The virtual currency's major exchange, the coin check, said that due to unauthorized access from the outside at around 3 am on 26th a virtual currency called "NEM" equivalent to 58 billion yen at the current rate Was leaked.

It is the asset that the customer has deposited, and the company is proceeding to investigate the cause by stopping trading transactions and withdrawal in the Japanese yen for most of the virtual currencies handled, but compensation And the restart of trading is not standing.

According to the company, the NEM which flowed out this time was stored in a state connected to an external network called "hot wallet". In this company, there are other virtual currencies kept in a state called "cold wallet" which is cut off from the external network and has a high degree of security.

Although the company was aware of NEM's need for countermeasures, it explains that the difficulty was technically high and the hand was not turning around due to lack of human resources.

Professor Naoko Iwashita of Kyoto University Public Policy Institute, who is familiar with the virtual currency, said, "NEM has less trading volume than major virtual currencies, so if measures were to be postponed We point out that the fact that the security measures were inadequate led to an outflow as "not exist".

Meanwhile, the Financial Services Agency (FSA) decided to receive detailed reports from the company on 28th and consider the response.
