On 16 July 2026 the ransomware group thegentlemen listed Mesto Celakovice on its claims site.

Municipal networks continue to appear in ransomware activity because they maintain administrative systems that support essential local services. When a listing appears, it signals that data has left the organisation, even if the precise scope remains unclear.

What happened

The listing states that internal files were exfiltrated in a ransomware attack. No date of intrusion, volume of data, or technical method has been made public. The number of people affected is recorded as unknown.

The group behind it: thegentlemen

Groups of this type typically combine encryption of systems with the threat of data release to encourage payment.

About Mesto Celakovice

Mesto Celakovice is a municipality in the Central Bohemian Region of the Czech Republic, located on the Elbe River roughly 27 kilometres from Prague. It serves approximately 12,000 residents and operates an official website that provides administrative services, local news, and contact points for local government. Organisations of this kind routinely process records related to residents, taxation, property, and public services.

What data was at risk

The published claim refers only to “internal files.” The exact categories of information contained in those files have not been disclosed. Municipal bodies commonly hold personal identifiers, contact details, financial records, and documents submitted for permits or benefits, yet the specific contents exfiltrated in this case remain unconfirmed.

The real-world impact

Residents whose information appears in the exfiltrated files face the possibility of their details circulating among criminal actors, which can lead to targeted fraud or identity misuse over time. For the municipality, the incident may result in operational disruption while systems are restored and in added costs for investigation and remediation. No public statement has yet quantified these effects.
