As reported by the New York Times:
WASHINGTON — Twenty nations with significant atomic stockpiles or nuclear power plants have no government regulations requiring minimal protection of those facilities against cyberattacks, according to a study by the Nuclear Threat Initiative.
The findings build on growing concerns that a cyberattack could be the easiest and most effective way to take over a nuclear power plant and sabotage it, or to disable defenses that are used to protect nuclear material from theft. The countries on the list include Argentina, China, Egypt, Israel, Mexico and North Korea.
