Sure. I install a faraday cage around my home. You come over and your cell phone doesn't work. I did this knowing that your cell phone wouldn't work, but I haven't actively done anything to your phone. I've passively interfered with its operation by actively targeting something else -- its dependency on being able to transmit and receive EM signals beyond the confines of my home which are currently blocked by my faraday cage.
Now not knowing the specifics of what North Korea did, I'm only speculating. If they sent a high-intensity EM beam aimed directly at the drone that disrupted the drone's systems then that would be an active measure. On the other hand, if they flooded their airspace such that GPS signals coming from a North-bound direction did not arrive at the drone's location then that would be a passive measure. It's the difference between overloading the drone's GPS receiver (active) and producing a signal inverse to the GPS signal, thereby canceling it out and little to no signal arrives to the drone (passive).
