You don't have to be an evil North Korean to do that. Outsources have been doing it since time immemorial because they can't achieve sales in any other way (or, through direct corruption - often offshore outsourcing shops are owned by managers of their clients, who effectively use them as tools for siphoning money away).
Hopefully the fear of foreign actors will put an end to this too.
I have to hand it to North Korea on the inventive revenue streams. This is a country under sanctions for decades that has developed some of the most clever IT scams for siphoning money from the west. Between this and the Lazarus group the country has brought in Fortune 500 company kinds of money to keep itself afloat.
