cryopur.com Listed by incransom Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Cryopur.com has been listed by the Incransom ransomware group, which claims to have exfiltrated internal files from the organisation. The incident was disclosed on 24 November 2025, with the number of affected individuals and the exact date of the intrusion not yet established; anyone who has shared data with cryopur.com should review their accounts and monitor for unusual activity.
CryoPur, a French company working in cryogenic technology for biogas processing, was listed on November 24, 2025, by the ransomware group incransom. The listing states that internal files were taken during a ransomware operation. The number of individuals whose information may be involved remains unknown, and no further details on the volume or specific contents of the data have been made public.
The incident matters because CryoPur handles technical and operational records tied to energy infrastructure projects. Even without confirmed personal data, exposure of internal documents can create downstream risks for partner organisations, facility operators, and the supply chain that relies on those systems.
Breaking down the breach
The only confirmed public information is the November 24, 2025 listing by incransom. The group asserts that files were exfiltrated in a ransomware attack. No independent confirmation of the data volume, encryption status, or restoration outcome has been released. The date the intrusion began, the duration of access, and any ransom demand or payment remain undisclosed.
Inside incransom
Incransom is a ransomware operation that maintains a leak site to publish data from claimed victims. Groups of this type typically gain initial access through phishing, exposed remote services, or compromised credentials, then move laterally to locate and copy files before deploying encryption. The listing of CryoPur follows the pattern these actors use to pressure organisations, though the accuracy of any specific claim on the site is not independently verified.
About cryopur.com
CryoPur, based in Massy, France, develops technology that purifies and liquefies biogas into bio-LNG and high-purity liquid carbon dioxide. Founded in 2015, the company was later acquired by La Française de l’Énergie, which holds 94 percent ownership. Its systems are deployed at agricultural, industrial, wastewater, and landfill sites. Organisations in this sector maintain engineering specifications, process data, client contracts, and regulatory compliance records that support critical energy infrastructure.
The information in question
The listing refers only to “internal files.” No inventory of file types, no indication of customer records, employee data, or third-party information, and no confirmation of personal identifiers have been published. Companies of this kind routinely store technical drawings, operational logs, supplier agreements, and safety documentation; whether any of these categories appear in the exfiltrated material is unconfirmed.
The real-world impact
Exposure of internal engineering and operational files can reveal details about facility configurations and processes that are normally kept restricted. For partner sites and regulators, this may require additional review of access controls and incident response procedures. For individuals, the absence of confirmed personal data limits immediate conclusions, yet any future release of documents containing names, contact details, or contractual information would expand the potential consequences.
If your data was in this claimed breach

Publicly posted by incransom — 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.
