The Bitcoin marketplace NiceHash has been hacked, and over $64 million dollars worth of Bitcoin has been stolen in a matter of moments.
On Wednesday, several NiceHash users reported some unusual activity in their BTC wallets, several of them found their wallets to be completely empty. Soon after these reports, NiceHash announced that it would be temporarily closing for maintenance.
12 hours after the service went offline for this maintenance, NiceHash released a statement saying that they had experienced a security breach which was compromising their payment services and that the service would continue to be closed for the next 24 hours while they investigated the situation.
Several users began tweeting NiceHash, saying that their money had been stolen.
“Either I got hacked or something is up,” tweeted Erik Callesen, showing an outgoing transaction of $56 million he claims to have not made.
NiceHash has not confirmed the total amount of Bitcoin that was stolen, however, CoinDesk has reported that as much as 4,736.42 in Bitcoins were stolen, which at the time of the report was worth over $62 million. With the jump that Bitcoin price has recently taken, the total amount of Bitcoin stolen could be as much as $70 million now, if not more.
There have been several fingers pointed at a particular Bitcoin wallet address that, when it opened on Tuesday at 9:07 pm, went from a balance of 0.01 Bitcoin to a balance of 4,655.25 Bitcoin in just ten minutes, with over 3,000 transactions made by the user – and the number has climbed since.
Confirmation has been made by RT America after looking into the suspicious activity reported by the users claiming to have been hacked, and it looks like their money was indeed transferred to the mysterious Bitcoin wallet address.
NiceHash has commented that they have begun an investigation into the matter, and that “relevant authorities and law enforcement” have been notified. They are “co-operating with them as a matter of urgency.”
NiceHash head of marketing Andrej P. Škraba has said that the hack was “a highly professional attack with sophisticated social engineering.” Despite this, the company assures its users that it is “fully committed to restoring the NiceHash service with the highest security measures at the earliest opportunity.” However, how the company will be able to rectify matters if total compensation is unable to be achieved remains up in the air.
In the meantime, NiceHash is encouraging users to change their passwords, both on their NiceHash accounts as well as on other services.
