The troll was able to spoof the Nintendo.co.jp domain because Nintendo didn’t setup their DMARC settings correctly. They have it setup but with policy “none” instead of “reject”. What a bunch of dumb asses. Such a big company doesn’t even protect their domains against spoofing. Probably why they got hacked, they don’t invest enough in IT security. Though this is typical for Japanese corporations.
