Chick-fil-A confirms some customer accounts breached.NurPhoto via Getty ImagesChick-fil-A’s corporate slogan is “we didn't invent the chicken, just the chicken sandwich.” While I’m not going to get into the accuracy of that statement, what I will say is that the fast-food outfit didn’t invent password stuffing, but some of their customers have been served up a side of it nonetheless. A July 20 data breach notification letter sent to impacted customers stated: “We recently identified suspicious login activity to certain Chick-fil-A One accounts. Following a careful investigation, we determined that unauthorized parties launched anautomated attack against our website and mobile application between June 17 and June 19, 2026 using account credentials (e.g., email addresses and passwords) obtained from a third-party source.”ForbesFBI Issues New ‘Fake Feds’ Warning As Attacks ContinueBy Davey WinderWhat Information Was Accessed By The Chick-fil-A Account Hackers?Although the number of accounts affected has not been released, a July 13 determination by Chick-fil-A concluded that the attacker may have accessed personal information of those customers.

Fast-food and retail apps are a lucrative treasure trove of stored payment data and loyalty rewards.”A Chick-fil-A spokesperson stated that as soon as the password stuffing incident was discovered, “we immediately took action to protect customers’ accounts, which included forcing log-outs of affected accounts and removing any stored payment methods.”MORE FOR YOUHow to reset your Chick-a-Fil passwordChick-a-FilThe Chick-fil-A security team has already reset account passwords, meaning that impacted customers would update their password as soon as is possible. Customers are advised to use a strong password unique to their account and not shared with any other service or platform. I would further recommend using a password manager to both create such passwords and to ensure that they are indeed used only once.
