There was the “unauthorised access” of the exchange detected by the company on Friday. After that exchange stopped trading of all cryptocurrencies besides bitcoin. 

On the Friday NEM coins were in a hot wallet instead of cold wallet, which is more secure and kept offline, because of the technical difficulties and a shortage of staff. 

The bitcoin exchange of Tokyo admitted that 850,000 coins, worth around $480m, was stolen from its vaults and after that collapsed.
