TWU Local 100 Listed by qilin Ransomware Group

On February 3, 2026, the qilin ransomware group added TWU Local 100 to its public leak site, claiming to have stolen internal files from the New York City transit workers union.

What's Publicly Reported from Reporting

Public reporting indicates the union appeared on the qilin leak site with a notice that internal data had been exfiltrated. The exact number of people affected remains unknown because the sample files released so far do not include membership lists or personal records. Available reporting describes the incident as a ransomware attack in which the group first encrypted systems and then threatened to publish stolen documents unless a ransom was paid. No deadline for the current leak has been publicly confirmed, but qilin typically escalates pressure by releasing additional batches of data over days or weeks.

Why This Matters for You and Your Family

When a union local like TWU Local 100 is hit, the information inside its systems often includes names, addresses, Social Security numbers, payroll details, and contact information for thousands of working families. If your email, phone number, or address appears in those files, criminals can use it to file fraudulent tax returns, open accounts in your name, or target your family with phishing attacks. Even if you are not a TWU member, credential leaks from any organization frequently cascade into personal email and banking accounts when people reuse the same passwords across work and home.

Internal files exposed in these incidents regularly contain scanned documents, spreadsheets, and emails that reveal family relationships, children’s names, and dates of birth. Once that information reaches dark-web marketplaces, it becomes raw material for identity theft that can follow you for years.

The Doxxing and Identity-Chain Implications

Ransomware leaks rarely stop at one dataset. Criminals combine the newly released union files with earlier breaches to build detailed profiles. A single leaked work email can be linked to your personal social-media accounts, your children’s gaming usernames, and household addresses. This identity-chain process turns one breach into multiple attack surfaces. Public reporting shows that qilin and similar groups often sell or publish data in batches, giving other criminals time to cross-reference it with records from retail breaches, fitness apps, and school systems. The result is a map that can lead directly to your doorstep or your child’s online identity.

Qilin’s Publicly Known Track Record

Public reporting attributes the qilin ransomware group’s emergence to 2022. It has since targeted hospitals, manufacturers, local governments, and unions. Notable prior victims include healthcare providers and critical infrastructure organizations whose data appeared on the same leak site. The group’s typical playbook begins with initial access through phishing or stolen credentials, followed by lateral movement inside the network, encryption of systems, and exfiltration of sensitive files. Extortion combines ransom demands with the public shaming of victims on its leak site, releasing small samples first and threatening larger dumps if payment is not received.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup to remove what you can.
• Rotate any password you ever used at TWU Local 100 or related union systems, and enable 2FA through an authenticator app everywhere that password was reused.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information surfaces you learn within hours rather than 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 while you focus on securing your own accounts.
