according to this article:

https://learn.microsoft.com/en-us/entra/identity/authentication/howto-mfa-mfasettings#report-suspicious-activity

when a user reports a fraudulent MFA (i.e. pressing 0# on the phone) the user is supposed to be made "high risk" and IT people should be able to see this report in:

Sign in logs

Audit logs

Risk Detection report

i have tested this and the only thing that happens is i see a "failure" in the users sign in logs. none of the other things happen and the user is not marked as "high risk" i do have it enabled:
User's image

Microsoft Entra ID

    Hello Michael Menzie,

    Microsoft Entra ID Protection determines the likelihood that a sign-in request is unauthorized for each login attempt.

    To test risky sign-in a simulation with an anonymous IP address can be easily and quickly performed using the Tor Browser.

    Start the Tor Browser and navigate to https://aka.ms/myapps

    Sign in with your account and the sign-in will appear in the Risk Detection report after approximately 15 minutes

    The below document shows the types of risk detections in Entra-ID Identity Protection.

    https://learn.microsoft.com/en-us/entra/id-protection/concept-identity-protection-risks

    The reason why your sign-in attempt from phone is not showing as risky sign-in is that you use your phone to sign-in regularly, Microsoft Algorithms will identify those sign-ins as legitimate sign-ins.

    When you try from a device which you didn't sign-in regularly from un-known ip address (external and also not from your home) it might show as risky sing-in attempt.
