Caldes de Montbui Listed by vicesociety Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Caldes de Montbui Listed by vicesociety Ransomware Group (reported May 11, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
On May 11, 2022, the municipality of Caldes de Montbui appeared on the leak site maintained by the ransomware group vicesociety. The listing states that internal files were taken during a ransomware operation, though the number of individuals affected and the precise contents of the material remain undisclosed.
The incident is significant because Caldes de Montbui is a local government body that maintains records on residents and municipal operations. Any confirmed exposure of such data would affect ordinary citizens whose information is held for routine administrative purposes.
What happened
Caldes de Montbui was listed on vicesociety’s ransomware leak site on May 11, 2022. The group claims to have stolen internal data during a ransomware attack. No further details on the timing of the intrusion, the volume of material taken, or the method of access have been made public.
Who is vicesociety?
Vicesociety is a ransomware operator that maintains a public leak site to publish data taken from victims who do not pay a ransom demand. The group typically gains access through common intrusion techniques, deploys encryption on targeted systems, and then threatens to release exfiltrated files. Its listings have included both private companies and public-sector organisations in multiple countries.
About Caldes de Montbui
Caldes de Montbui is a municipality in Spain that delivers local government services. Organisations of this type routinely collect and store personal information from residents, including identification details, tax and payment records, and documentation related to permits, social services, and property. A breach at such an entity can therefore involve data that citizens are required to provide in order to receive public services.
What was likely exposed
The only information released states that internal files were exfiltrated. The exact categories of data contained in those files have not been disclosed. Municipalities of this kind commonly hold personal identifiers, contact information, financial records, and administrative correspondence, but it is not confirmed whether any of these specific types of information were among the material listed by the group.
Why it matters
Local government records often contain data that cannot easily be changed, such as names, addresses, and official identifiers. If the exfiltrated files include such information, affected individuals could face risks of targeted fraud or unwanted disclosure of personal circumstances. For the municipality, the incident may require additional resources for investigation, notification, and system remediation.
If your data was in this claimed breach

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.
