The University of Nottingham confirmed on Wednesday that a hacking group gained access to its student records system in a breach affecting both current students and alums.

Nottingham University is a public research university with 7,000 staff and over 46,000 students, ranking in the Top 20 in the United Kingdom and the Top 100 worldwide.

The university told BleepingComputer in an emailed statement that the incident exposed a "significant amount of data," and that the breach has been reported to the UK's Information Commissioner's Office.

"The University of Nottingham has been the victim of a cyber incident and a significant amount of data in our student record system has been accessed by a well-known cybercriminal group", the university said. "We are working with the third party that maintains the platform to lead a forensic investigation."

"We take the privacy and security of data that we hold seriously, and we have reported this incident to Action Fraud and the Information Commissioner's Office," it added.
