I would actually be somewhat happy if it were; at least it'd peg the DPRK's malware capability at "rank amateur", only a threat to actors with extremely negligent security… …if 'happy' is the right word to use about nation-states of any size sabre-rattling with malware, and I'm not sure that it is! But it's clear whoever did this probably isn't a highly technically competent threat (or, at least, are pretending not to be).
