DUKOSI.COM Listed by clop Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On February 7, 2026, the website dukosi.com appeared on a listing associated with the Clop ransomware group. The entry states that internal files were exfiltrated from Dukosi Limited during a ransomware attack. No information has been released on the number of individuals affected or the volume of data involved. The incident remains limited to this listing and the general description of exfiltrated internal files. No confirmation of the data’s contents, any ransom demand, or subsequent publication has been made public.

Inside the incident

The only confirmed detail is the appearance of dukosi.com on the group’s listing on the reported date. The entry describes the taking of internal files but provides no further technical information about how access was obtained or the duration of any intrusion. The number of people potentially affected is listed as unknown, and no timeline for the underlying events has been disclosed.

The group behind it: clop

Clop is a ransomware group that has operated for several years and maintains a public listing of claimed victims. The group typically uses double-extortion tactics, first encrypting systems and then threatening to release stolen data. Its listings are presented by the group itself and constitute claims rather than independently verified events. Prior public reporting has documented Clop’s activity against organisations in multiple sectors, though each incident requires separate confirmation.

DUKOSI.COM and its sector

Dukosi Limited is a United Kingdom technology company that develops battery management systems. Its work focuses on improving the design, deployment and ongoing management of advanced batteries used in electric vehicles, stationary energy storage and aviation applications. Companies in this sector routinely handle engineering specifications, test data and operational information related to battery performance and safety systems.

What data was at risk

The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific file types or data categories has been published. Organisations working on battery management technology commonly store proprietary design documents, test results and supplier information, but the exact material taken in this case has not been confirmed.

The real-world impact

Exposure of internal engineering and operational files can create competitive or security concerns for the company. For individuals, any personal data that may have been stored in those files could increase risks of targeted phishing or identity misuse, though the presence of such data has not been established. The organisation faces the task of assessing the scope of access and any resulting operational or regulatory obligations.

Individuals who have had contact with Dukosi Limited through employment, contracts or product use should monitor their email and financial accounts for unusual activity. Changing passwords for any associated accounts and enabling multi-factor authentication remain standard first steps.
