Aflac Incorporated has filed a data breach notification with Montana regulatory authorities regarding an incident that began on June 12, 2025. The filing, dated December 19, 2025, indicates an unspecified type of breach where an unknown number of individuals' personal information may have been exposed.

Currently, Aflac reports that an investigation into the scope and impact of this event is underway. Public records at this time do not specify the exact categories of personal information that were involved in the breach, referring to it only in general terms such as 'the information involved' or 'your data'.

Given the ongoing investigation, individuals who have been or may be associated with Aflac are encouraged to exercise caution and remain vigilant. Monitoring for any unexpected communications or unusual activity related to their personal information is a prudent first step.

Regularly review financial account statements and credit reports for any unauthorized transactions or suspicious inquiries. Most financial institutions and credit bureaus offer free monitoring tools that can help detect fraudulent activity promptly.

Be wary of unsolicited emails, phone calls, or text messages that ask for personal details. These could be phishing attempts designed to exploit information that may have been compromised.

This information is derived from official regulatory filings made public by Aflac Incorporated. As the investigation progresses and more details become available, updates will be reflected in public records.

What to do if you were affected

These general steps can help limit the risk of identity theft and fraud after any data breach.

  • 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.
