Officials from South Korea have accused North Korea of stealing cryptocurrencies worth billions of won - equating to tens of millions of dollars.

Kyodo News reports that the National Intelligence Service (NIS) said that phishing scams and other types of attacks had yielded tens of billions' worth of won in customer funds.

It has also said that South Korean authorities are investigating whether this could be linked to the same people who carried out last month's attack on Coincheck, when more than $500 million in cryptocurrency was also stolen.

According to Reuters, South Korean parliament member Kim Byung-kee spoke about the impact of phishing scams.

He said: "North Korea sent emails that could hack into cryptocurrency exchanges and their customers’ private information and stole (cryptocurrency) worth billions of won.”

One billion won is the equivalent of £651,000.

He added that North Korea continues to attempt to hack cryptocurrency exchanges and that the South was trying to stop further attacks being carried out.

North Korea has been accused of previous hacks including attempts to steal cryptocurrencies.
