Zabun Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Zabun was listed by thegentlemen ransomware group on February 26, 2026, after internal files were exfiltrated in a ransomware attack that affected an undisclosed number of people. Individuals are advised to check whether their information has been exposed and to take any recommended protective steps.
On February 26, 2026, the ransomware group thegentlemen listed Zabun on its leak site, claiming to have exfiltrated internal files during a ransomware attack. The number of people affected remains unknown, and no further details on the volume or contents of the data have been made public. The incident adds to the pattern of ransomware operations that continue to target mid-sized commercial organisations across Europe and beyond.
What happened
The listing indicates that thegentlemen asserts it carried out a ransomware intrusion against Zabun and removed internal files. No confirmation of the claim has been issued by Zabun, and the company has not disclosed whether it received a ransom demand or whether any systems were encrypted. The scale of the operation, the precise date of the intrusion, and the method of initial access are not stated in the available information.
Who is thegentlemen?
Thegentlemen is a ransomware group that maintains a leak site to publish data it claims to have stolen from victims that refuse to pay. Such groups typically gain access through phishing, exposed remote services, or compromised credentials, then move laterally to locate and exfiltrate files before deploying encryption. The listing of Zabun follows the group’s established practice of naming organisations publicly after an attack.
About Zabun
Zabun, operating as Zabun Grup, specialises in the design and construction of exhibition stands for trade fairs. The company maintains operations in Turkey and several European locations, working on both domestic and international projects that involve client branding, stand fabrication, and on-site installation. Organisations in this sector routinely handle project specifications, supplier contracts, client contact details, and financial records tied to multi-month exhibition cycles.
The information in question
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific file types or data categories has been released. Companies of this kind commonly store client project documentation, contact information, pricing schedules, and correspondence; however, the exact data taken in this case remains unconfirmed.
The real-world impact
Exposed internal files could contain commercially sensitive material or personal information belonging to clients and partners. Individuals whose details appear in such records may face increased risk of targeted phishing or misuse of contact data. For the organisation, the incident may affect ongoing project timelines and relationships with clients who require assurances about data handling.
What to do if you're exposed
Individuals who have worked with Zabun or similar firms should monitor their email accounts for unusual activity and consider enabling multi-factor authentication on any linked services. They can also run a free exposure scan of their email address against known breach data to check for prior appearances of their information. Organisations should review access logs and update credentials for any systems that may have been reachable during the period of the incident.

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.
