PT Brantas Abipraya Listed by everest Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
PT Brantas Abipraya was listed on March 31, 2026 by the everest ransomware group, which claims to have exfiltrated internal files from the company. Individuals whose data may have been exposed should check for any notifications from the organisation and take appropriate security precautions.
What happened
The incident is known only through the group’s public listing. Everest claims to have obtained internal files from the company. The date of the intrusion, the method of access, and the volume of data involved have not been disclosed. No statement from PT Brantas Abipraya confirming or denying the claims has been reported.
The group behind it: everest
Everest is a ransomware operation that follows a double-extortion model: it encrypts systems and also removes data before demanding payment. When victims refuse or negotiations fail, the group publishes file listings on its site. The group has previously claimed activity against organisations in multiple countries and sectors. Its listing of PT Brantas Abipraya is an unverified claim made by the group itself.
About PT Brantas Abipraya
PT Brantas Abipraya is a state-owned Indonesian construction company established in 1980. Its original focus was water infrastructure such as dams, irrigation systems and hydroelectric plants. The company has since expanded into airports, roads, bridges, buildings and other civil works. As a state-linked entity it holds records relating to public projects, contractors, employees and regulatory compliance.
The information in question
The only detail released is that internal files were allegedly exfiltrated. The precise categories of data are not confirmed. Organisations of this type routinely maintain employee records, supplier contracts, project documentation and financial information, but whether any of these categories were taken remains unverified.
The real-world impact
Until the contents of the files are known, the practical effects on individuals cannot be quantified. Potential concerns include exposure of personal identifiers or project-related details that could be misused for fraud or targeted scams. For the company, the incident adds to operational and reputational pressures typical of ransomware disclosures involving state-owned infrastructure entities.

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.
