Municipality of Posadas Listed by kelvinsecurity Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Municipality of Posadas Listed by kelvinsecurity Ransomware Group (reported May 3, 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.
What happened
The only confirmed public record is the appearance of the Municipality of Posadas on the kelvinsecurity leak site on May 03, 2022. The group claims to have exfiltrated internal files in a ransomware attack. No official statement from the municipality has been referenced in available reporting, and details such as the date of the intrusion, the method of access, or the volume of data remain undisclosed.
Who is kelvinsecurity?
Kelvinsecurity is a ransomware operator that maintains a public leak site where it lists organisations it claims to have targeted. Like other groups in this category, it typically combines file encryption on victim systems with the threat of publishing stolen data. The group’s listings are presented by the operators themselves; independent confirmation of the underlying incidents is not always available.
About Municipality of Posadas
The Municipality of Posadas is the local government authority for the city of Posadas in Argentina. Entities of this type manage public services, citizen records, tax collection, and administrative systems. They routinely process personal information belonging to residents, including identification details, addresses, and records related to municipal services.
What was likely exposed
The listing refers only to “internal files.” The exact categories of data have not been published or verified. Municipal organisations commonly hold resident personal information, tax and payment records, and internal operational documents, but it is not confirmed whether any of these specific types were taken in this case. The number of individuals potentially affected is also unknown.
Why it matters
Local government records often contain information that can be used for identity verification or to target individuals for further fraud. When such data is claimed to have been removed, residents may face increased risk of misuse even if the full scope remains unclear. For the municipality, the incident raises questions about the security of systems that hold public data and the procedures in place for notifying affected people.

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.
