The incident was disclosed on December 16, 2025, and an undisclosed number of individuals may have been affected; anyone connected to the company should verify their exposure and take appropriate protective steps.
What happened
The only confirmed information is the listing itself. Nightspire posted International Door, Inc. as a victim and asserted that internal files were exfiltrated. The number of individuals potentially impacted is listed as unknown, and no additional technical details about the intrusion method, encryption status, or data volume have been released by the company or the group.
Inside nightspire
Nightspire operates as a ransomware group that uses data exfiltration alongside encryption to pressure victims. Like similar actors, it maintains a leak site where it lists organizations and publishes samples or claims of stolen material when negotiations stall. The group’s listing of International Door, Inc. constitutes its public claim of involvement; independent confirmation of the data’s contents or the attack’s scope has not been provided.
Who is International Door, Inc?
International Door, Inc. operates in the commercial and industrial door sector, supplying and installing entry systems for buildings. Organizations of this type routinely maintain records on employees, customers, vendors, and project specifications. A breach affecting such a company can expose operational documents and personal information tied to contracts and personnel, even when the precise files remain undisclosed.
The information in question
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific data categories has been published. Companies in this sector commonly store employee records, customer contact details, financial documentation, and installation or maintenance files; however, the exact contents of the claimed exfiltration have not been verified or itemized.
What's at stake
Exposed internal files can contain personal identifiers, contract terms, or operational details that enable targeted fraud or further social-engineering attempts against individuals connected to the company. For the organization, the incident adds to the costs of investigation, potential regulatory notifications, and remediation. Because the number of affected people and the sensitivity of the files remain unknown, the full scope of downstream consequences cannot yet be measured.
What to do if you're exposed
Individuals who have done business with or worked for International Door, Inc. should monitor their accounts for unusual activity and consider placing fraud alerts with credit bureaus. Changing passwords for any associated services and enabling multi-factor authentication are immediate steps.

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.
