That's not how covert operations works. More likely is just a series of subtle moves to get "trusted" assets into the right places, followed by coordination outside of corporate channels to implement the backdoor. You'd have trusted agents actually implementing and using the backdoor, and less trusted assets (ideally, to allay suspicion, people not of your nationality that you've leveraged via MICE or some other mechanism) to look the other way and generally act like useful idiots.
