He said: “This is significant because the US Government does not take these attribution cases lightly.
“We have been tracking this early on, we certainly agree with the US Government but I think it highlights the capabilities that North Korea has in cyber.
“What we have seen is that the increase in capabilities in the last three years and it is something that a lot of countries should be concerned about, particularly those companies that are dealing with bitcoin and cryptocurrencies.”
Mr Kurtz added that he believed the rogue state to be “building a cache of bitcoin”.
He said: “It’s an anonymous currency, it can easily bypass any sort of sanctions because there are none on bitcoin, and the value has increased dramatically.
“It is the perfect currency for North Korea to be hoarding.”
