The digital currency exchange NiceHash claims that the contents of its bitcoin wallet were stolen in a security breach and one executive said that nearly $64 million had been lost, reported Reuters.
The head of marketing at NiceHash Andrej P. Škraba said that the hack was “a highly professional attack with sophisticated social engineering” and that approximately 4,700 bitcoin, which were nearly worth $63.92 million at current prices, were lost. He further exclaimed that the company was cooperating with local authorities, however refused to say anything further on the subject.
Earlier, Slovenia-based NiceHash stated on its website that it had paused all its operations for 24 hours as it investigated the breach.
NiceHash advised users to change online passwords, saying it was still trying to understand what had happened during the incident.
“We understand that you will have a lot of questions, and we ask for patience and understanding while we investigate the causes and find the appropriate solutions for the future of the service,” the company said in its statement.
