A member of the hacker group Anonymous said Monday it plans a new cyber attack on North Korean Internet networks that would affect nuclear facilities.

The group attacked North Korean Internet sites last Thursday including Uriminzokkiri, its main Internet-based media and propaganda outlet.

A Korean member of Anonymous who uses the Twitter account @Anonsj said in an online discussion that the hacktivist group wants to break into the communist country’s Kwangmyong national Intranet on June 25. The date marks the start of the Korean War (1950-53).

The hacker, who remained unidentified, said that in the next attack, Anonymous members not only want to attack the government’s homepage, but will try to steal personnel data of North Korean leaders, and even hack into the North’s nuclear facilities.

The hacker said actions are under way to create a so-called Ninja Gateway so outsiders can gain access to the closed Intranet, which is not connected to the World Wide Web.

The hacktivist group member added that the gateway will also allow people in North Korea unrestricted access to the Internet, which could allow an inflow of democratic messages.

He said the June 25 attack will be led by Anonymous Korea, the local branch of the group.

“We have no superiors with all activities led by individuals,” the hacker claimed.

The North Korean sites attacked by the group remained out of commission on Monday.

Yonhap News Agency, which has been monitoring the affected sites, confirmed that while the website of Uriminzokkiri was repaired over the weekend, its Twitter account remained disabled with “Tango Down” messages popping up on any attempt to view the content.

“Tango Down” is a commonly used term by hackers to point out that they have paralyzed and defaced a site.

Anonymous claimed its attack was made to call on Pyongyang to stop making nuclear weapons and threatening the world with nuclear war.

Aside from Uriminzokkiri, which is run by the Committee for the Peaceful Reunification of the Fatherland, the websites of the Anti-Imperialist National Democratic Front, Our Nation School, Ryomyong and the Ryugyong Clip sites, operated by Pyongyang or pro-North Korean organizations, remained offline.

However, websites of the Rodong Sinmun, an organ of the ruling Workers’ Party of Korea, the Korean Central News Agency, Pyongyang’s official news wire service, and the Web portal site Naenara were working normally.
