Chick-fil-A has alerted its customers to change their passwords for the Chick-fil-A One app following an unauthorized access incident. The breach, identified in June 2026, involved a credential stuffing attack that compromised a portion of loyalty accounts.
Details of the Security Breach
The company’s investigation revealed that the attackers executed an automated credential stuffing operation on its digital platforms between June 17 and June 19, 2026. This method exploits email and password pairs obtained from other data breaches, assuming users may have reused these credentials.
The attack affected users in ten states across the United States. In response, Chick-fil-A issued data breach notifications and provided security recommendations to those impacted.
Steps Taken by Chick-fil-A
To mitigate the breach, Chick-fil-A reset passwords for affected accounts, logged out active sessions, and removed stored payment methods. Additionally, they urged all Chick-fil-A One users to change their passwords, regardless of direct notification receipt.
Exposed data potentially includes customer names, email addresses, mobile payment numbers, and partial payment card information. Attackers may have accessed loyalty balances and transaction histories, increasing the risk of fraud and phishing attempts.
Recommendations for Customers
Chick-fil-A clarified that the credentials used were from unrelated third-party breaches. This incident highlights the risks associated with password reuse and the importance of robust account security.
Experts recommend users create unique passwords and enable multi-factor authentication (MFA) using a verified phone number for enhanced security. Customers should also check their account activities, bank statements, and be cautious of phishing communications.
This breach underscores the attractiveness of loyalty apps to cybercriminals due to the valuable data they hold. Chick-fil-A’s situation serves as a reminder of the continuous need for vigilant cybersecurity practices.
