Clean Air Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Clean Air has been listed by the sinobi ransomware group, with internal files reported to have been exfiltrated in an attack disclosed on December 09, 2025. Individuals are advised to check whether their information was included in the incident and to monitor their accounts for any unusual activity.
Inside the incident
Public information on the event is limited to the group’s listing. The date the data was taken, the method of initial access, and the volume of material removed are not disclosed. No confirmation from Clean Air or independent verification of the claims has been reported.
The group behind it: sinobi
Sinobi is a ransomware operator that has appeared on leak sites in recent years. The group typically claims to have exfiltrated data before deploying encryption and then lists the victim on its site to pressure payment. Its listings are presented as claims by the group; independent confirmation of the underlying incidents varies by case.
Clean Air and its sector
Clean Air operates in the laboratory safety equipment sector. Organisations of this type design, test, and manufacture equipment such as biological safety cabinets, fume hoods, and isolators used in biotechnology, pharmaceutical, and life-science laboratories. They routinely handle technical specifications, client project details, and compliance documentation.
What data was at risk
The listing refers only to “internal files exfiltrated in ransomware attack.” The precise categories of information contained in those files have not been published. Organisations in this sector commonly store engineering drawings, client correspondence, testing records, and regulatory materials, but the exact contents remain unconfirmed.
The real-world impact
Exposure of internal files can reveal proprietary designs or client project information. For individuals whose details appear in such records, the main risks are targeted phishing or misuse of contact data. The organisation may face operational disruption and costs associated with investigation and remediation.
What to do if you're exposed
Monitor accounts for unusual activity and change passwords for any services linked to the organisation. Enable multi-factor authentication where available. Individuals can run a free exposure scan of their email address to check whether their information appears in known breach data.
- Review bank and credit statements for unauthorised transactions.
- Place fraud alerts with credit bureaus if personal identifiers were involved.
- Keep software and devices updated to reduce future intrusion risks.

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.
