Sasin Colleges & Universities Listed by thegentlemen Ransomware Group

On February 17, 2026, Sasin School of Management appeared on the leak site of the ransomware group known as thegentlemen. The Bangkok-based graduate business school, Thailand’s first internationally accredited institution of its kind, is claimed to have had internal files exfiltrated during a ransomware attack. Public reporting indicates that the exposed data includes documents that could contain names, contact details, and other records tied to students, alumni, faculty, and staff.

What's Publicly Reported from Reporting

Available reporting describes the incident as a classic ransomware operation: attackers gained access, exfiltrated files, and later listed Sasin on their public leak site when the school did not meet their demands. The listing occurred on February 17, 2026. The volume of data and the exact number of individuals affected remain unknown, but the breach involves internal files rather than a simple credential dump. The school’s public profile on ZoomInfo and its own site confirm it serves thousands of current and former students across MBA, Executive MBA, DBA, and executive education programs.

Why This Matters for You and Your Family

If you or anyone in your household attended Sasin, worked there, or had dealings with the school, your personal information may now sit in a criminal repository. Even when exact victim counts are unknown, ransomware leaks of this type routinely expose names, email addresses, phone numbers, dates of birth, and sometimes passport copies or employment records. Once that information reaches dark-web marketplaces, it can be bought and used for identity theft, phishing campaigns, or harassment. Your family’s exposure does not end at the school’s walls; spouses, children, and shared addresses often become linked through these records.

The Doxxing and Identity-Chain Implications

A single institutional breach rarely stops at the first leak. Criminals chain exposed email addresses to usernames on social media, gaming platforms, and shopping sites. They then map those handles back to real-world identities, phone numbers, and home addresses. This creates a doxxing chain that can lead to targeted harassment, account takeovers, or extortion attempts against you or your children. Credential leaks like this one frequently cascade into gaming account compromises because the same email and password combinations are reused across services. Public reporting shows that families often discover the damage only after a child’s Discord or Roblox account is hijacked using credentials harvested from an old university file.

The Gentlemen Ransomware Group’s Track Record

Public reporting attributes the attack to the ransomware group thegentlemen. The group emerged in recent years and has focused on organizations across education, healthcare, and professional services. Notable prior victims include other academic institutions and mid-sized companies whose internal documents were published after failed ransom negotiations. Their typical playbook involves initial access through phishing or exploited remote desktop services, followed by data exfiltration and extortion via dual-pressure tactics: threatening to publish sensitive files while sometimes encrypting systems. The group maintains a leak site on the dark web where it posts samples and deadlines, a pattern consistent with this Sasin listing.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real identity so you can see exactly what chains back to the Sasin breach.
• Rotate the password you used at Sasin anywhere it is reused and switch on 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure is caught in hours, not months.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that often chain back to the same address or parent email.
• Let remediation specialists handle takedown requests across data brokers and leak sites for you while you focus on securing your own accounts.

The Sasin breach is a reminder that data once considered safely stored inside a university system can surface years later with real consequences for ordinary families. Taking concrete steps now limits how far criminals can travel down the identity chain that begins with this leak. DoxxScan by GalaxyWarden provides continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts—services that directly address the cascading risks shown in incidents like this one.
