NiceHash notified all the major exchanges of bitcoin and mining sites about the infringement to track and possibly recover the stolen currency.
It seems that the hackers entered the NiceHash system using the credentials of one of the company's engineers.
"Given the complexity and security of the systems deployed, this appears as an incredibly coordinated and highly sophisticated attack," said Kobal.
He did not say whether the funds had been taken from the accounts of NiceHash users as well.
"While the full extent of what happened is not yet known, we recommend, as a precaution, that you change your passwords online," NiceHash warned users earlier.
"In addition to conducting our own investigation, the incident has been reported to the relevant authorities and authorities and we are cooperating with them urgently," he said.
