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.

Reported Details of the Breach
Public reporting indicates the attackers exfiltrated internal files containing client personal document scans, employee personal information, HR records, clients’ financials, credit card details, payment information, NDAs, confidentiality agreements, legal and court documents, and police reports. The firm, which has offered income tax preparation and advice for 27 years, appears to have been compromised in a ransomware incident. The exact number of individuals affected remains unknown. The group has stated it will upload the full 82 GB archive in the near future.
Why This Matters for You and Your Family
If you or anyone in your household has used Elliott Tax Service, your sensitive financial and personal records may now sit on a criminal leak site. Tax documents often contain Social Security numbers, addresses, income details, and banking information that criminals can weaponize for identity theft, fraudulent tax filings, or account takeovers. Even if you were not a direct client, family members or dependents whose information appears in shared records could be exposed. Once data reaches ransomware leak sites, it spreads quickly through underground marketplaces, increasing the chance that someone will target you or your family months or years later.
The Doxxing and Identity-Chain Risks
Stolen tax and financial files frequently serve as the foundation for larger doxxing campaigns. A single leaked document can link your name, address, date of birth, and phone number to email accounts, usernames, and passwords reused across other services. Attackers then follow these connections to gaming accounts, social media profiles, and cloud storage, building a complete identity chain. Credential leaks like this one regularly cascade into account takeovers, especially for gaming platforms popular with children and teenagers. What begins as a tax firm breach can therefore expose your entire digital footprint and that of your family.
