Váhostav Listed by dragonforce Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Váhostav was listed by the dragonforce ransomware group on 21 December 2025 after internal files were exfiltrated in a ransomware attack; the number of people affected remains undisclosed and the actual date of the intrusion has not been established. Individuals should check whether their data was exposed and take steps to protect themselves.
Breaking down the breach
The only confirmed information is the listing itself and the claim that internal files were exfiltrated. No date of the intrusion, no count of affected records and no description of the attack method have been released. The organisation has not issued a public statement confirming or denying the incident, and the exact status of any data remains unverified beyond the group’s assertion.
The group behind it: dragonforce
Dragonforce is a ransomware operation that follows the common pattern of stealing data before encrypting systems, then using the threat of publication to press for payment. The group maintains a leak site where it lists victims and, in some cases, posts samples of material. Its listing of Váhostav constitutes a claim by the group; independent confirmation of the data’s authenticity or extent has not been reported.
Váhostav and its sector
Váhostav is one of the larger construction firms in Slovakia, undertaking technically complex work in transport, engineering and industrial projects both inside the country and abroad. The company maintains its own production facilities and subsidiaries and holds ISO certifications covering quality, safety and environmental management. Construction companies routinely store records relating to employees, subcontractors, equipment, project specifications and regulatory compliance.
What was likely exposed
The group states that internal files were removed. No inventory of file types or data categories has been published. Organisations of this kind typically hold employee contact details, payroll information, supplier contracts, technical drawings and correspondence. Whether any of these categories are present in the material claimed by dragonforce is not confirmed.
The real-world impact
Individuals whose records appear in internal files could face risks of targeted phishing, identity misuse or unwanted disclosure of employment or financial details. For the company, the incident adds operational pressure at a time when project delivery, regulatory reporting and partner relationships already require careful data handling. The absence of Reported Details means affected people cannot yet assess the precise level of exposure.
Were you affected?
Begin by monitoring official statements from Váhostav and any notifications sent to employees or partners. Run a free exposure scan of your email address against known breach data and review bank, tax and government accounts for unusual activity. Keep software updated and use strong, unique passwords with multi-factor authentication on any accounts linked to the company.

Publicly posted by dragonforce — 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.
