PT Pertamina Gas Listed by kelvinsecurity Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The PT Pertamina Gas Listed by kelvinsecurity Ransomware Group (reported April 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
PT Pertamina Gas was listed on the kelvinsecurity ransomware leak site on April 22, 2022. The group claims to have stolen internal data during a ransomware attack and to have exfiltrated internal files. No further details on the timing of the intrusion, the volume of data, the method of access, or whether files were subsequently published have been made public.
Who is kelvinsecurity?
Kelvinsecurity is a ransomware operator that maintains a public leak site to list victims and, in some cases, to post samples of stolen data when ransom demands are not met. Groups of this type typically gain initial access through phishing, compromised remote-access services, or supply-chain weaknesses, then move laterally to locate and copy files before deploying encryption. Public records show the group has targeted organisations across multiple countries and industries in prior campaigns, though each listing on its site remains an unverified claim until independently confirmed.
About PT Pertamina Gas
PT Pertamina Gas is an Indonesian state-linked company engaged in natural-gas processing, transmission, and distribution. Organisations in this sector routinely hold operational records, contractual documents, technical specifications for pipelines and facilities, and employee or partner contact information. A breach at such an entity can intersect with both commercial confidentiality and the continuity of critical energy infrastructure.
What was likely exposed
The available information states only that internal files were exfiltrated. The precise categories of data, file counts, or time periods covered have not been disclosed. Companies of this type commonly store engineering documents, financial and procurement records, regulatory filings, and internal communications; however, whether any of these categories were actually taken in this case remains unconfirmed.
Why it matters
Exposure of internal operational or commercial files can create downstream risks for business partners, regulators, and employees whose information appears in those records. For the organisation, the incident may prompt reviews of access controls, logging practices, and incident-response procedures. Because the exact scope is unknown, the practical consequences for any individual or entity 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.
