North Korea has allegedly been involved in unleashing cyber attacks against South Korean bitcoin exchanges and other blockchain companies. These attacks are possibly the result of economic sanctions against North Korea.

A United Press International article elaborated; “The CWIC Cyber Warfare Research Center in South Korea stated a domestic exchange for bitcoin, the worldwide cryptocurrency and digital payment system, has been the target of an attempted hacking…other targets include South Korean financial technology companies and smaller businesses that use online financial tools.”
