On April 1, 2026, the ransomware group Everest listed Nissan on its leak site, stating that internal files had been exfiltrated during a ransomware attack. The number of individuals affected is not known, and no further details about the scope or timing of the incident have been confirmed publicly.
Inside the incident
The only confirmed information is the listing itself and the claim that internal files were taken. No data volume, specific file categories, or confirmation of encryption has been disclosed. Nissan has not issued a public statement on the matter, and independent verification of the exfiltration remains unavailable.
Who is everest?
Everest is a ransomware group that lists victim organizations on a dedicated leak site when ransom demands are not met. The group’s practice is to claim data theft and threaten publication of stolen material. Its listing of Nissan constitutes an unverified claim by the group; no independent confirmation of the incident has been reported.

It produces passenger vehicles, commercial vehicles, and participates in the Renault–Nissan–Mitsubishi Alliance. Automotive manufacturers routinely hold engineering data, supply-chain records, employee information, and customer records as part of normal operations.
What was likely exposed
The listing refers only to “internal files exfiltrated in ransomware attack.” The precise contents of those files have not been disclosed. Organizations of this type commonly store technical specifications, business correspondence, and personal data of employees or customers, but whether any such categories were involved remains unconfirmed.
Why it matters
Exposure of internal files can create operational and competitive risks for the organization and may affect individuals whose information appears in those files. Without Reported Details on the data types or volume, the exact consequences for any specific person cannot be assessed at this time.

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.
