The cryptocurrency mining marketplace NiceHash, which was formed in 2014 and serves as a marketplace for miners to rent out their hash rate to others has been hacked, its team said Wednesday.
Via their social media accoun, NiceHash said that “there has been a security breach involving NiceHash website” resulting in a loss of funds.
The announcement follows an hours-long outage and reports from several users that their NiceHash-associated wallets had been emptied. NiceHash previously announced that it was “under maintenance,” a message that it had posted to its official website as well but which turned out to be false.
The company wrote in its statement:
“Importantly, 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. Clearly, this is a matter of deep concern and we are working hard to rectify the matter in the coming days. In addition to undertaking our own investigation, the incident has been reported to the relevant authorities and law enforcement and we are co-operating with them as a matter of urgency.”
Though the NiceHash team didn’t disclose an exact amount, a wallet address circulated by NiceHash users suggest that it could be in the range of 4,736.42 BTC – an amount worth over than $62 million (and counting) – has been stolen.
“While the full scope of what happened is not yet known, we recommend, as a precaution, that you change your online passwords,” they wrote in the statement.
