Ubon Ratchathani University Listed by Blacklock Ransomware Group

If you are a student of Ubon Ratchathani University, here’s what is being claimed, and what it would mean for you.

Colleges & Universities Thailand 502 Employees Ubon Ratchathani University (UBU) (Thai, ) was established as a campus of Khon Kaen University, Thailand, in 1987. It gained independent university status in 1990. Revenue $38.7 Million

Ubon Ratchathani University Listed by Blacklock Ransomware Group

On June 26, 2025, Ubon Ratchathani University appeared on the leak site of the BlackLock ransomware group. The Thai public university with roughly 502 employees is claimed to have had internal files exfiltrated after a ransomware attack. Anyone connected to the institution — students, faculty, staff, alumni, or their families — may now find personal information circulating in criminal circles.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates that BlackLock operators published a data sample and announced the breach on their dark-web leak site. The exposed material consists of internal files rather than a single structured database. No precise victim count has been released, and the university has not yet issued a public statement detailing the scope. The leak site link points to files previously hosted under the e-tech.ac.th domain, which appears tied to the university’s technical infrastructure. Available reporting describes the incident as a classic ransomware pattern: encryption followed by data exfiltration and extortion pressure.

Why This Matters for You and Your Family

Universities hold sensitive records on thousands of people. Even if you are not a current student or employee, your data may have been collected years ago when you applied, enrolled, received financial aid, or participated in alumni programs. Names, addresses, phone numbers, email accounts, dates of birth, and national ID numbers are common in university systems. When these details surface on a ransomware leak site, they become raw material for identity theft, phishing campaigns, and long-term harassment. Your family members — including children who may have attended summer programs or used university Wi-Fi — can also be pulled into the same exposure chain.

Once information leaves an institution’s control, it never truly disappears. Copies spread across forums, marketplaces, and private chat groups. The breach therefore affects not just the 502 employees but an extended circle of past and present affiliates and their households.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
