North Korea yesterday angrily dismissed reports linking its isolated regime to the global cyberattack that held thousands of computers to virtual ransom, reports AFP. Up to 300,000 computers in 150 countries were hit by the WannaCry worm, which seizes systems and demands payment in Bitcoin to return control to users. The code used in the latest attack is similar to that used in past hacks blamed on Kim Jong-Un's regime, leading some to point the finger at Pyongyang. But the North has now denied the claims, notably but not exclusively advanced by South Korean experts, and hit back Friday to accuse its opponents of spreading propaganda. "It is ridiculous," Kim In-Ryong, North Korea's deputy ambassador to the United Nations, told reporters, suggesting Washington and Seoul were behind the allegation.
