If i understand you so well, you are literally saying the Korean government is sponsoring the Lazarus groups who keeps hacking exchanges, or you are just asking to be sure? That will be a false accusation because no government will publish any news that they are in support of cybercrime. If investigations is done and they have to trace all the money stolen from these CEX exchanges down to the Lazurus group, then the Korean government will be causing a conflict between nations.
