The most closed country on earth — North Korea — is now denying its involvement in one of the biggest corporate hacks in history.
Someone attacked Sony Pictures Entertainment last week and made public troves of stolen data, including five unreleased films, medical records and salaries of nearly 7,000 global employees. But before a recent denial — another North Korean diplomat played coy about the country's involvement.
That North Korea could be capable of a sophisticated hack may seem counterintuitive, since the nation known as the Hermit Kingdom is so cut off from the rest of the world. But North Korea watchers say its cyber-espionage skills are actually quite developed.
