SEOUL, March 26 (Yonhap) -- A week after a massive cyber attack on the country's major broadcasters and banks, several associations here for North Korean defectors and local media outlets that primarily focus on the communist country suffered a paralysis of their Web sites in what appeared to be a hacking attack, officials of the entities said Tuesday.

The home page of the Daily NK, which is run by opponents of the North Korean government to provide detailed coverage of the communist nation, and those of several other associations for North Korean defectors were also paralyzed, according to the groups.
