The University of Copenhagen (UCPH) says a cyber incident exposed personal data tied to roughly 525,000 people. Multiple outlets report that hackers accessed a test environment containing that information, and that some PIN codes may have been taken, prompting the university to reset them.
In response to the activity, UCPH shuts down several administrative systems as a precaution. One report says the university later rules out a second cyberattack, describing the Monday shutdown of systems such as Workzone and Nimbus as preventive and linked to the breach disclosed the previous week. Another outlet summarizes the breach more generally as compromising data on “half a million” people.
Across the coverage, the core details—UCPH confirmation, the scale of affected individuals, and the use of a test environment—are consistent. Differences are mostly in how specific the reporting is (for example, mention of PIN codes) and in slight wording about the size of the impacted population.
