Coalinga Regional Medical Center Listed by World Leaks Ransomware Group

If you were named in this filing, here’s what is being claimed, and what it would mean for you.

Coalinga Regional Medical Center was listed on Worldleaks's leak site. Worldleaks claims to have stolen internal data. This is the group's claim, not a confirmed finding.

Coalinga Regional Medical Center Listed by World Leaks Ransomware Group

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates that Coalinga Regional Medical Center, a non-profit healthcare facility in Coalinga, California, was hit by a ransomware operation. The attackers extracted internal files before encrypting systems or disrupting operations. No exact count of affected individuals has been released, but any patient records, employee documents, or vendor files contained in those internal systems are now at risk. The leak site listing states the data was exfiltrated and is being used as leverage.

Worldleaks posted the Coalinga files on its onion site, following the group’s standard practice of publishing proof of compromise when victims do not pay. Available reporting describes the exposed material as internal files, though the precise volume and specific data types remain unconfirmed in initial disclosures.

Why This Matters for You and Your Family

If you or anyone in your family has ever received care at Coalinga Regional Medical Center, your personal information may have been inside the stolen files. Medical records often contain names, dates of birth, Social Security numbers, addresses, insurance details, and clinical information. Once that data leaves a hospital’s control, it can surface in identity theft schemes, insurance fraud, or phishing campaigns tailored to look like legitimate medical communications.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
