GoKawiilUniversity of Copenhagen breach exposes data of 525,000 people
The University of Copenhagen confirmed hackers breached one of its test environments, detecting the intrusion last Tuesday and disclosing it days later. Exposed data for roughly 525,000 people may include full names, national identity numbers, phone numbers and email addresses, while a later update added 20,000 staff and students whose campus access PIN codes were also compromised.
GoKawiil's interpretation of the reporting above, not reported fact.
The exposure of national ID numbers and contact details raises the risk of phishing and social engineering targeting students and staff, according to the university's own warning. The incident also triggers GDPR obligations, meaning Danish and EU regulators will likely scrutinize how the breach occurred and whether notification requirements were met.
- A test environment breach exposed personal data of about 525,000 people, including national ID numbers.
- An additional 20,000 staff and students had physical access PIN codes compromised, prompting temporary access restrictions.
- The university says core operational systems were unaffected and has reported the incident under GDPR.
