geselektrik.com.tr Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 25, 2025, the ransomware group lockbit5 listed geselektrik.com.tr on its leak site, stating that internal files had been exfiltrated from GES Genel Elektrik Sistemleri Yapım ve Mühendislik A.Ş. No confirmation of the listing or details on the volume of data, the method of access, or any ransom demand have been made public. The number of individuals potentially affected remains unknown. This incident reflects the continued targeting of engineering and infrastructure contractors by ransomware operators that combine encryption with data theft to pressure victims.

Inside the incident

The only confirmed public information is the listing itself and the group’s assertion that internal files were taken during a ransomware operation. No date of the intrusion, duration of access, or description of the files has been disclosed. The organization has not issued a statement confirming or denying the claims, and no independent verification of the data’s authenticity or scope has appeared in public reporting.

Inside lockbit5

LockBit operates as a ransomware-as-a-service group, supplying encryption tools to affiliates who conduct intrusions in exchange for a share of proceeds. The group has historically used double-extortion tactics, encrypting systems and threatening to publish stolen data if a ransom is not paid. Its leak sites function as a public catalogue of claimed victims, though the accuracy of individual listings is not independently verified in every case. LockBit has appeared in multiple law-enforcement actions and has adapted its infrastructure after disruptions.

Who is geselektrik.com.tr?

GES Genel Elektrik Sistemleri Yapım ve Mühendislik A.Ş. provides turnkey electrical installation and engineering services. Organizations in this sector routinely manage project documentation, client specifications, subcontractor records, and internal operational data. Such information can include technical drawings, contractual terms, and contact details for personnel and partners. A compromise at a firm handling electrical systems for commercial or public projects can therefore touch both corporate records and downstream parties that rely on the contractor’s work.

What was likely exposed

The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types, databases, or specific categories of personal or technical information has been released. Companies of this kind commonly store employee records, client correspondence, project schedules, and engineering documentation. The precise contents of any exfiltrated material remain unconfirmed.

What's at stake

For individuals whose information appears in the files, the main concerns are misuse of contact details or credentials and the possibility that project-related data could be used for further targeting. For the organization, the incident adds operational disruption, potential contractual complications with clients, and the cost of investigation and remediation. Because the scale of exposure is unknown, the extent of these consequences cannot yet be quantified.

Were you affected?

Individuals can begin by monitoring their email accounts and financial statements for unusual activity. Changing passwords for any services associated with the organization and enabling multi-factor authentication where available are standard first steps. Readers may also run a free exposure scan of their email address against known breach data to determine whether their information has appeared in previously published datasets.
