cryopur.com Listed by incransom Ransomware Group

On November 24, 2025, French cryogenic technology firm CryoPur appeared on the leak site of the incransom ransomware group, with internal files exfiltrated during a ransomware attack.

What's Publicly Reported from Reporting

Public reporting indicates that CryoPur, headquartered in Massy, Île-de-France, specializes in advanced systems that convert raw biogas into high-purity bio-LNG and liquid CO₂. The company was founded in 2015 and holds patents for its purification and liquefaction processes, which serve agricultural, industrial, wastewater, and landfill facilities. It is now 94 percent owned by La Française de l’Énergie (FDE) following an acquisition.

Available reporting describes the incident as a ransomware attack in which internal files were allegedly exfiltrated. The number of individuals whose personal data may have been exposed remains unknown. No specific deadline for payment or further data publication has been confirmed in the initial disclosure.

Why This Matters for You and Your Family

When a company like CryoPur suffers a breach, the information stolen often includes documents that contain names, addresses, contact details, employee records, or partner information. If you or anyone in your family has ever worked with CryoPur, supplied services to its facilities, or been a customer at one of the biogas plants it supports, your details could be among the leaked files.

Credential leaks like this one frequently cascade into account takeovers elsewhere. A single email address or reused password taken from business records can give attackers the key to your personal banking, email, or shopping accounts. For families this risk multiplies: children’s school forms, medical consents, or family-shared logins can all surface in the same dataset.

The Doxxing and Identity-Chain Implications

Ransomware operators rarely stop at dumping raw files. Once internal documents are public, opportunistic criminals scrape them for personal identifiers and begin building identity chains — linking an email to a phone number, a home address, social-media handles, and eventually family members. These chains fuel doxxing, targeted phishing, and identity theft that can affect every household member.

Children’s gaming accounts are especially vulnerable in these chains. A parent’s work email reused as a recovery address for a child’s Roblox, Fortnite, or Discord account creates a direct path from corporate breach to personal gaming compromise. What begins as a business ransomware incident can end with a teenager’s private chats or in-game purchases exposed.

Incransom Group’s Known Track Record

Public reporting attributes the attack to the incransom ransomware group. The group emerged in recent years and follows a double-extortion playbook: it first encrypts victim systems, then exfiltrates data before threatening to publish it unless a ransom is paid. Notable prior victims have included organizations across Europe and North America, though exact details vary by incident. Typical initial access involves phishing or exploited remote desktop services, followed by rapid data theft and publication on their leak site when negotiations fail.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by specialists.
• Rotate any password you used at CryoPur or related business services anywhere it has been reused, and switch on 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your information is caught in hours, not months.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that often chain back to the same addresses and recovery emails.
• Let remediation specialists handle takedown requests across data brokers and leak sites for you while you focus on securing your own accounts.
