On January 5, 2026, The Structures Group appeared on the leak site of the sinobi ransomware group. The consulting engineering firm, which handles structural engineering, special inspections, forensic analysis, and risk assessments for healthcare, education, justice, and other facilities, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of people whose information may have been exposed remains unknown, any client, employee, vendor, or partner whose records were stored in those systems could now be at risk.

What's Publicly Reported from Reporting
Public reporting indicates that sinobi listed The Structures Group on its dark-web leak page and claims to have stolen internal documents. The firm specializes in independent review plans, due diligence, and structural integrity work across commercial, residential, and institutional projects. No confirmed total of records or specific data fields has been published, but ransomware incidents of this type routinely expose names, addresses, contact details, contracts, project files, and sometimes employee or client personal information. The listing appeared on the sinobi leak site hosted at an onion address tracked by ransomware.live.
Why This Matters for You and Your Family
When an engineering firm like The Structures Group suffers a breach, the information exposed often includes details that connect back to ordinary people. If you or your family have lived or worked in buildings they inspected, hired them for a home addition, or been part of a project they reviewed, your name, address, phone number, or email could be among the files now in attackers’ hands. Internal files exfiltrated in ransomware attacks frequently contain spreadsheets, PDFs, and databases that map real people to real properties. Once that data circulates, it can be sold, combined with other leaks, and used for identity theft, phishing, or harassment. Your family does not need to be the primary target for your information to become part of a larger data set available to criminals.
The Doxxing and Identity-Chain Implications
Leaked internal files rarely stay isolated. A single address, email, or project reference can link your professional identity to your home, your children’s schools, or even family members’ names. Attackers chain these fragments together: an engineering report might list a homeowner’s email, which matches a credential from an earlier breach, which then reveals a gaming username. This creates a doxxing chain that can lead to account takeovers, swatting, or targeted scams. Credential leaks like this one routinely cascade into gaming account compromises because the same email and password combinations are reused across work, personal life, and children’s online profiles.
