Universidade Federal de Sergipe Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

For students, staff, alumni and partners of Universidade Federal de Sergipe, a ransomware group's claim that it has taken internal files raises immediate practical questions: whether personal or academic records are among the material, how those records might be misused, and what steps individuals can take while official details remain sparse. Public reporting so far does not confirm how many people are affected or exactly which records left the university's systems.

On 19 February 2025 the group known as thegentlemen listed the Federal University of Sergipe on its leak site, stating that internal files had been exfiltrated in a ransomware attack. The number of people involved is unknown, and the precise contents of the files have not been disclosed beyond the general description of internal material. That limited information is what is publicly available at present.

Breaking down the breach

According to the public listing dated 19 February 2025, thegentlemen claims to have conducted a ransomware attack against Universidade Federal de Sergipe and to have removed internal files. No further technical details—such as the initial access method, the duration of any intrusion, the volume of data taken, or confirmation that systems were encrypted—have been released in the available record. The number of individuals whose information may be involved remains unknown. The listing itself constitutes a claim by the group; independent verification of the full scope has not been provided in the reported facts.

Ransomware incidents of this type typically involve both encryption of systems and theft of data for leverage, yet the facts supplied here confirm only the group's assertion of exfiltration of internal files. Timing beyond the report date, the scale of any disruption to university operations, and any ransom demand are undisclosed.

The group behind it: thegentlemen

thegentlemen is a ransomware operation that has appeared in public reporting as a group that targets organisations, encrypts systems where possible, and posts victim names on a dedicated leak site to pressure payment. Like other actors in this category, it commonly claims to have stolen data before or during encryption and threatens to publish or sell that material if its demands are not met. Public documentation of the group describes double-extortion tactics—combining system disruption with the threat of data exposure—and the use of leak sites to advertise claimed victims.

In this instance the group has listed Universidade Federal de Sergipe and stated that internal files were exfiltrated. No additional statements from thegentlemen specific to this victim, such as sample files, exact file counts, or a publication deadline, appear in the provided facts. The listing should therefore be treated as an unverified claim until further confirmation emerges.

About Universidade Federal de Sergipe

Universidade Federal de Sergipe (UFS) is a Brazilian public higher-education institution based in the state of Sergipe. It maintains campuses in São Cristóvão, Aracaju, Itabaiana, Laranjeiras and Lagarto. Founded in 1967 through the consolidation of existing state colleges, it became the state's first public university and has grown into its most established and competitive public higher-education provider.

As a federal university, UFS holds large volumes of administrative, academic and personal records belonging to students, faculty, staff and research partners. A ransomware claim against such an institution is consequential because universities routinely process identity documents, contact details, academic histories, financial aid information and research data. Any confirmed exposure of those records can affect individuals long after the immediate incident and can disrupt teaching, research and administrative services.

What data was at risk

The available facts state only that internal files were exfiltrated in a ransomware attack. No inventory of specific data categories—such as student records, employee files, financial documents or research materials—has been published. Exact contents therefore remain unconfirmed.

Organisations of this type typically maintain databases containing names, national identification numbers, addresses, email accounts, academic transcripts, enrolment and employment records, and sometimes health or financial information related to scholarships or payroll. Whether any of those categories were among the files claimed by thegentlemen has not been verified in the public record. Until more precise disclosure occurs, it is not possible to state which data types were actually taken.

What's at stake

For individuals, the principal risks are identity misuse, targeted phishing that references genuine university details, and longer-term exposure of academic or employment history. Even when full data sets are not published, criminals can use partial records to craft convincing fraud attempts. For the university, stakes include potential operational interruption, costs of investigation and remediation, reputational damage, and regulatory obligations under Brazilian data-protection rules. Because the number of affected people is unknown and the precise files remain undisclosed, the concrete impact cannot yet be quantified; the risk is real but currently bounded by incomplete information.

Public institutions also face secondary effects: loss of trust among applicants and partners, possible delays in academic processes, and the need to notify authorities and affected parties once the scope is better understood. None of these outcomes is confirmed as having occurred; they represent the ordinary consequences that follow a ransomware claim of this nature.

If your data was in this claimed breach

If you are a current or former student, staff member or partner of Universidade Federal de Sergipe, treat the claim seriously while recognising that details are still limited. Monitor bank and credit accounts for unusual activity, enable multi-factor authentication on email and university-related accounts, and be sceptical of unsolicited messages that reference the university or request personal information. Change passwords on any accounts that reuse credentials associated with UFS systems. Keep records of any suspicious contact.

You can also run a free exposure scan of your email address to check whether that address has already appeared in known breach data sets. Such a scan does not confirm or rule out involvement in this specific incident, but it provides a practical starting point for understanding your wider exposure. Continue to watch for official statements from the university as more verified information becomes available.
