kraslice.cz Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 25, 2025, the domain kraslice.cz appeared on a listing associated with the lockbit5 ransomware group. The entry states that internal files were exfiltrated during a ransomware attack against the municipal office of Kraslice, a town in the Czech Republic. No information has been released on the number of individuals affected, the volume of data involved, or whether any material has been published. The incident fits a pattern in which ransomware operators continue to target public-sector entities even as law-enforcement actions against such groups have increased in recent years. Public disclosure remains limited to the listing itself.

Breaking down the breach

The only confirmed detail is the appearance of kraslice.cz on the lockbit5 listing on 25 December 2025. The entry describes the theft of internal files but supplies no further metrics. The number of people potentially affected, the date of any intrusion, and the method of initial access have not been disclosed by the municipality or by investigators.

The group behind it: lockbit5

Lockbit5 is a ransomware operation that has been active for several years and is known for encrypting systems and threatening to release stolen data. The group maintains a leak site where it lists victims and, in some cases, posts samples of material. Its listings constitute claims by the operator; independent confirmation of the underlying incidents is not always available at the time of publication.

kraslice.cz and its sector

kraslice.cz is the public website of Městský úřad Kraslice, the municipal authority serving the town of Kraslice. Local government offices routinely process resident records, tax and property information, social-service data, and correspondence with citizens. Because these entities hold personal and administrative information tied to daily public services, any compromise can affect a defined local population even when the total number of records remains unknown.

What was likely exposed

The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific data categories has been published. Organisations of this type commonly store personal identifiers, contact details, financial or benefit records, and internal administrative documents. The precise contents of the exfiltrated material are unconfirmed.

The real-world impact

Residents of Kraslice may face risks of identity misuse or targeted fraud if personal information from municipal files is later released. The municipality itself could encounter operational disruption and costs associated with investigation and system restoration. At present, the scale of any such consequences cannot be quantified from publicly available information.

What to do if you're exposed

Individuals concerned about possible exposure should monitor their financial accounts and official correspondence for unusual activity. Enabling multi-factor authentication on government and financial services accounts reduces the value of stolen credentials. Readers may also run a free exposure scan of their email address against known breach data to determine whether their information has appeared in previously published datasets.
