— from Qilin’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.

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 Sai Mai Hospital was listed on the qilin ransomware leak site on November 6, 2025. The group states it exfiltrated internal data during a ransomware attack. Exact victim counts and the full scope of stolen information remain unclear, as is common in the early stages of these incidents. The hospital has not yet issued a detailed public statement confirming the breach or specifying which systems were affected.

Available reporting describes the exposed material as internal files. Ransomware groups routinely harvest patient records, employee details, financial documents, and operational databases in healthcare attacks because this information carries both monetary and leverage value.

Why This Matters for You and Your Family

When a hospital suffers a breach, the people whose records are stored there face direct risk. If you or any member of your family has ever received treatment at Sai Mai Hospital, your personal health information, contact details, national ID numbers, or insurance data may now sit in the hands of criminals. Health records are especially damaging when leaked because they can reveal diagnoses, treatments, medications, and family medical history that you never intended to share publicly.

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.
