Breach Intelligence Summary
Entity: Avantic Medical Lab · Actor: Everest · Sources: 2 references
Attack: Ransomware / Extortion
Profile: Healthcare provider · Diagnostic testing services · Medical laboratory network · USA
Timeline: Breach (2025-06-10) · Indexed (Sep 25, 2025) · Year (2025)
Exposure: 29K records · 10 fields: Date of Birth, Financial Account, Full Name, Government ID, Health Insurance, Lab Results, Medical Diagnosis, Phone Number, Physical Address, Social Security Number
Status: Confirmed
Executive Summary
On June 10, 2025, the Everest ransomware group added Avantic Medical Lab to its dark-web leak site, and by July 3-4, 2025 published roughly 31-33 GB of internal files (records spanning 2018-2023). The exposed archives reportedly included patient names, addresses, phone numbers, dates of birth, Social Security numbers and other government IDs, laboratory results, diagnoses and physician notes, health insurance and billing records, and payment card or check images in some cases. Everest did not disclose its intrusion method; researchers suspect stolen VPN/RDP credentials. As of the latest reporting, Avantic had not publicly confirmed the incident or filed with HHS; the record count (~29,112) reflects a DataBreach.com parse rather than an official notification. The breach is catalogued by DataBreach.com and DataBreaches.net.
ObscureIQ assessment: High risk of identity theft, medical fraud, and health-related phishing. Lab data can also reveal sensitive testing status and provider relationships.
Breach Impact
The leak exposed an unusually toxic combination of irreversible clinical data (lab results, diagnoses, physician notes) alongside Social Security numbers, government IDs, insurance records, and payment-card or check images. Unlike credit data, lab histories cannot be reset, so affected patients face lasting identity-theft, insurance-fraud, and medical-privacy harm, and the lab’s lack of formal notification left patients to learn of exposure through leaks and media.
