Goal

Correlate a successful credential stuffing login with a user assumed a role.

Strategy

Correlate the Credential Stuffing Attack on Azure and Azure AD member assigned Global Administrator role signals based on the ARN: {{@userIdentity.arn}}.

Triage and response

  1. Set signal triage state to Under Review.
  2. Determine if the credential stuffing attack was successful.
    • If the login was not legitimate:
      • Investigate the user using the User Investigation Dashboard
      • Rotate credentials on the credential stuffed account
      • Enable MFA if it is not already enabled
    • If the login was legitimate:
      • Triage the signal as a false positive
