You're likely being downvoted because the Github profile looking like east Asian isn't evidence of where the attacker/attackers are from.

Nation states will go to long lengths to disguise their identity. Using broken Russian English when they are not Russian, putting comments in the code of another language, and all sorts of other things to create misdirection.

That's certainly true-- at the very least it "seems" like Asian, but it could very well be from any nation. If they were patient enough to work up to this point they would likely not be dumb enough to leak such information.

Otoh with these kind of kneejerk "antiracist" reactions the best way to disguise a chinese operative becomes to prentend you're chinese.
