South Korean Nuclear Plant Hack

From Reuters:

The Korea Hydro and Nuclear Power Co Ltd (KHNP) and the government said only “non-critical” data was stolen by the hackers, and that there was no risk to nuclear installations, including the country’s 23 atomic reactors.

South Korea’s energy ministry said it was confident that its nuclear plants could block any infiltration by cyber attackers that could compromise the safety of the reactors.

“It’s our judgment that the control system itself is designed in such a way and there is no risk whatsoever,” Chung Yang-ho, deputy energy minister, told Reuters by phone.

“It is 100 percent impossible that a hacker can stop nuclear power plants by attacking them because the control monitoring system is totally independent and closed,” the official said.

100% percent impossible? That sounds like a challenge.

I’m willing to wager that “non-critical” data could be a good starting point for crafting a more sophisticated attack. But of course, nothing has ever jumped an air gap…
