Suspicious RPC Traffic to Critical Assets for Authentication Coercion

Detects Remote Procedure Call (RPC) attempts targeting critical assets, such as Domain Controllers, where the call includes a UNC path pointing to an external IP address. This is a strong indicator of an authentication coercion attack (e.g., PetitPotam, DFSCoerce) where an attacker is attempting to force the critical asset to authenticate to a listener they control to capture credentials.
