Universitatea Politehnica din Bucuresti Listed by fog Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Educational institutions continue to face sustained pressure from ransomware operators who treat universities as high-value targets holding large volumes of personal, academic and research data. In this climate, the appearance of Universitatea Politehnica din Bucuresti on a ransomware leak site in early February 2025 fits a broader pattern of claims against higher-education organisations across Europe and beyond. Public detail remains limited, yet the listing itself raises concrete questions about potential exposure of internal material and the practical risks that follow for students, staff and partners.

What is known so far comes chiefly from the threat actor’s own announcement rather than independent confirmation. The incident matters because any successful ransomware intrusion at a major technical university can affect not only day-to-day operations but also the personal information of thousands of individuals and the integrity of research projects.

What happened

On 9 February 2025, Universitatea Politehnica din Bucuresti was listed by the fog ransomware group. The group claims that internal files were exfiltrated during a ransomware attack. No further technical details—such as the initial access vector, the precise date of intrusion, the volume of data taken, or whether systems were encrypted—have been publicly disclosed. The number of people potentially affected is unknown. A brief extract associated with the listing also names two other organisations, Maxvy Technologies Pvt and iRidge Inc., though no connection between the three entities has been explained. At present the only verified public fact is the leak-site claim itself; independent verification of the breach or of the data’s authenticity has not been reported.

The group behind it: fog

Fog is a ransomware operation that has been observed conducting double-extortion campaigns: encrypting systems while simultaneously stealing data and threatening to publish it if a ransom is not paid. Like many contemporary groups, it maintains a dedicated leak site where it posts victim names and, in some cases, samples of stolen material to increase pressure. Public reporting on fog indicates a preference for opportunistic targeting across multiple sectors rather than exclusive focus on any single industry. The group typically claims responsibility by listing organisations and asserting that data has been exfiltrated; such claims are not independently verified at the moment of posting. In the present case, fog’s listing of Universitatea Politehnica din Bucuresti should therefore be treated as an unverified assertion by the actor rather than confirmed fact.

Universitatea Politehnica din Bucuresti and its sector

Universitatea Politehnica din Bucuresti is Romania’s largest technical university, educating tens of thousands of students in engineering, computer science, electronics and related fields. As a public higher-education institution it maintains extensive records on current and former students, academic staff, administrative personnel, research collaborators and external partners. Universities of this type routinely hold personal identification data, academic transcripts, contact details, financial and scholarship information, research datasets and internal administrative documents. A ransomware incident at such an organisation is consequential because disruption can halt teaching and research activities, while any subsequent data exposure can affect individuals long after systems are restored. The education sector has repeatedly appeared on ransomware target lists precisely because of the combination of valuable data, complex IT environments and often constrained cybersecurity budgets.

What data was at risk

According to the fog listing, internal files were exfiltrated. No more granular inventory—such as specific categories of personal data, research files or administrative records—has been made public. Organisations of this kind typically store student and staff personal information, academic records, research materials, contracts and internal correspondence. Because the exact contents remain unconfirmed, it is not possible to state with certainty which of these categories, if any, were among the material claimed to have been taken. The absence of a detailed disclosure means affected individuals cannot yet determine the precise nature of any exposure.

Why it matters

For individuals whose information may have been involved, the practical risks include identity misuse, targeted phishing, and long-term exposure of academic or employment history. Even limited internal files can contain enough personal detail to enable social-engineering attacks or credential stuffing. For the university itself, a claimed breach would raise operational, legal and reputational considerations: potential regulatory notification duties under data-protection law, the cost of investigation and remediation, and the need to reassure students, staff and research partners. Because the scale and contents remain unknown, the full extent of these consequences cannot yet be assessed; the listing alone, however, is sufficient to warrant vigilance and preparatory steps by anyone connected to the institution.

Were you affected?

If you are a current or former student, staff member or partner of Universitatea Politehnica din Bucuresti, treat the claim seriously but without panic. Monitor financial and academic accounts for unusual activity, enable multi-factor authentication wherever available, and be alert to unsolicited messages that reference university matters. Change passwords on any accounts that may have reused credentials linked to university systems. You can also run a free exposure scan of your email address to check whether it has already appeared in known breach datasets; such a check provides an additional early-warning signal while official details remain limited. Continue to follow any guidance the university itself issues as more information becomes available.
