Confirmed: Crypto Exchange Coincheck hacked

Tokyo-based cryptocurrency exchange Coincheck has verified that it has suffered what shows up to be the biggest hack in the background of the technology.

In a press conference at 23:30 JST (14:30 UST), the exchange’s president Wakata Koichi Yoshihiro and chief working officer Yusuke Otsuka approximated its loss at 58 billion yen (approx. $533 million). According to Bloomberg, which went to the meeting, 500 million NEM tokens had been used from Coincheck’s digital wallets.

Twitter posts by Nikkei appeared to indicate that the precise quantity stolen might not end up being fully known until further investigations have got been carried out into the intrusion.

But though the exact dollar shape for the incident is hard to pin down (given the volatile character of cryptocurrencies and the company’s absence of information), data suggests the shape is now at least over $400 mil, factoring for a decline in the worth of XEM, the NEM protocol’s symbol, following the incident.
