Course a better result could be obtained by sinking a NK sub, or three. They are noisy, by diesel electric standards anyway, and should not be all that hard to find. Although their mini-subs of the Sang-O class, which can have 2-4 torpedo tubes are pretty small and probably quite a bit quieter as well. But they can't get far from port, or a mother ship.

Sub sinks, no one sees. Deniability, but the NKs would get the message.

That’s the ticket. Hunt all their subs at the same time and be done with it.

This may have already happened.
