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

On January 20, 2026, the Czech company Garko appeared on a listing associated with the ransomware group thegentlemen. The entry states that internal files were exfiltrated during a ransomware attack, though the number of individuals affected and the precise contents of those files remain undisclosed. Public reporting provides no further confirmation of the incident or its scope.

Such listings have become a recurring feature of the current threat landscape, where ransomware operators publish victim names on dedicated sites to pressure organizations into paying ransoms. The absence of verified details leaves the practical impact on Garko’s customers and partners difficult to assess at present.

What happened

The only confirmed public information is the January 20, 2026 listing of Garko by thegentlemen. The group’s post indicates that internal files were taken in a ransomware operation. No dates for the intrusion itself, no volume of data, and no ransom demand figures have been released by either the organization or the group. The number of people whose information may be involved is reported as unknown.

Who is thegentlemen?

Thegentlemen is a ransomware operator that follows the double-extortion model common among current groups. After encrypting systems, actors of this type frequently copy data and threaten its release on a leak site if payment is not received. Public records show similar groups maintaining lists of claimed victims and releasing samples or directories to demonstrate possession of files. Attribution in any single case rests on the group’s own claims unless independently verified by investigators or the victim.

About Garko

Garko is a Brno-based firm that produces custom prizes, trophies, medals, and certificates for sports competitions and cultural events. Its clients range from small local tournaments to larger regional organizers. Organizations in this sector routinely collect names, contact details, and event-related information from participants and ordering customers, along with internal records on production, pricing, and supplier arrangements.

The information in question

The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific data categories has been published. Companies of this type commonly store customer names, addresses, order histories, and payment references, as well as employee records and design files. Until Garko or an authoritative investigation releases further details, the exact nature of the material remains unconfirmed.

Why it matters

Exposure of internal files can create downstream risks for individuals whose names or contact information appear in orders or event records. For the organization, the incident may disrupt operations and require forensic review, system restoration, and notification processes. Where personal data is involved, affected people may face increased attempts at phishing or account misuse, though the scale of any such exposure is not yet known.

What to do if you're exposed

Individuals who have ordered from Garko or participated in events it supported should monitor their email and financial accounts for unusual activity. Enabling multi-factor authentication on any associated services and using unique passwords remain basic protective steps. Readers can run a free exposure scan of their email address against known breach data to check whether their information has appeared in previously published datasets.
