Western Slope Iron & Supply Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Western Slope Iron & Supply was listed by the sinobi ransomware group on February 05, 2026, with internal files reported to have been exfiltrated; the date of the intrusion has not been established. Anyone who has shared information with the company should review their accounts and monitor for suspicious activity.
Inside the incident
Public reporting on the event is limited to the February 5, 2026 listing on the sinobi leak site. The entry claims that files were taken from Western Slope Iron & Supply during a ransomware operation. No confirmation of the claim has been issued by the company, and no independent verification of the data’s authenticity or scope has been released. The date the intrusion began, the method of initial access, and whether encryption was also deployed are not disclosed in available information.
Who is sinobi?
Sinobi is a ransomware group that has appeared on leak sites in recent years. Such groups commonly gain access through phishing, remote-desktop vulnerabilities, or compromised credentials, then move laterally inside networks to locate and copy data before deploying encryption. When ransom demands are not met, operators sometimes publish samples or indexes of stolen material on dedicated sites to pressure victims. The group’s listing of Western Slope Iron & Supply constitutes an unverified claim by the actor; no independent confirmation of the data’s origin or completeness has been established.
Who is Western Slope Iron & Supply?
Western Slope Iron & Supply, Inc. has operated since 1974 as a certified steel fabricator in Grand Junction, Colorado. The firm produces structural and miscellaneous steel for commercial, industrial, residential, and governmental projects across the Western United States and also distributes Hilti products. Organizations of this type routinely maintain records that include project specifications, supplier and subcontractor details, employee information, and client contact data. A breach at such a company can therefore touch entities beyond the firm itself, including public-sector clients and private construction partners.
What data was at risk
The only data type named in connection with the listing is “internal files exfiltrated in ransomware attack.” No inventory of file categories, record counts, or time periods covered has been released. Companies in steel fabrication and distribution typically store contracts, engineering drawings, payroll records, vendor lists, and project correspondence. Whether any of these categories are present in the claimed exfiltration cannot be confirmed from public information.
The real-world impact
Exposure of internal files can lead to follow-on fraud attempts, targeted phishing, or misuse of project details by third parties. Clients and employees may receive unsolicited contact that references information drawn from the records. For the organization, the incident adds costs for investigation, potential legal review, and remediation of access controls. Because the number of affected individuals is unknown, the scale of personal exposure cannot yet be measured.
If your data was in this claimed breach
Monitor bank, credit, and benefits accounts for unusual activity. Enable multi-factor authentication on any accounts that still rely on passwords alone. Request copies of your credit reports from the major bureaus to check for unauthorized inquiries or new accounts. A free exposure scan of your email address against known breach data can indicate whether your information has appeared in previously published sets; repeat the check periodically as new listings surface.

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.
