Attackers entered a test environment; about 20,000 ID-card PIN codes were reset, and Monday's outage was the same incident.

The University of Copenhagen said attackers entered a test environment detected on 20 October and disclosed on 23 October, taking names, national identity numbers, phone numbers and personal emails for about 525,000 people. Systems including Workzone and Nimbus were shut on Monday; the university later said that activity belonged to the original breach, not a second attack. PIN codes for about 20,000 staff and student ID cards were replaced. UCPH notified the Danish Data Protection Agency.
