Chick-fil-A notifies customer about personal information exposure after data breach occurred due to credential stuffing attack
Chick-fil-A company has announced that personal and account information about some of its customers may have been exposed due to a data breach. This breach occurred through the use of credential stuffing, which is not a vulnerability within the corporation’s website or mobile application.
As explained in the company note to customers, unauthorized access attempts came from bad actors using credentials stolen elsewhere. The company discovered unauthorized access attempts to customer accounts after noticing anomalous activity in the login database, and the phishing campaign occurred between June 17-19, 2026, targeting Chick-fil-A One loyalty program accounts. The corporation concluded its investigation on July 13 th and established that attackers had used compromised credentials to access the account information of some customers.
The information available to bad actors and potentially at risk of being misused varies depending on the customer’s account. It may include names, contact information, mailing addresses, phone numbers, dates of birth, and Chick-fil-A One account information like ID or QR code and mobile payment credentials. Moreover, attackers may have gained access to reward balances, gift card balances, and the last four digits of payment cards.
Although the corporation has not revealed the number of affected clients, the number exceeds several thousand.
According to the documents filed with the state, 2,182 Texas residents and 39 Massachusetts residents were impacted by the breach. However, there are also other states affected, as notifications to state attorney generals in charge of consumer protection have also been filed, including the District of Columbia.
After discovering the issue, the corporation remediated the security risks and notified the affected clients.
Moreover, Chick-fil-A took measures to enhance account security for all customers, including allowing password reset, account logout, and removing payment methods in the application. Some customers also received bonus points on their accounts as compensation for the issues experienced.
Chick-fil-A corporation acknowledges the concern caused by the data breach and assures clients that it takes customer account security seriously. Moreover, the company has recommended that customers change passwords to strong and unique words or phrases not used for other accounts.
Credential stuffing works only when the same or similar passwords are used across different accounts, so changing them to unique ones decreases the chances of experiencing another breach.
Chick-fil-A data breach demonstrates once more that it is crucial to make sure that each online account, including email, banking, and social media accounts, uses a unique and strong password.
If one suspects that an account may have been compromised, it should be changed to a strong password immediately. Also, it is essential to use multi-factor authentication when available and to monitor account activity regularly for unauthorized transactions or unauthorized access attempts.
