Genrose Stone + Tile Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Genrose Stone + Tile was listed by the sinobi ransomware group on November 17, 2025, after internal files were exfiltrated in a ransomware attack. An undisclosed number of people may be affected; anyone who has shared data with the company should review their accounts and consider additional security steps.
Inside the incident
The incident centers on a claim posted by the sinobi group that it obtained internal files from Genrose Stone + Tile. The date the listing appeared is November 17, 2025. No information has been released on the method of access, the volume of data taken, or whether any systems were encrypted. The organization has not issued a public statement confirming or denying the listing.
The group behind it: sinobi
Sinobi is a ransomware operator that maintains a leak site where it lists organizations it claims to have targeted. The group typically posts samples or descriptions of data it says were removed from victim networks before encryption demands are made. Public reporting on the actor shows repeated use of this approach across multiple sectors, though each listing remains an unverified claim until independently confirmed.
About Genrose Stone + Tile
Genrose Stone + Tile has operated since 1988 as a supplier of natural stone and tile products. The company works with homeowners, architects, and designers, sourcing materials and providing support for residential and commercial projects. Organizations in this sector routinely maintain records that include customer project details, supplier contracts, and internal operational documents.
The information in question
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific file types or data categories has been released. The exact contents therefore remain unconfirmed.
The real-world impact
Exposure of internal files can create operational and privacy risks for the organization and any individuals whose information appears in those records. Without a confirmed list of data elements, the precise consequences for customers or employees cannot be assessed from public sources.
What to do if you're exposed
Individuals concerned about possible exposure should monitor accounts for unusual activity and consider placing fraud alerts with credit bureaus. Organizations in similar situations often engage incident-response specialists to review access logs and determine notification obligations.
- Change passwords for any accounts linked to the organization.
- Review bank and credit statements for unauthorized transactions.
- Run a free exposure scan of your email address against known breach data.

Publicly posted by sinobi — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
