Chick-fil-A says a recent security incident may have exposed personal information tied to a limited number of customer loyalty accounts. The company disclosed the issue after identifying suspicious login activity involving certain Chick-fil-A One accounts.

According to the company, affected customers were contacted after the activity was detected. The notice suggests the incident was linked to unauthorized access attempts rather than a broader systemwide disruption, though Chick-fil-A has indicated that some account data may have been exposed.

The disclosure adds to growing concerns around account security for loyalty programs, which often store customer details and purchasing information in one place. Incidents involving suspicious logins can create risks for users if attackers gain access through compromised credentials or other unauthorized means.

Chick-fil-A said the event involved only a limited number of accounts, but the company’s alert highlights the importance of monitoring loyalty profiles for unusual activity. The restaurant chain has framed the incident as a targeted security issue affecting some customers rather than its entire user base.
