Fair challenge, you're right that there's nothing sophisticated about this type of activity, but if you look at Lazarus activity this is their ttp. I mentioned TraderTraitor, go look them up (that sounds terse, it's not meant to be). They stole a couple of hundred million dollars in the past 6 months. They're not particularly sophisticated in terms of ttp, but because they're a nation-state actor they it's an entirely different threat model than script kiddie. Attribution is hard, but if we're talking about defending, there's little cost to assuming Lazarus-style threat actor.
