Coralina Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On April 26, 2026, the ransomware group thegentlemen listed Coralina on its site and stated that internal files had been taken during a ransomware operation. The number of people whose information may be involved is not known, and no further details about the scale or timing of the incident have been made public. The listing places Coralina among the organisations the group has named in connection with its activities. Public records show no independent confirmation of the data access at this stage.

Breaking down the breach

The only confirmed public information is the April 26, 2026 listing itself. The group claims internal files were exfiltrated. No figure has been released for the volume of data, the number of records, or the date of the alleged intrusion. Coralina has not issued a public statement on the matter, and no regulatory filing or law-enforcement notice has disclosed additional technical details.

Who is thegentlemen?

Thegentlemen is a ransomware group that maintains a leak site where it lists organisations it claims to have targeted. Like other groups of this type, it typically seeks to obtain data and then pressures the victim for payment in exchange for not publishing the material. Public reporting on the group’s prior listings shows a pattern of naming both private companies and public-sector entities, though each claim requires separate verification.

Who is Coralina?

Coralina, formally the Corporación para el Desarrollo Sostenible del Archipiélago de San Andrés, Providencia y Santa Catalina, is Colombia’s official environmental authority for the San Andrés, Providencia and Santa Catalina archipelago. Established by Article 37 of Law 99 of 1993, it functions as a public body with administrative and financial autonomy. Its responsibilities include the management and protection of natural resources in the Caribbean territory under its jurisdiction.

The information in question

The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific data categories has been published. Organisations of this type routinely hold administrative records, environmental monitoring data, permitting documents, financial information related to public budgets, and correspondence with other government agencies. The precise contents of any material taken remain unconfirmed.

The real-world impact

For individuals, the main concern is the possible exposure of personal details contained in routine government files, such as names, contact information or identifiers linked to environmental permits or administrative processes. For the organisation, the incident adds to the operational burden of investigating the access, notifying oversight bodies if required, and restoring systems. Government environmental agencies hold data that can affect regulatory decisions and local communities; any prolonged uncertainty about the integrity of those records can slow public decision-making.

If your data was in this claimed breach

Monitor official statements from Coralina and any notices issued by Colombian data-protection authorities. Review bank and government accounts for unusual activity and consider placing fraud alerts where available. Individuals can also run a free exposure scan of their email address against known breach data to check whether their information appears in previously published lists.
