What it detects

This rule detects Entra ID sign-ins using the Resource Owner Password Credential flow against the Azure CLI application, matching the LSHIY password spray campaign. The ROPC flow submits usernames and passwords directly and cannot satisfy interactive MFA, making it a favored channel for spraying against tenants with conditional access gaps. Repeated ROPC attempts against Azure CLI indicate automated credential guessing.
