111 Listed by everest Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

People whose personal or professional information is held by organizations hit by ransomware face the possibility that internal records could surface publicly or be misused. The Everest ransomware group claims to have listed an entity identified as 111 on its leak site following an attack in which internal files were taken, with the listing reported on February 25, 2026. The number of individuals potentially affected remains unknown, and no further details on the scope or confirmation of the data release have been made public.

What happened

The incident centers on a ransomware attack against the organization listed as 111. The group claims responsibility and states that internal files were exfiltrated. The listing appeared on February 25, 2026. No information has been released on the timing of the intrusion itself, the volume of data involved, or the specific methods used beyond the general description of a ransomware operation that included file theft.

Who is everest?

Everest is a ransomware group that follows a double-extortion model. It typically encrypts systems, removes copies of data, and then posts victim names on a dedicated leak site when ransom demands are not met. The group has carried out multiple operations against organizations in various sectors and uses the public listing as leverage. In this instance the listing of 111 constitutes the group’s claim; independent confirmation of the data’s authenticity or volume has not been reported.

About 111 Listed by everest Ransomware Group

Public detail on the organization identified as 111 is limited. No sector, size, or operational description appears in available reports of the incident. Without that context it is not possible to outline the typical records such an entity would maintain.

What was likely exposed

The only data category named in connection with the incident is internal files exfiltrated during the ransomware attack. The exact contents of those files have not been disclosed. Because the organization’s sector and data holdings remain unspecified, it is not possible to state with certainty what categories of personal or operational information may be present.

The real-world impact

Internal files can contain communications, operational records, or identifiers that, if released, could be used for further targeting or fraud. Individuals connected to the organization may face increased risk of phishing or identity misuse depending on what the files contain. The organization itself may encounter operational disruption and costs associated with investigation and recovery, though the scale of these effects is not yet known.
