Computers at a nuclear power plant in South Korea have been compromised by a hacker, but the plant's operator says no critical data has been leaked.
The hacker was able to access blueprints, floor maps and other information
on the plant, the South Korean Yonhap News Agency reported Sunday.
Using a Twitter account called "president of anti-nuclear reactor
group," the hacker has released a total of four postings of the leaked
data since December 15, each one revealing internal designs and manuals
of the Gori-2 and Wolsong-1 nuclear reactors run by Korea Hydro and
Nuclear Power Co. (KHNP), Yonhap added. The hacker has threatened to
leak further information unless the reactors are shut down.
has insisted that the leaked information is not critical and does not
undermine the safety of the reactors. The company also played down the
threat of any type of cyberattack, saying that the reactors' controllers
are protected because they're not linked to any external networks, according to the Wall Street Journal.
hacking against KHNP nuclear plants occurs in the midst of a major hack
against Sony Pictures over its movie "The Interview," a comedy about an
assassination attempt against North Korean leader Kim Jong-un. The FBI has accused North Korea of orchestrating the Sony hack,
though the country has denied any involvement. As a further response,
North Korea suggested a joint investigation into the hack with the US
but then accused the US of being involved in the making of the film, according to The Guardian.
the increased tension, no fingers have been pointed at North Korea for
the hacking against the KHNP power plants. An official at KHNP told
Reuters that the hacking appeared to be the work of "elements who want to cause social unrest," but added that he had no one specific in mind.
Government officials looking into the incident were able
to trace the hacker's IP address to a PC located in a specific location,
Yonhap said. Investigators have been sent to the location as well as to
the plant's reactors to probe further.
