Goal

Detect when a user logs in with a breached password.

Strategy

Auth0 logs an event when a user logs in with a breached password. When this event is detected, Datadog generates a MEDIUM severity Security Signal.

You can see more information on how Auth0 detects breached passwords on their [documentation][1].

Triage and response

  1. Inspect the policy and user location to see if this was a login from approved location
  2. See if 2FA was authenticated
  3. If the user was compromised, rotate user credentials.
