defined.
An automated attack using credentials leaked from one breach to log into accounts on other services.
A–Z
An automated attack using credentials leaked from one breach to log into accounts on other services.
Because password reuse is universal, credential stuffing succeeds at 0.1–2% rates even against well-secured services. Defence: WebAuthn / passkeys, breach-corpus matching at registration and login, and adaptive MFA on risky sessions.
See our web application penetration testing, API security testing, network penetration testing, and cloud security audit services for how we test for and defend against this class of issue.
