Be careful where you eat your chicken – your personal data might be in jeopardy. Chick-fil-A recently fell victim to a credential stuffing attack, leading to thousands of compromised Chick-fil-A One accounts (and angry customers).

About the attack

Between June 17 and 19, 2026, unidentified hackers utilized automated tools and login information from third-party sources to breach over 2,200 Chick-fil-A One accounts. Hackers gained access to a plethora of personal information, including customer names, the last four digits of customer payment cards, birthdates, addresses, and more.

The aftermath

Although the cybersecurity incident took place in June, Chick-fil-A didn’t become aware of it until July 13, after identifying suspicious login activity on a handful of Chick-fil-A One accounts. The fast-food company then launched an investigation and determined that multiple accounts had been breached. An “undisclosed number of customers” received a letter from the company on July 20, informing them that their accounts may have been compromised. Customers across the nation were affected by the incident, including residents of Washington D.C., New York, and Texas, among others.

Following the attack, Chick-fil-A took action by returning impacted Chick-fil-A One accounts to their original balances, deleting saved payment methods, force-logging out any accounts with suspicious activity, and even giving rewards to customer accounts effected by the incident. Nevertheless, the company is now facing potential legal action.
