Washington is chasing North Korea's cyber thought! Park Jin-hyuk, accused of working within the North Korean cyber unit, is one of the most wanted by US authorities after being accused of involvement in major international cyber attacks. The most notable actions attributed to him include: * 2014: Sony Pictures hacked, data and movies leaked. * 2016: $81 million was stolen from the Central Bank of Bangladesh. * 2017: Participation in the WannaCry virus attack that infected more than 300,000 devices in 150 countries. Washington accuses North Korea of using proceeds from piracy to fund its military, missile and nuclear programs. The suspect is believed to still be inside North Korea, making his arrest a major challenge for US authorities.
