new EU rule imposed a tariff on small foreign parcels. Parcels worth 150 euros or less now face a minimum tariff of three euros. This tariff led to a sharp drop in foreign parcel imports. Finance minister Peter Hummelgaard unveiled a budget eliminating middle and top-top tax tiers.
