Millions Vanish from Crypto Exchange

Millions Vanish from Crypto Exchange

Units of the cryptocurrency NEM worth US$530 million (RM2 billion) were taken - based on the exchange rate on Friday - exceeding even the US$480 million in bitcoin stolen from the MtGox exchange in 2014.

"We realize that this illicit transfer of funds from our platform and the resulting suspension in services has caused vast distress to our customers, other exchanges, and people throughout the cryptocurrency industry, and we would like to offer our deepest and humblest apologies to all of those involved", Coincheck said in a statement.

However, while the illicit transaction was valued at about 58 billion yen, or A$660 million, the amount refunded will be 46.3 billion yen or A$523 million. If the figure is confirmed, the crypto burglary will be the largest to date.

However, the Coincheck breach was not detected until 11:25 Japan time.

The regulator said it has yet to confirm whether Coincheck had sufficient funds for the reimbursement.

Meanwhile, the development team behind NEM has announced that it is working on an automated system that will track the stolen coins and tag all addresses that receive the "tainted" money.

The company is still considering the exact timing and methodology for the process.

"We hope everyone can understand that while we believe the community deserves to know everything we are doing, we also believe it is in the community's best interest to not publicly discuss the full detail our actions considering the security needed around our solution". Nevertheless, it had "nothing to do with NEM but rather Coincheck's lack of strong security measures", she said in a series of tweets.

Cryptocurrency exchange Coincheck's signboard is pictured in front of a building where their office is located, in Tokyo January 29, 2018.

"Along with our ongoing efforts to file applications to be registered as a Cryptocurrency Exchange Service Provider with Financial Services Agency, we will continue business".

The NEM coins were stored in a "hot wallet" instead of the more secure "cold wallet", outside the internet, Coincheck said. The weighted average price was derived using prices during the period beginning with the suspension of new purchases and sales of NEM on the Coincheck platform and ending with the release of this notice.

If necessary, it will conduct on-site inspections of other exchanges, an official told a briefing.
