Unlimited Technology Systems says hackers stole sensitive personal, medical, and health insurance information from one of its commercial data centers, affecting 3,803,750 people. The company, which provides revenue-cycle and financial technology services to healthcare providers including oncology and specialty practices, says the intrusion occurred between October 5 and October 10, 2025 and was discovered in October 2025. Exposed data includes Social Security numbers, medical record numbers, diagnoses, dates of service, policy and claims information, and scanned identity documents.
Why it matters: This is a major healthcare-sector breach with enough data exposed to enable identity theft, insurance fraud, and targeted phishing against patients. Affected people should watch for breach notices, enroll in monitoring, and be alert for scams using medical or insurance details.
