It was found that Internet access to major North Korean institutional sites was not smooth this morning, following yesterday (26th).
As of 7 a.m. today, access failures occurred to sites such as the Rodong Sinmun, the official newspaper of the North Korean Workers' Party, the Korean Central News Agency, the Ministry of Foreign Affairs, Koryo Air, and the cabinet newspaper 'Democratic Chosun'.
Some sites were connected for a while, but after a while, the window does not open due to disconnection or a long waiting time.
Regarding this phenomenon, there are speculations that the cyberattacks aimed at North Korea have caused great damage, and that damage recovery has not been done yet.
Yesterday Reuters reported, citing British internet security researcher Junard Ali, that a denial of service, so-called DDoS attack, had occurred against North Korea.
DDoS is a cyberattack that puts a burden on the server through a large number of connection attempts.
Ali said that during the cyber attack, all traffic to and from North Korea was down at one time, and some connection failures and delays continued after that.
The DDoS attack on major North Korean institutions took place for about 6 hours from yesterday morning, and after that, the server handling email was restored, but the other institution sites did not recover from access failures, Ali explained.
North Korea has a separate organization related to hacking, such as the General Bureau of Reconnaissance, and is conducting hacking crimes around the world, according to intelligence officials.
It is a hacking attack against governments and companies, virtual currency exchanges, and North Korean experts in each country.
In that regard, there is also an analysis that North Korea, which is evaluated as having the best hacking attack capability in the world, is not responding well to recovering the attack it suffered.
