HEMERIA Listed by snatch Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The HEMERIA Listed by snatch Ransomware Group (reported May 22, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
What happened
The incident came to light when snatch posted HEMERIA on its data-leak platform. The group claims to have carried out a ransomware attack and to have exfiltrated internal files. No official confirmation of the breach from HEMERIA has been referenced in available records, and the exact date of the intrusion, the method of access, and the quantity of data involved are not disclosed.
Who is snatch?
Snatch is a ransomware operation that has been publicly active since at least 2019. The group typically deploys encryption on victim systems and maintains a leak site where it lists organizations from which it claims to have stolen data. Its listings serve as a pressure tactic, with the group stating that stolen files will be released if a ransom demand is not met. Snatch has appeared in multiple public reports covering ransomware activity against companies in various sectors, though each listing remains an unverified claim by the group itself.
About HEMERIA
HEMERIA designs and manufactures high-dependability equipment and systems for the space industry and for France’s nuclear deterrence force. Organizations in this sector routinely handle technical specifications, engineering data, supplier information, and project documentation tied to sensitive national programs. A listing by a ransomware group therefore draws attention because of the nature of the work rather than because of any confirmed scale of data exposure.
What was likely exposed
The only detail provided is that internal files were allegedly exfiltrated. No specific categories of data, such as personal records or particular file types, are named in the available facts. Organizations of this kind commonly store engineering documents, contract materials, and operational records, yet the precise contents of the exfiltrated material remain unconfirmed.
Why it matters
Even without a disclosed count of affected individuals, the exposure of internal files from a company working on space and nuclear-deterrence systems raises the possibility that technical or programmatic information could circulate beyond its intended recipients. For the organization, the incident adds the operational burden of investigating the intrusion, restoring systems, and managing any subsequent disclosures. For any individuals whose data may have been among the files, the main practical consequence is the potential for that information to appear in future misuse, though the likelihood cannot be assessed from the facts currently available.
If your data was in this claimed breach
Begin by changing passwords for any accounts that may be linked to the organization and enable multi-factor authentication where available. Monitor bank and government-service accounts for unusual activity and consider placing fraud alerts with credit agencies if personal identifiers were involved.

Publicly posted by snatch — 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.
