Clerk's notes

Onset Financial, Inc., a company specializing in commercial equipment leasing and financing, reported a cybersecurity incident to the Montana Attorney General on December 12, 2025. This breach affects the sensitive personal and financial data of individuals, stemming from an incident that occurred on May 2, 2025. The company's operations involve handling a vast array of confidential information, which was compromised as a result of this security event.

The compromised data categories reported include Full Name, Social Security Number, Date of Birth, Financial Account Number, Routing Number, Tax Return Information, Credit Score Information, and Mailing Address. The exposure of such a comprehensive set of identifiers creates a substantial risk of identity theft, financial fraud, and unauthorized account access for those affected. Given the nature of this information, individuals should remain vigilant against potential misuse.

As a financial institution, Onset Financial, Inc. is subject to strict regulatory requirements, such as the Gramm-Leach-Bliley Act, which mandate the protection of non-public personal information. The occurrence of a data breach involving such sensitive data suggests potential deficiencies in the administrative, technical, and physical safeguards implemented to protect customer information. An ongoing investigation is monitoring the breach.
