Mountain West Data Breach Impacts Extensive Client Info

Mountain West Insurance & Financial Services recently experienced a data breach that has impacted both current and former clients. On March 17, 2025, the insurance company discovered that a threat actor had gained unauthorized access to multiple internal employee email accounts. On Aug. 15, 2025, an investigation revealed that both personally identifiable information (PII) and protected health information (PHI) may have been accessed during the cyberattack.

Exposed information included names, Social Security numbers, dates of birth, driver license numbers, financial account numbers, financial account access information, payment card numbers, payment card access information, passport numbers, electronic signatures, medical information and health insurance information. This combination of data puts impacted individuals at risk for identity theft, financial fraud and medical identity misuse.

While the company has not disclosed the exact number of individuals affected, the wide range of information involved and the nature of client information kept on file suggest the impact could be widespread. Mountain West published a notice of data security incident on its website.
