Adirondack Networks Listed by nightspire Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Adirondack Networks was listed by the nightspire ransomware group on February 14, 2026, after internal files were exfiltrated in a ransomware attack; the date of the intrusion is not established. Anyone who may have shared data with the company should check for notifications and review account security.
Inside the incident
The only confirmed information is the listing itself and the group’s statement that internal files were allegedly exfiltrated during a ransomware operation. No date of the intrusion, no count of records, and no description of the attack method have been released by Adirondack Networks or by investigators. The organization has not issued a public statement confirming or disputing the claim.
Inside nightspire
Nightspire is a ransomware operation that follows the common pattern of encrypting systems and then threatening to publish stolen data unless a ransom is paid. The group maintains a leak site where it lists victims and posts samples of material it says it has taken. Such listings are claims made by the group; independent confirmation of the data’s authenticity or completeness is rarely available at the time of posting.
Who is Adirondack Networks?
Adirondack Networks provides network and technology services, primarily to businesses and institutions in its region. Organizations of this type routinely manage client connections, store configuration records, and hold administrative documentation that can include contact details and access credentials for the networks they support.
What was likely exposed
The listing refers only to “internal documents” and “internal files.” No specific categories of personal or customer data have been named. Companies in the network-services sector commonly retain records such as client contact information, service agreements, and system credentials, yet the exact contents of the material claimed in this case remain unconfirmed.
Why it matters
Internal documents from a network provider can contain details that affect both the organization and its clients, including information that could be used for further targeting or unauthorized access. When the scale and nature of the data are not disclosed, individuals and businesses connected to the provider have no clear way to assess their own exposure.
What to do if you're exposed
Review any accounts or services linked to Adirondack Networks and change passwords if you have not done so recently. Enable multi-factor authentication on those accounts and monitor bank and credit statements for unusual activity. You can run a free exposure scan of your email address against known breach data to see whether your information appears in public listings from this or other incidents.

Publicly posted by nightspire — 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.
