Thammasat University Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Thammasat University was listed by thegentlemen ransomware group on 11 February 2026, with internal files reported to have been exfiltrated. Individuals connected to the university are advised to check whether their data was exposed and to take appropriate protective steps.
Breaking down the breach
The only confirmed information comes from the February 11, 2026 listing. It asserts that files were taken but provides no counts, file names, or proof of encryption. No independent confirmation of the data's exposure or the attack's technical details has been made public. The university has not issued a statement on the matter in the available records.
Who is thegentlemen?
Thegentlemen is a ransomware operator that maintains a leak site where it lists organizations it claims to have targeted. Such groups commonly employ double-extortion tactics, first encrypting systems and then threatening to release stolen data if a ransom is not paid. Public records show similar actors have targeted educational institutions in multiple countries over recent years, though each listing must be treated as an unverified claim until corroborated by the victim or investigators.
Who is Thammasat University?
Thammasat University is a public research university in Thailand that delivers undergraduate and graduate programs across disciplines including social sciences, humanities, law, and business. Like other higher-education institutions, it maintains records on students, faculty, staff, research activities, and administrative operations. A breach at such an organization can affect individuals whose personal or academic information is held in institutional systems.
What data was at risk
The listing refers only to “internal files exfiltrated in ransomware attack.” No specific categories such as names, identification numbers, financial records, or research data have been disclosed. Universities routinely store enrollment details, academic transcripts, employee records, and limited financial information, but the exact contents of any exfiltrated material in this case remain unconfirmed.
What's at stake
Individuals connected to the university may face risks if their personal information later appears in public dumps or is used for targeted fraud or phishing. The institution itself could encounter operational disruption, regulatory scrutiny, or reputational effects depending on what, if any, data is verified as exposed. Without Reported Details on volume or sensitivity, the concrete impact cannot yet be quantified.
What to do if you're exposed
Monitor official university communications for any guidance on the incident. Change passwords for any accounts linked to the university and enable multi-factor authentication where available. Review financial and academic statements for unusual activity. Readers can run a free exposure scan of their email address against known breach data to check for prior appearances in public listings.

Publicly posted by thegentlemen — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
