St Thomas More Catholic High School Listed by qilin Ransomware Group

On June 3, 2025, St. Thomas More Catholic High School in Lafayette, Louisiana, appeared on the leak site of the qilin ransomware group. The attackers claim to have exfiltrated internal files from the prestigious K-12 institution, exposing data that could belong to students, parents, alumni, and staff.

What's Publicly Reported from Reporting

Public reporting indicates the school was listed on the qilin ransomware group's dedicated leak portal. The entry states that internal files were taken during a ransomware incident. No exact victim count has been released, and the precise volume or specific types of records remain unconfirmed in available reporting. The listing appeared on the group's onion site, which is tracked by ransomware monitoring services such as ransomware.live.

June 3, 2025 marks the public disclosure date on the leak site. The school has not yet issued a detailed public statement confirming the breach scope, though its status as a listed victim is now part of the public record.

Why This Matters for You and Your Family

If you or your children attend or have attended St. Thomas More Catholic High School, your personal information may now sit in a ransomware group's hands. School records frequently contain full names, dates of birth, addresses, parent contact details, medical notes, academic transcripts, and sometimes Social Security numbers or banking information for tuition payments. Once stolen, this data rarely stays contained.

Internal files from a high school are especially sensitive because they tie together family identities across multiple generations and locations. A single leak can give criminals the starting point they need to target your household for identity theft, phishing, or harassment. For families who chose this school precisely for its safe, close-knit environment, the breach represents a direct erosion of that privacy.

The Doxxing and Identity-Chain Implications

Ransomware groups like qilin do not always publish every file immediately. They often keep stolen data for further exploitation or sale on underground forums. Even partial leaks can trigger doxxing chains: an email address from a school directory links to a reused password, which leads to a compromised social-media account, which reveals children's names, photos, and gaming handles. These connections allow attackers to build detailed profiles that follow your family across platforms.

Credential leaks like this one cascade into account takeovers on gaming services, email, and financial portals. Children's gaming accounts are particularly vulnerable because parents often reuse credentials or use family email addresses. A breach at a school can therefore expose an entire household's digital footprint, turning one incident into months or years of potential harassment and fraud.

Qilin's Publicly Known Track Record

Public reporting attributes the attack to the qilin ransomware group, which emerged in 2022. The group has targeted hospitals, schools, municipalities, and private businesses across multiple countries. Its typical playbook involves gaining initial access through phishing or exploited remote desktop protocols, exfiltrating data before deploying ransomware, then publishing samples on its leak site when victims refuse to pay. Qilin uses double-extortion tactics: it threatens both operational disruption and public release of sensitive files. Exact success rates are difficult to verify, but education-sector victims have appeared repeatedly in its listings.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then complete the cleanup of exposed records.
• Rotate any password used at the school anywhere it is reused, and switch to 2FA through an authenticator app rather than text messages.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your family's data 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 addresses and credentials.
• Let remediation specialists handle takedown requests across data brokers and leak sites while you focus on securing accounts and talking with your family about safe online habits.
