This is quite possible, equally though, what is stopping all these countries from simply refusing access to territorial waters for this ship. It seems to be travelling for thousands of miles just fine, so can't claim emergency shelter, and even then the danger to third parties seems to justify any refusals. The crew is likely tiny and easy to rescue if need be.
I can imagine this being a simple ruse to annoy NATO countries and their navies too, that wouldn't be out if character, but beyond that... That would be a very petty hybrid risk.
Or maybe Russia is just trying lots of things just to see what sticks..?
From my side, while I think using a semi damaged ship as a hybrid threat would be within the Russian MO, it also seems like an easy one to protect against.
