SEOUL — Major government and news media websites in South and North Korea were shut down Tuesday after anonymous hackers claimed to have attacked them on the 63d anniversary of the start of the 1950-53 Korean War.
It remained unclear who the hackers were and whether the attacks on North and South Korea came from the same sources. With the websites of its presidential office and at least one other government agency down, the South Korean government issued an alert Tuesday warning the people against cyberattacks.
The websites belonging to North Korean institutions including the main party newspaper Rodong Sinmun, the news agency Korean Central News Agency, and other entities were inaccessible Tuesday.
Officials from both countries declined to comment on what may have caused the
Internet disruptions in the isolated North, where only a handful of people use the
Internet and all websites are tightly controlled by the state.
But people who claim to be a global network of hackers called “Anonymous” had warned through Twitter that they would attack North Korean websites Tuesday. Among other things, they criticized North Korea for keeping most of its people off the Internet.
