"Unfortunately, there has been a security breach involving NiceHash website", the company wrote, adding that it was freezing all operations for at least the next 24 hours while it investigated the hack. While the company did not reveal the exact amount lost, users on Reddit spent the better part of today anxious as the service was initially "under maintenance" for 12 hours amidst suspicious transactions on the blockchain that saw 4,736.42 BTC taken from Nicehash and their Nicehash internal wallets reporting zero balances.
NiceHash allowed users to mine for other cryptocurrencies and paid them in bitcoin.
NiceHash, a cryptocurrency marketplace, has disclosed that the content of its bitcoin wallet had been stolen in a security breach.
Site operators said they are still working to evaluate the total number of Bitcoin funds that were stolen, but users who had earnings stolen said Bitcoin funds were rerouted to a wallet address now storing 4,736.42 Bitcoin - over $62,6 million at today's Bitcoin price ($13,450). However, as this incident demonstrates, cloud mining services subject users to additional risks versus operating one's own hardware.
While miners are waiting for official news from NiceHash, the stolen money was tracked to a single Bitcoin wallet. Users mention that their wallets have been emptied and the bitcoins are now in a wallet that received 4736 bitcoins on Wednesday, currently, that entails a total value of 51 million euros, roughly 56 million Dollars. Nicehash has indicated that they have reached out to and are cooperating with the relevant authorities, but unless they are able to find the individual (s) responsible and recover the massive amount of bitcoin it is not looking good.
We would not exist without our devoted buyers and miners all around the globe. We will endeavor to update you at regular intervals.
In the meantime, they advised users to change all of their online passwords, as it is presently unclear what data the hackers were able to obtain in addition to the stolen funds.
We are truly sorry for any inconvenience that this may have caused and are committing every resource towards solving this issue as soon as possible.
