Instituto Meteorológico Nacional Listed by conti Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Instituto Meteorológico Nacional Listed by conti Ransomware Group (reported April 19, 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 Instituto Meteorológico Nacional on the Conti group’s leak site on 19 April 2022. The group claims to have exfiltrated internal files. No independent confirmation of the volume of data, the encryption of systems, or any ransom demand has been made public. Details on the initial access method and the timeline of the intrusion are not available.
Who is conti?
Conti is a ransomware operation that conducted numerous attacks between 2020 and 2022. It followed a double-extortion model in which data were copied before encryption, and the threat of publication was used to pressure victims. The group maintained a public leak site to list organisations that had not met its demands. Conti’s infrastructure was disrupted in mid-2022, after which its operators largely ceased activity under that name.
About Instituto Meteorológico Nacional
Instituto Meteorológico Nacional is Costa Rica’s national meteorological service. It collects, analyses and disseminates weather and climate observations, issues forecasts and warnings, and maintains long-term environmental records. Organisations of this type routinely store operational logs, sensor data, internal administrative files and limited personal information relating to staff or registered users of public services.
What was likely exposed
The Conti listing refers only to “internal files.” No inventory of specific data categories has been published. Meteorological institutes commonly hold records that include employee contact details, network diagrams, research datasets and administrative correspondence. Whether any of these categories were among the material listed by the group has not been confirmed.
Why it matters
Exposure of internal operational files can reveal details about an organisation’s infrastructure and procedures. For a national weather service, such information may affect the continuity of forecasting operations and the protection of long-term climate records. Individuals whose data appear in administrative files face the ordinary risks associated with the circulation of contact details or employment records, though the scale of any such exposure remains unknown.

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.
