South Korean Prime Minister Hwang Kyo-Ahn on Wednesday warned officials of possible cyber attacks from North Korea, instructing them to block such attacks in advance.
Hwang visited a centre in Seoul for countermeasures to internet infringement, saying that a close cooperation system should be built between the military, the government and the civilian sector to blockade the North Korea's possible attacks in cyberspace in advance, Xinhua news agency reported.
The prime minister said that top North Korean leader Kim Jong Un had ordered officials to muster up capability for anti-South Korea terrorist attacks, which raised possibility for the North Korea's cyber provocations.
South Korea's spy agency reportedly made mention of such an order without revealing where the agency got the information from.
Hwang said North Korea had staged massive cyber attacks against South Korea after conducting nuclear tests, instructing officials to detect such attacks at a right time and recover attacked networks successfully.
He also urged people to update security vaccines on their computers and smartphones and to refrain from opening suspicious emails or text messages in order to minimise possible cyber attacks from Pyongyang.
His comments came amid rising concerns about Pyongyang's terror attacks following its fourth nuclear test on January 6 when the it tested what it claimed was its first hydrogen bomb.
On February 7, Pyongyang launched a long-range rocket using banned missile technology.
