South Korea is to step up cyber security amid data leaks from its nuclear power plants.
Korea Hydro and Nuclear Power Company which runs the country’s 23 nuclear power reactors said its computers had been hacked on Monday, and was investigating fresh threats from a Twitter user.
“Nuclear power plants are first-class security installations that directly impact the safety of the people,” announced President Park Geun-Hye. “A grave situation, that is unacceptable, has developed when there should have been not a trace of a lapse in a matter of national security.”
Park ordered inspections at the facilities against what she called ‘cyber terrorism’.
The nuclear operator said only non-critical data had been stolen and that their plants were not at risk.
According to a South Korean official the possible involvement of North Korea in a cyber attack has not been ruled out.
