yuagam Listed by Qilin Ransomware Group

If you are a customer of yuagam, here’s what is being claimed, and what it would mean for you.

yuagam was listed on Qilin's leak site. Qilin claims to have stolen internal data. This is the group's claim, not a confirmed finding.

On February 25, 2025, the Qilin ransomware group listed Yeditepe University Healthcare Institutions on its leak site and began publishing what it claims are the Turkish hospital group's internal files. The healthcare organization, founded in 2005 and operating multiple hospitals in Istanbul, has not yet confirmed the breach or disclosed how many patients and staff may be affected. Public reporting indicates that patient records, employee data, and other sensitive internal documents appear to be among the exfiltrated material.

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

Available reporting describes the incident as a classic ransomware attack in which the threat actors gained access, exfiltrated data, and then encrypted systems. The Qilin group posted the Yeditepe University Healthcare Institutions entry on its dark-web leak portal on February 25, 2025. While the exact number of records exposed remains unknown, the data types referenced include internal files that would typically contain names, medical histories, national identification numbers, contact details, and financial information related to patient care and hospital operations. The group has set a deadline for publication of the remaining archive, a common pressure tactic.

Why This Matters for You and Your Family

When a hospital or healthcare provider is breached, the information stolen is deeply personal. Medical records can reveal diagnoses, treatments, medications, and family health history that you expect to remain private. If your or your child's records were among those taken, criminals can use them for identity theft, insurance fraud, or targeted scams that feel personal because the attackers know details only your doctor should know. Patient data from hospital systems tends to remain valuable on the criminal market for years, meaning the risk does not end when the headlines fade.

The Doxxing and Identity-Chain Implications

Medical breaches rarely stop at the initial leak. Criminals frequently link exposed email addresses, phone numbers, and patient IDs to usernames on social media, gaming platforms, and other services. This creates an identity chain that can lead to doxxing, account takeovers, and harassment. Credential leaks like this one often cascade into gaming accounts belonging to you or your children, especially when the same password or email was reused. Once attackers control a gaming profile tied to a real name and address, they can escalate to full doxxing by publishing home addresses, family member names, and photos. Identity-chain mapping has become one of the fastest ways small leaks turn into long-term privacy nightmares for ordinary families.

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.
