South Korea Nuclear Reactor Hack Traced to China....(North Korea).

South Korea Nuclear Reactor Hack Traced to China....(North Korea).(SP).

A hacker accused of illegally entering South Korea's state Hydro and Nuclear Power Company computer network used multiple Chinese IP addresses, Yonhap reported Wednesday, citing an investigation by South Korean government and prosecution officials.

The network hack has been traced to a city in China, according to the investigation. The name of the city has not been disclosed yet.


The hacker has been publishing internal information of the nuclear power company since December 15, including personal data for 10,000 company employees. The hacker has also released files containing maps, safety analysis materials and information on reactor cooling and conditioning systems of the Gori and Wolsong nuclear power plants.

On December 19, the hacker, who calls himself "president of anti-nuclear reactor group," demanded the shut down of both the company's Gori and Wolsong nuclear reactors.

Messages from the hacker warned that if the Company does not close the reactors by December 25, he will "open to the world 100,000 pages of data that have not yet been revealed," according to Yonhap.

This is most likely a reference to the North Korean hackers reportedly operating from China (here are pictures of the Chilbosan hotel in Shenyang where members of Unit 121, North Korea’s computer network operations team, are supposedly based). One of the newspapers owned by the People’s Dailyran an article today quoting a South Korean professor as saying Pyongyang hadapproximately one thousand hackers in China, so the Chinese press at least is not categorically denying their existence.
