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 on the LockBit3 leak site describes OSSC Mexico as a company founded in 2008 that specializes in GIRO payroll software. The group claims to have exfiltrated internal files during a ransomware attack. The exact number of people whose information appears in the stolen data remains unknown. Available reporting does not specify which exact systems were compromised or list the precise categories of personal information exposed. The posting appeared on the LockBit3 onion site, with mirrors tracked by ransomware.live.
Why This Matters for You and Your Family
When a payroll software provider is breached, the data stolen often includes employee records, tax identifiers, banking details, and contact information for individuals and the companies they work for. If you or anyone in your household has ever received payroll services from a company using OSSC Mexico’s GIRO software, your personal details may now sit in a ransomware leak. Stolen payroll files can be used to file fraudulent tax returns, open accounts in your name, or launch targeted phishing attacks against you and your family. Children’s information linked to a parent’s employment record can also surface in these leaks, creating long-term risks.
The Doxxing and Identity-Chain Risks
Ransomware groups rarely stop at posting raw files. Once internal documents are public, other criminals scrape names, emails, phone numbers, and addresses to build detailed profiles. These profiles are then sold or used to link your work identity to personal accounts across social media, gaming platforms, and shopping sites. A single leaked work email can chain to your family’s shared password habits, leading to account takeovers on streaming services, school portals, or children’s gaming accounts. Public reporting indicates that such credential leaks frequently cascade into full doxxing campaigns where attackers publish home addresses, phone numbers, and family relationships to increase pressure or enable identity theft.
