Chick-fil-A Confirms Credential Stuffing Attack

Credential stuffing is one of the many forms of cyberattacks on the rise. It's a low-risk, low-cost automated method. It uses bots to access username-password combinations from past data breaches. It then uses that information to exfiltrate data from a new target system. It relies on people's habit of reusing the same login credential across various sites.

Chick-fil-A is one of the most recent victims of a credential stuffing attack. That proves that even large companies aren't exempt from these malicious attempts. Here's everything you need to know about the incident so you can stay informed.
