What it detects

This rule detects requests to the MFA relay endpoints of the AWS console phishing kit that intercept second-factor codes delivered by email, SMS, or authenticator app. The kit prompts victims for their one-time codes and forwards them so the operator can complete authentication in real time. Traffic to these email, sms, and gauth relay paths on a login-lookalike host indicates active MFA interception.
