North Korean hackers may have stolen highly classified military documents, including US-South Korean wartime "decapitation strike" plans against the North, a South Korean legislator is quoted as saying.
The information, that included wartime contingency plans drawn up by the US and South Korea, was from the country's defence ministry, according to Rhee Cheol-hee, a South Korean lawmaker.
In an email comment sent to Bloomberg, Bong Youngshik, a researcher at Yonsei University's Institute for North Korean Studies in Seoul, said the trip would fit the "appetite for high theatrics" often exhibited by the USA president.
Mr Rhee said 235 gigabytes of military documents were leaked, however the content of almost 80 per cent of that has not yet been identified. Political experts believe that the US President was hinting the possibility of a military action against North Korea if the country continues its blind nuclear ambitions.
At the weekend, the USA leader said efforts with Pyongyang had broken down and that "only one thing will work".
Rhee made his claims about the alleged cyberattack to South Korean reporters, citing documents obtained from the Defense Ministry under a freedom of information request.
Pyongyang has denied that it was behind the latest cyber attack, criticizing Seoul for "fabricating" the claims.
South Korean officials in May initially accused the communist dictatorship of breaking into its secure networks, Yonhap reported.
The teams held drills in mid-September involving an attack on the South Korea-U.S.
Under one scenario, Britain's 65,000-tonne carrier, with a crew of 700, could be escorted by Type 45 destroyers and Type 23 frigates to join United States warships in the Korean peninsula, reports Larisa Brown, the newspaper's defence and security editor.
When the hacking attack was found out a year ago, the Defense Ministry blamed North Korea.
Anton Morozov said North Korea is aiming to increase the range of its ballistic missiles from 3,000km to 9,000km - which could reach the US Pacific island of Guam.
The North Korean leader, who has continued to add to tensions with continued nuclear missile tests, addressed Mr Trump's previous comments and insisted "a frightened dog barks louder".
