Understanding Credential Stuffing
Credential stuffing is an attack where hackers use automated tools to test large lists of stolen username/password combinations against websites. Because many people reuse passwords, credentials stolen from one breach often work on other sites.
Attackers typically use botnets and proxies to try thousands of login combinations per hour, looking for valid accounts they can exploit for fraud or resale.
Why Credential Stuffing Matters for Shopify Stores
Credential stuffing attacks target customer accounts on Shopify stores, aiming to access saved payment methods, make fraudulent purchases, or steal loyalty points. Protecting against these attacks requires rate limiting and bot detection.
