US short of options to punish NKorea for serious cyberattack

WASHINGTON (AP) — The Trump administration vowed Tuesday that North Korea would be held accountable for a May cyberattack that affected 150 countries, but it didn't say how, highlighting the difficulty of punishing a pariah nation already sanctioned to the hilt for its nuclear weapons program.

The WannaCry ransomware attack infected hundreds of thousands of computers worldwide and crippled parts of Britain's National Health Service. It was the highest-profile cyberattack North Korea has been blamed for since the 2014 hack of Sony Pictures after it produced "The Interview," a satirical movie imagining a CIA plot to kill leader Kim Jong Un.
