San Bernardino County, which operates Arrowhead Regional Medical Center (ARMC), officially reported a data security incident on September 28, 2026. This breach, which occurred on August 28, 2026, involved the exposure of sensitive patient information held by the healthcare provider. The full extent and mechanics of the intrusion are currently under ongoing investigation.
The compromised information includes highly personal details such as Full Name, Date of Birth, Social Security Number, Medical Record Number, Health Insurance ID Number, Diagnosis and Treatment Information, Prescription Information, and Provider and Treatment Dates. This combination of data can pose significant risks to those affected.
Unlike financial data that can be easily replaced, this type of exposed medical and personal identification information carries long-term risks. It could be used for medical identity theft, where an unauthorized person uses your identity to obtain healthcare services, potentially leading to incorrect medical records and impacts on your care. The exposure of Social Security Numbers, combined with other identifiers, also raises the risk of financial fraud and other identity-related crimes.
