The blame for North Korea's persistent internet failures does not lie with the United States Cyber Command or any other state-sponsored hacker organisation. In fact, it was the work of an American man, who sat in his living room night after night, watching Alien movies and munching on spicy corn snacks—and periodically walking over to his home office to check on the progress of the programmes he was running to disrupt the internet of an entire country.
