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 sinobi listed Pivotal Healthcare on its dark-web leak page, claiming to have stolen company files during a ransomware incident. The company, which operates in the Hospitals & Physicians Clinics sector, employs between 10 and 19 people and generates annual revenue estimated between $500,000 and $1 million. No exact count of affected individuals has been released, and the precise volume or sensitivity of the exfiltrated files remains unclear from available reporting. The listing appeared on the sinobi leak site, accessible via the .onion address tracked by ransomware.live.

Why This Matters for You and Your Family

When a healthcare provider’s internal files are stolen, the information inside can easily include patient names, dates of birth, Social Security numbers, medical records, insurance details, and contact information for you or your family members. Even a small clinic handles data for hundreds or thousands of local patients. Once that material leaves the company’s control, it can surface on criminal forums where identity thieves, fraudsters, and extortionists trade or sell it. Medical data is especially damaging because it is difficult to change and can be used for insurance fraud, prescription scams, or blackmail. If you or your children have ever been treated at a facility connected to Pivotal Healthcare, your personal information may now be in unauthorized hands.

The Doxxing and Identity-Chain Risks

Stolen healthcare files rarely stay isolated. Attackers routinely cross-reference exposed emails, phone numbers, and patient addresses with usernames found in other breaches. This creates an identity chain that links your real name to gaming accounts, social-media handles, family members’ profiles, and even your children’s online activities. A single credential leak from a clinic database can cascade into account takeovers across unrelated services. Gaming accounts are particularly vulnerable because children often reuse simple passwords or email addresses tied to family medical records. Public reporting describes these chains leading to doxxing, harassment, and financial fraud that can affect an entire household.

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.
