Who is kelvinsecurity?
Kelvinsecurity is a ransomware operation that maintains a public leak site where it lists organizations it claims to have targeted. Like other groups in this category, it typically pairs file encryption on victim systems with the exfiltration of data, then uses the threat of publication to pressure payment. The group has appeared in multiple prior listings involving entities in various countries, following a pattern of announcing claimed breaches on its site.
In this case the group claims to have obtained internal data from NATION Costa Rica; that claim has not been independently verified in public reporting.
About NATION Costa Rica
NATION Costa Rica is an organization based in Costa Rica. Entities of this type commonly maintain internal records that can include operational documents, communications, and administrative files. A breach involving such an organization is consequential because the data held often relates to the entity's own activities and any individuals or partners connected to it.
What was likely exposed
The only data type named in connection with the listing is internal files exfiltrated during the ransomware attack. The group states that it stole internal data, but no inventory of specific file categories or records has been released. The exact contents therefore remain unconfirmed.
Why it matters
When internal files are taken, the primary risks involve potential misuse of any operational or personal information those files contain. Individuals connected to the organization could face follow-on fraud or targeted scams if their details appear in the material. For the organization itself, exposure of internal records can complicate ongoing operations and require additional security measures.
Because the scale and specific data elements are not publicly detailed, the full extent of these risks cannot be quantified from available information.
If your data was in this claimed breach
Monitor bank and email accounts for unusual activity and consider enabling multi-factor authentication on services that support it. Change passwords for any accounts that may have reused credentials mentioned in the exposed files. Individuals can also run a free exposure scan of their email address against known breach data to check for appearances in public listings.

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.
