Cryptocurrency mining marketplace NiceHash announced Wednesday that it suffered a security breach that resulted in a loss of as much as $62 million in Bitcoin.
The announcement came after hours of speculation sparked by the service being unavailable for the better part of Wednesday. Several reports from users noted that their Bitcoin wallets associated with NiceHash had been emptied.
While NiceHash originally claimed to be “under maintenance” during the outages, the company admitted that it had suffered a security breach involving the NiceHash website that resulted in loss of funds.
“Our payment system was compromised and the contents of the NiceHash Bitcoin wallet have been stolen. We are working to verify the precise number of BTC taken,” the company said in a statement , calling the breach “a matter of deep concern.” The company also apologized to its users for “any inconvenience” the breach may have caused.
While NiceHash has yet to place an amount on how much is stolen, a Bitcoin wallet address highlighted by NiceHash users that appeared Wednesday and has received a large deposit out of nowhere contains 4,736.42 BTC, valued at about $62 million at current prices.
