Lumio Dental Data Breach Exposes Sensitive Personal and Medical Information
On February 5, 2026, the Nitrogen ransomware group claimed responsibility for a data breach targeting Lumio Dental, a dental partnership organization based in Tulsa, Oklahoma. The incident compromised sensitive information belonging to approximately 500 individuals across the U.S., including passports, driver’s licenses, and medical records.
Lumio Dental disclosed the breach, though it remains unclear whether affected individuals have been notified directly or offered credit monitoring or identity protection services. The exposed data could be exploited for financial fraud, identity theft, or medical identity theft, prompting authorities to advise impacted individuals to take precautionary steps.
Those affected are encouraged to monitor credit reports via AnnualCreditReport.com, place fraud alerts or credit freezes with major credit bureaus (Equifax, Experian, TransUnion), and review health insurance statements for suspicious activity. If signs of misuse are detected, individuals can report incidents to the Federal Trade Commission (FTC) at IdentityTheft.gov or contact the U.S. Department of State if passport details were compromised.
Lumio Dental has provided a contact number (800-614-0263) for further inquiries. The breach was reported to the U.S. Department of Health and Human Services, though additional details about the incident remain limited.
