Adept Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Adept has been listed by the sinobi ransomware group, with internal files reported to have been exfiltrated in a ransomware attack. The incident was disclosed on November 22, 2025, but the date of the breach itself has not been established; individuals should check whether their data was involved and take appropriate protective steps.
What happened
The listing appeared on November 22, 2025. The number of people affected is not known. The only detail provided is that internal files were allegedly exfiltrated during a ransomware attack. Timing of the intrusion, volume of data, and technical method used remain undisclosed.
The group behind it: sinobi
Sinobi is a ransomware operator that commonly encrypts systems, removes copies of data, and then posts victim names on a dedicated leak site to pressure payment. The group claims responsibility for the Adept incident solely through the public listing. Its documented pattern involves targeting mid-sized organizations across multiple countries and sectors.
Who is Adept?
Adept, operating as ADEPT Projects, provides urban development and design services focused on sustainable and functional spaces. Its clients include municipalities, developers, and other organizations involved in community infrastructure. Public information notes the company's participation in projects such as Videnbyen Cortex Park.
What was likely exposed
The listing states only that internal files were exfiltrated. No inventory of file contents or data categories has been released. The exact scope of any personal or project information therefore remains unconfirmed.
Why it matters
Internal files from an urban-development firm can contain references to municipal partners, contractors, and site-specific plans. Unauthorized release of such material may create follow-on exposure for those third parties even if no personal records are involved. The organization itself faces potential disruption to project timelines and client trust.
If your data was in this claimed breach
Anyone who has corresponded with Adept or participated in its projects should watch for unusual account activity and review access to any shared documents. Running a free exposure scan of an email address against known breach repositories provides one way to check for prior appearances of that address.
- Review recent statements from banks, government portals, or project partners for unexpected changes.
- Enable multi-factor authentication on any accounts tied to the organization or its clients.
- Retain records of communications with Adept in case further details about the files become available.

Publicly posted by sinobi — unverified claim, pending independent verification
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.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
