University of Valencia Hit by Nova Ransomware: Ransomware Claim — What’s Alleged & What To Do

On May 23, 2026, the Nova ransomware group listed the University of Valencia on its leak site, claiming to have stolen sensitive data from the institution. The claim, which appeared on ransomware tracking sites the same day, alleges the theft of student and staff information including personal photographs of children. The number of individuals affected remains unknown, and no independent confirmation of the data theft has been made public. This development reflects the continued focus of ransomware operators on higher-education targets, where large volumes of personal records are stored across interconnected systems.

What happened

The incident was first noted on May 23, 2026, when the Nova group posted a claim regarding the University of Valencia on its leak site. The group alleged theft of sensitive student and staff data, including personal children's photos stored on servers, and stated that it had offered samples of the material. The estimated date of the attack is the same day the listing appeared. No information has been released about the method of intrusion, the volume of data taken, or whether any systems were encrypted.

Inside nova

Nova operates as a ransomware group that maintains a public leak site to advertise claimed intrusions. These actors typically exfiltrate data during an intrusion and later publish portions of it to increase pressure on the target. The listing of the University of Valencia constitutes the group's claim; no separate verification of the asserted theft has been provided by the institution or by investigators.

About University of Valencia

The University of Valencia is a public research university in Spain that maintains records for students, faculty, and staff. Institutions of this type routinely hold enrollment information, academic records, employment details, and, in some cases, photographs or other personal files related to minors participating in university programs. A breach at such an organization can affect large numbers of individuals whose data is retained for administrative and research purposes.

What was likely exposed

The Nova group claimed exposure of personal photographs, student data, and other sensitive personal information. The exact contents of any exfiltrated material have not been independently confirmed, and the number of records involved remains undisclosed. Organizations in the higher-education sector commonly store names, contact details, academic histories, identification documents, and limited family-related records, but whether any of these categories were accessed in this case is unverified.

Why it matters

Personal data held by universities can be used for identity-related fraud or targeted social-engineering attempts. Photographs described as sensitive may carry additional privacy implications for the individuals depicted. For the institution, the incident adds to the operational burden of assessing scope, notifying affected parties where required, and reviewing access controls across its networks.

If your data was in this claimed breach

Individuals who believe their information may have been held by the University of Valencia should begin by reviewing account statements and credit reports for unusual activity. Changing passwords for any university-linked services and enabling multi-factor authentication where available are immediate steps that limit further exposure.
