AiHealth Listed by The Gentlemen Ransomware Group

The company, which helps customers locate doctors, book appointments, order medication, and arrange home nursing care, is claimed to have had internal files exfiltrated following a ransomware attack.

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 thegentlemen listed AiHealth on its dark-web leak site on November 24, 2025. The data consists of internal files exfiltrated during a ransomware incident. Exact victim numbers remain unknown, and the precise contents of the files have not been independently verified by third parties. The company operates an online pharmacy network and provides tools for remote medical consultations and at-home healthcare services across Vietnam.

Why This Matters for You and Your Family

When a healthcare provider is breached, the information exposed often includes names, addresses, phone numbers, dates of birth, national identification numbers, and details of medical conditions or prescriptions. For you or your family, this can lead to targeted fraud, insurance abuse, or phishing emails that appear to come from a doctor or pharmacy you actually used. Medical data is especially sensitive because it can be used to impersonate you when dealing with insurers, government agencies, or even employers.

Credential leaks from healthcare portals frequently cascade into other accounts. If you reused the same password at AiHealth that you use for email, banking, or shopping, those accounts become immediate targets.

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.
