Investigation notes

Millstone Medical Outsourcing LLC, a specialized logistics partner for the medical device industry, confirmed a data security incident to the Indiana Attorney General on September 18, 2026.

The compromised data categories reported include Full Name, Social Security Number, Date of Birth, Mailing Address, Wage and Compensation Information, Driver's License Number, Financial Account Details, and Internal Employee Identification Numbers. The exposure of such a comprehensive set of personal identifiers and financial details creates substantial, long-term risks for identity theft, financial fraud, and other harms.

As an organization entrusted with sensitive data, Millstone Medical Outsourcing LLC was bound by state and common-law duties to implement robust security measures, including those mandated by the Indiana Data Breach Notification Act. The occurrence of this incident suggests potential shortcomings in the company's data protection protocols, raising questions about whether their safeguards met these legal obligations.
