What happened
The incident was reported on 01 May 2026. Public information states only that gursoygrup.com.tr was listed by the lockbit5 group and that internal files were exfiltrated during a ransomware attack. No figure for the number of people affected has been released, and no further technical details about the intrusion method or timeline have been disclosed.
Who is lockbit5?
LockBit is a ransomware-as-a-service operation that has conducted numerous campaigns against organisations in multiple countries. Its typical pattern involves encrypting systems and copying data, then posting the names of targeted entities on a leak site to increase pressure during negotiations. The group’s listing of gursoygrup.com.tr constitutes a claim by the operators; independent confirmation of the data’s authenticity or volume has not been provided.
gursoygrup.com.tr and its sector
Gürsoy Grup is described as a Turkish company with more than thirty years of operation across seven sectors. Organisations of this profile commonly maintain records relating to employees, suppliers, financial transactions and project documentation. A breach at such a firm can therefore touch both corporate records and information belonging to private individuals.
What data was at risk
The only detail released is that internal files were taken. The precise categories of information contained in those files have not been published. Companies in this sector routinely hold contact details, employment records and contractual documents; whether any of these specific items were among the exfiltrated material remains unconfirmed.
What's at stake
Exposed internal files can lead to follow-on misuse of personal identifiers, business relationships or financial references. For the organisation, the event may result in operational disruption and the need to review security controls. For affected individuals, the main practical concern is the potential for targeted fraud or unwanted contact if their details appear in the stolen material.
If your data was in this claimed breach
Monitor bank and email accounts for unusual activity and consider placing fraud alerts with credit agencies where available. Use strong, unique passwords and enable multi-factor authentication on important services. Readers can run a free exposure scan of their email address against known breach data to check for prior appearances of their information.

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.
