Croft Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Croft was listed by the sinobi ransomware group on November 19, 2025, after internal files were exfiltrated in a ransomware attack. The number of people affected has not been disclosed; anyone connected with Croft should check whether their data was exposed and take protective steps.
Inside the incident
The only confirmed information is the group’s listing of Croft and its assertion that internal files were taken. No date of the intrusion, volume of data, or confirmation of encryption has been disclosed. The company has not issued a public statement detailing its response or the extent of any operational disruption.
Inside sinobi
Sinobi is a ransomware operation that maintains a leak site to publish names of organizations it claims to have targeted. The group typically combines file encryption with data exfiltration and then uses the threat of public release to pressure victims. Its listings are presented by the group itself; independent confirmation of each claim is not always available at the time of posting.
Who is Croft?
Croft is a window and door manufacturer established in 1920 that produces energy-efficient vinyl and aluminum products for residential use. It supplies both individual homeowners and certified dealers and positions itself as one of the larger firms in its sector. Organizations of this type routinely maintain records on customers, suppliers, product specifications, and internal operations.
What was likely exposed
The group’s listing refers only to “internal files.” No inventory of specific record types or data categories has been published. Companies in manufacturing commonly store customer order details, dealer information, financial records, and product design data, but the exact contents allegedly taken from Croft remain unconfirmed.
Why it matters
Internal files can contain information that identifies customers or business partners, which may later appear in further criminal activity if released. For the organization, the incident adds costs for investigation, potential regulatory reporting, and restoration of systems. Individuals whose details are held by such suppliers face the ordinary risks associated with any exposure of contact or transaction records.
Were you affected?
Begin by monitoring official statements from Croft for any customer notification. Review bank and credit accounts for unusual activity and consider placing a fraud alert if personal identifiers were likely involved. A short list of immediate steps follows:
- Run a free exposure scan of your email address against known breach data.
- Change passwords for any accounts linked to Croft or similar suppliers.
- Enable multi-factor authentication on financial and email services.

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.
