Highly doubtful. More than likely someone is picking targets here. Going for food supply is a war crime. So it could be an extremely hostile nation state. Or some really psychopathic disgruntled person/group. If there's no ransom it strongly leans toward a nation state in my opinion. A lot of turmoil between Europe and Russia+the us lately. That's my guess.

Attacking power plants, grocery stores, sending drones into multiple countries over and over, setting up gun/dead-drops in German forests, sabotaging warehouses and factories, etc wasn't enough?

The hybrid war goes DEEP and has been happening for a long time. https://en.wikipedia.org/wiki/Russian_sabotage_operations_in...
