Our DLP watermarks documents by injecting a signed DLL into WINWORD.EXE on print. The Cortex agent blocks the injection — page prints with no watermark, DLL never loads. Works fine with the agent removed. Persists in Report mode, generates no alert/prevention event.
Tried a Disable Prevention rule (signer + thumbprint, all modules, global) — no effect, so it's not a prevention module. A Disable Injection & Prevention rule works but is time-limited and process-wide.
Has anyone made a permanent, signer-scoped exception so a trusted signer can inject into a protected process (Office) — without disabling injection protection for Word entirely? Which module actually enforces this? Thanks.
