Aflac Incorporated, a leading supplemental insurance provider, filed a data breach notification with the Montana Attorney General on December 19, 2025. This filing reported a security incident that occurred on June 12, 2025. The nature of the breach was reported as unspecified, and the investigation status is currently noted as "monitoring."

The data categories reportedly exposed in this incident 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. This comprehensive list covers highly sensitive personal identifiers and financial details.

Exposure of such a wide range of personal data, especially Social Security Numbers and financial account information, significantly increases the risk of identity theft, various forms of fraud, and unauthorized access to personal accounts. Individuals whose Claims and Medical Information was exposed should also be alert to the potential for medical identity fraud.

To help protect against potential harm, affected individuals should carefully review their account statements, regularly monitor their credit reports for any unusual or unauthorized activity, and consider placing a fraud alert or security freeze on their credit files. It is also recommended to be cautious of any unsolicited communications that request personal information.

This information is based on public records filed with the Montana Attorney General's office, providing verified details about the reported security incident involving Aflac Incorporated.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Watch your financial accounts

    Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

  • Check for medical identity theft

    Review the Explanation of Benefits statements from your health insurer for services or claims you never received, which can signal misuse of your medical identity.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
