How would Ukraine know this??? Are they inspecting exploded shells and determining it to be north Korean? If so, how? And why actually? Why would they inspect backfired explosives that belonged to the enemy?
It's called military intelligence, and yes of course that's what Ukraine does. Knowing how your enemy is armed and what specific advantages and weaknesses their equipment has can literally help to win a war. They'd be stupid not to inspect any remnants.
Ukraine also engages in a fair amount of propaganda (so much so that US and UK intelligence regularly contradict them), so asking for evidence isn't too unreasonable.
