PhantomRPC: A New Windows RPC Vulnerability Enables Privilege Escalation

The PhantomRPC technique is related to architectural characteristics of the Microsoft Windows RPC (Remote Procedure Call) mechanism. The core issue is that an attacker can deploy a rogue RPC server that intercepts requests from the system or services while impersonating a legitimate component.

By exploiting the impersonation mechanism, an attacker with limited privileges can escalate them to the SYSTEM level. The vulnerability is not tied to any single specific component and may potentially affect multiple versions of Windows.
