The University of Minnesota has confirmed that a threat actor has exfiltrated data from its systems, but says no malware infection was identified.
The confirmation comes one month after a threat actor boasted about accessing the university’s database containing information about students, staff, and faculty.
The attacker claimed to have accessed 7 million unique Social Security numbers, as the database contained records the university has been digitizing since 1989.
Responding to a SecurityWeek inquiry, the University of Minnesota confirmed that it initially learned about the hacker’s claims on July 21 and that it immediately launched an investigation to verify the validity of the attacker’s claims.
“The preliminary assessment is that the data at issue is from 2021 and earlier,” the educational institution told SecurityWeek.
The university also said that scans it has performed revealed no ongoing activity related to the incident and there were no system disruptions.
“Our investigation is continuing, but our security professionals have not detected any system malware (including ‘ransomware’), encrypted files or fraudulent emails related to the incident. There have been no known disruptions to current University operations as a result of this data security incident,” the university said.
The educational institution did not say what type of personal information was accessed in the data breach, and did not confirm the number of impacted individuals, but told SecurityWeek that it would inform all affected parties if it determines that sensitive information might have been compromised.
“To the extent any sensitive personal data was accessed, the University will notify affected individuals and provide resources to help protect against misuse of their information, as required by federal and state law, University policies, and in accordance with our obligations to the University community. The University has also notified state and federal regulatory agencies, as required by law,” the university said.
The University of Minnesota shared no details on how the data breach occurred.
