New Device/Location sign-in along with critical operation

name: New Device/Location sign-in along with critical operation
description: |
  This query identifies users seen login from a new geo location/country and a new device, then correlates that sign-in with successful risky operations such as policy changes, MFA changes, API token actions etc. This can be an indication of an attacker gaining access to a user's credentials and then performing critical operations, which typically requires admin privileges. By detecting such patterns, organizations can quickly respond to potential security incidents and mitigate risks associated with unauthorized access and privilege escalation.
