North Korean Hackers Suspected in 'WannaCry' Ransomware Attacks

As evidence mounts that North Korean hackers may have links to the ransom assaults that destroyed more than 200,000 computers, their motives appear twofold: financial gain — which does not appear to be turning out so well — and proof that Pyongyang has the means to cause significant damage, with or without a nuclear weapon. Over the past year, the same North Korean hacking unit that hit Sony Pictures was linked to cyberattacks at banks in Vietnam and the Philippines, and to a breach at the Bangladesh Central Bank that resulted in the theft of $81 million.
