American officials were able to identify North Korea to be the mastermind of the recent Sony Pictures Entertainment cyber-attack last November 2014 basing on a previous and successful NSA break in the country’s computer systems. The growing concern regarding North Korea’s increasing capabilities led the agency to particular Chinese networks, which basically connects N Korea to the world.
The NSA then monitored said connections in Malaysia that hackers from North Korea often use, the agency then penetrated valuable data with the collaboration of other American allies and South Korea. The US never explicitly had charged other governments regarding previous cyber-attacks, but the US military has no doubts regarding N Korea’s involvement.
