Cryptocurrency marketplace NiceHash has claimed that the contents of its bitcoin wallet was stolen in a security breach, with nearly $64 billion in bitcoins lost.
Slovenia-based cryptocurrency mining marketplace NiceCash allows users looking to sell their computers’ processing time for cryptocurrency mining in exchange for bitcoin. The marketplace went offline early on Wednesday, which the company claimed was due to maintenance. Soon enough, an announcement posted on the company’s social media channels confirmed users’ worst fears.
“Unfortunately, there has been a security breach involving NiceHash website. We are currently investigating the nature of the incident and, as a result, we are stopping all operations for the next 24 hours,” the team at NiceHash wrote. “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.”
NiceHash head of marketing Andrej P. Škraba told Reuters that the hack was “a highly professional attack with sophisticated social engineering”, one that saw some 4,700 bitcoins, worth some $65 million at the time of publishing, stolen from the wallet.
The company has advised users to change all their online passwords since it’s presently unclear what data the hackers were able to obtain – in addition to the stolen funds.
In addition to an internal investigation, the company further added that it had contacted the “relevant authorities and law enforcement” in order to “rectify the matter in the coming days.”
