Homestead Electrical Contracting Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Homestead Electrical Contracting was listed by the sinobi ransomware group on December 18, 2025, with internal files reported as exfiltrated. An undisclosed number of individuals may be affected; anyone who has shared personal information with the company should verify their exposure and consider protective steps.
Breaking down the breach
The only confirmed detail is the December 18, 2025 listing on the group’s site. No information has been released about the date of the intrusion, the method of access, the volume of data taken, or whether any systems were encrypted. The scale of exposure and the number of people or entities impacted remain unknown.
The group behind it: sinobi
Sinobi is a ransomware operator that maintains a public leak site where it lists organizations it claims to have compromised. The group’s typical pattern involves exfiltrating data and then posting samples or directories to pressure victims. Its listings are presented as claims by the group; independent confirmation of the underlying events is not provided in the available record.
Homestead Electrical Contracting and its sector
Homestead Electrical Contracting, LLC has operated since 1981, delivering electrical design and build services, high-voltage work, fire-alarm installation, and 24/7 maintenance. Its clients have included Walgreens Corporation and Lake County Water Reclamation District. Electrical contractors routinely hold project documentation, client contact records, and system configuration details that support critical facilities.
The information in question
The listing refers only to “internal files exfiltrated.” No inventory of specific file types, client records, or personal data has been published. Organizations in this sector commonly store employee information, vendor contracts, and site diagrams, yet the precise contents of the exfiltrated material have not been confirmed.
What's at stake
Exposed internal files can reveal operational procedures and client relationships that may be reused in further targeting. For individuals whose details appear in contractor records, the main concerns are secondary misuse of contact information or credentials. The organization faces potential follow-on operational disruption and the cost of investigation and remediation.
If your data was in this claimed breach
Individuals can take the following steps:
- Monitor financial and email accounts for unusual activity.
- Change passwords for any accounts linked to the contractor and enable multi-factor authentication.

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.
