The Cabinet Remy Le Bonnois / Data on sale Listed by everest Ransomware Group (reported November 11, 2021) 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.
On November 11, 2021, the ransomware group Everest listed Cabinet Remy Le Bonnois / Data on sale on its data-leak site. The listing states that internal files were taken during a ransomware incident. No figure for the number of people affected has been published, and the organization has not issued a public statement confirming or denying the claims.
What happened
The only confirmed public record is the appearance of Cabinet Remy Le Bonnois / Data on sale on Everest’s leak site on 11 November 2021. The group asserts that it exfiltrated internal files. No additional details—such as the date of the intrusion, the volume of data, or whether encryption was also deployed—have been disclosed by either the group or the organization.
Who is everest?
Everest is a ransomware operation that follows a double-extortion model: it encrypts systems and separately threatens to publish stolen files if a ransom is not paid. The group maintains a site where it lists victims and posts samples of claimed data. Its listings are presented by the group itself and remain unverified until corroborated by the affected organization or independent investigation.
Cabinet Remy Le Bonnois / Data on sale and its sector
Cabinet Remy Le Bonnois appears to be a professional-services firm, most likely operating in a legal or advisory capacity. Organizations of this type routinely store client correspondence, contracts, financial records, and identification documents. A breach at such an entity can expose information belonging to many individuals beyond the firm’s own employees.
What data was at risk
The listing refers only to “internal files.” The precise categories of data have not been published. Professional-services firms commonly hold personal identifiers, client financial details, and privileged communications, but it is not confirmed whether any of these were among the files taken in this case.
What's at stake
Individuals whose information appears in the exfiltrated files face the possibility of their data being used for fraud or further targeting. The organization itself may encounter regulatory scrutiny and loss of client trust. Because the exact contents remain undisclosed, the scale of these risks cannot yet be quantified.

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.
