Aflac Incorporated data breach

Clerk's notes

Aflac Incorporated, a prominent supplemental insurance provider, filed notice with the Montana Attorney General on December 19, 2025, regarding a data breach that occurred on June 12, 2025. This incident, currently under monitoring, involved the unauthorized exposure of highly confidential information belonging to policyholders.

The compromised data types identified include Full Name, Social Security Number, Date of Birth, Policy Number, Financial Account Number, Routing Number, Claims and Medical Information, and Address and Contact Information. The exposure of such a comprehensive array of personal and financial identifiers places affected individuals at heightened risk for various forms of identity theft and financial fraud.

Specifically, the presence of Social Security Number and Date of Birth, alongside financial and medical records, provides malicious actors with critical components for establishing fraudulent accounts, misusing insurance benefits, or filing false claims. This extensive data exposure creates long-term vulnerabilities for those impacted, potentially affecting credit, financial stability, and even medical history.

Given the nature of the data involved and Aflac's role in the insurance and financial sectors, the company is subject to strict data security regulations, including the Gramm-Leach-Bliley Act (GLBA) and state insurance laws. These mandates require robust safeguards for consumer data. The occurrence of this breach raises questions regarding the sufficiency of Aflac's security measures in preventing unauthorized access to sensitive policyholder information.
