United Sleep Diagnostics Listed by Medusa Ransomware Group

On November 1, 2024, United Sleep Diagnostics appeared on the leak site operated by the Medusa ransomware group. The New York-based provider of sleep-disorder monitoring services is the latest victim in a ransomware campaign that exfiltrated 1.20 TB of internal files. The company has not yet issued a public breach notification, so the precise number of affected individuals remains unknown.

Details from the Leak-Site Listing

The Medusa leak page states that United Sleep Diagnostics suffered a ransomware attack in which attackers gained access to corporate systems and exfiltrated internal files before encryption. The listing claims 1.20 TB of data was taken and warns that the files will be published if the company does not meet the group’s demands. The disclosure does not specify the exact types of records involved, though internal files from a medical diagnostics provider typically include patient information, insurance details, employee records, and operational documents. No sample data has been released publicly at the time of writing.

Why This Matters for You and Your Family

If you or a family member have ever undergone a sleep study, used a CPAP machine, or received care through United Sleep Diagnostics, your protected health information may now sit in an attacker’s archive. Health data is especially sensitive because it can reveal chronic conditions, prescription histories, and home addresses. Even when the exact number of records is unknown, the exposure of internal files from a specialized clinic creates real risk for patients whose names, dates of birth, Social Security numbers, or insurance identifiers were stored in those systems. Ransomware operators rarely limit themselves to corporate spreadsheets; patient intake forms and billing databases are frequent targets.

Doxxing and Identity-Chain Risks

Stolen internal files rarely stay isolated. Attackers or subsequent buyers can combine leaked medical records with other breach data to build detailed identity profiles. A sleep-clinic spreadsheet that links a name to a home address, phone number, and email can be chained with credential leaks from other services. This is exactly how doxxing campaigns escalate: one record exposes an email, that email unlocks a password reuse on a retail site, and the retail account yields payment details or additional personal documents. Children’s information is not immune; many families list dependents on insurance forms, and gaming accounts tied to the same email or phone number become easy follow-on targets for account takeover and further harassment.

Medusa Ransomware Group Track Record

Public reporting attributes Medusa’s first major campaigns to late 2021. The group operates a double-extortion model: it encrypts victim networks and simultaneously threatens to publish stolen data unless a ransom is paid. Notable prior victims include municipal governments, manufacturing firms, and healthcare providers. Medusa typically gains initial access through compromised remote desktop credentials or exploited vulnerabilities in internet-facing applications, then moves laterally to locate and exfiltrate sensitive folders before triggering encryption. Their leak site functions as both a shaming platform and a countdown clock, with deadlines that can range from days to several weeks. The group continues to evolve its tooling and has maintained steady activity into 2024.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity so you can see exactly where this claimed breach connects to the rest of your digital footprint.
• Rotate any password you ever used at United Sleep Diagnostics or related medical portals and enable 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces within hours instead of months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that often chain back to the same contact details.
• Let remediation specialists handle data-broker takedown requests and opt-out processes that would otherwise consume weeks of your time.

The Medusa listing is a reminder that healthcare providers remain high-value targets and that patient data can surface on criminal marketplaces long before any official notice arrives. Starting with a clear map of your exposed information gives you the best chance to limit damage before identity thieves or harassers connect the dots. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists, with household coverage that includes children’s gaming accounts vulnerable to credential-stuffing attacks.
