Donjon Listed by akira Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On 5 March 2026 the Akira ransomware group listed Donjon on its leak site, asserting that internal files had been taken from the engineering company. The number of individuals affected is not known, and no independent confirmation of the claimed data has been published. Ransomware groups continue to publish stolen corporate material as a pressure tactic. Incidents of this kind affect organisations that hold technical drawings, contracts and employee records, adding to the steady flow of such claims in the current threat environment.

Inside the incident

The incident was reported on 5 March 2026. The Akira group stated it would upload 58 GB of corporate data and described the material as including employee personal documents, HR files, drawings and specifications, projects, contracts and agreements, internal confidential files, client documents and NDAs. No further information on the date or method of access has been released.

The group behind it: akira

Akira is a ransomware operation that emerged in 2023 and has conducted intrusions against organisations in multiple sectors. Its documented pattern involves deploying ransomware, copying data, and then posting descriptions of the material on a leak site to encourage payment. The group has used this approach repeatedly in prior incidents.

In the present case the group claims responsibility for the Donjon listing. No separate verification of the data volume or contents has been made public.

Who is Donjon?

Donjon Pte Ltd was established in 2003 and operates in the mechanical and electrical engineering sector. Its services include electrical engineering, renewable energy projects, generator supply and maintenance, annual shutdown support, integrated building services, and air-conditioning and mechanical ventilation systems.

Firms of this type routinely store project documentation, client agreements, technical specifications and internal operational records as part of their normal business activities.

What was likely exposed

The Akira group claims the material consists of 58 GB of files that include employee personal documents, HR files, drawings and specifications, projects, contracts and agreements, internal confidential files, client documents and NDAs. The listing describes these categories but does not provide an itemised inventory.

The exact contents of any exfiltrated data remain unconfirmed. Organisations in this sector commonly hold technical records and contractual material, yet the specific files involved in this incident have not been independently verified.

The real-world impact

Release of employee personal documents and HR files can increase the chance of identity-related fraud or targeted scams for the individuals named in those records. Publication of contracts, client documents and project specifications may affect commercial confidentiality and relationships with clients or partners.

For the organisation the incident creates additional work in assessing the scope of access, responding to any regulatory requirements and addressing possible contractual consequences. The long-term effects depend on whether and how the claimed data is actually published.

Were you affected?

The number of people whose information may be involved is not known. Individuals who have been employed by or conducted business with Donjon should monitor their accounts for unusual activity and enable multi-factor authentication on services that support it. Checking credit reports and placing a credit freeze, where available, are standard precautionary measures.
