CEO of CrowdStrike, George Krutz, has mentioned once, that North Korea is buying bitcoins to be able to launch a series or cyber attacks.
There were numerous reports that North Korea is using cryptocurrency, bitcoin in particular, to launch cyber attacks on its Southern neighbour. The recent South Korea exchange bankruptcy, that was caused by a cyber attack, is one more proof that North Korea has significant capabilities in handling cyber space, even though it was doubtful at first. As well, the “Amassing” bankruptcy demonstrated that cyber security is something that enterprises and financial institutions all around the world shall be concerned, as danger may come from an absolutely unexpected place.
The principle of the attack lies in the creation of a bitcoin cache, and stealing bitcoins from exchanges. No sanctions are feared as there are no sanctions when we speak about bitcoin transactions.
