Balance Diagnostics, a medical imaging provider based in Cedarhurst, New York, was attacked on May 6, 2025 by the Everest ransomware operation. Initial samples of stolen data appeared on Everest's dark-web leak page immediately after the incident. The full cache, containing approximately 31,000 records, was released publicly on June 18, 2025 after ransom demands went unmet.\n\nThe breach affected approximately 26,000 individuals based on the records indexed by breach-tracking services. Compromised fields included names, email addresses, phone numbers, home addresses, and Social Security numbers. As a medical imaging provider, the underlying records exfiltrated by the attackers also include diagnostic imaging studies, referring-physician details, billing records, and insurance information typical of an outpatient radiology operation.\n\nFor affected patients, the practical risk profile combines identity-fraud exposure with medical-imaging-specific risks. The combination of name, address, and Social Security number is a strong base for synthetic identity fraud and fraudulent credit applications. Inclusion in the dataset confirms a diagnostic-imaging relationship and likely identifies the referring physician, which can support medical-themed phishing referencing real imaging studies, results, or insurance disputes. Affected patients should freeze credit at all three U.S. bureaus, monitor health-insurance statements for unfamiliar imaging or diagnostic charges, and treat unsolicited contact referencing Balance Diagnostics, imaging studies, or referring physicians with caution.

Diagnostic and testing providers collect patient identity, contact, insurance, billing, appointment, and test-related medical records across clinical and administrative workflows.

Balance Diagnostics was attacked on May 6, 2025 by the Everest ransomware gang. Initial data samples appeared on dark-web leak pages immediately after the incident, and the full dataset of approximately 31,000 records was released on June 18, 2025 after ransom demands went unmet. The practice has not publicly disclosed extensive operational detail about the incident as of this writing. The Everest gang has been an active extortion group throughout 2024 and 2025 with multiple healthcare-sector victims. Class-action investigations by U.S. plaintiff law firms followed the dataset release in mid-2025. HHS Office for Civil Rights review obligations apply.
