Something like a missile attack on a Samsung factory is so easy to investigate and get conclusive evidence about what happened. Within hours or days we would know with almost certainty if it was an act of war or something else (accidental firing by the South Korea military or something...).

Consider something like Stuxnet, it took years before it was truly discovered and attribution could be made, at least in way which would hold up in a lawsuit about insurance claims.
