LJUBLJANA: A Slovenian cryptocurrency mining marketplace, NiceHash, which lost about $ 64 million worth of bitcoin in a hack on its payment system on Wednesday, said the attack was probably made from a non-EU IP address.
NiceHash matches people looking to sell processing time on computers in exchange for bitcoin.
“It is very probable that the attack was made from an IP address outside the EU,” head of marketing Andrej Skraba told Reuters on Friday.
He declined to give any more details but said NiceHash investors come from “all over the world”.
NiceHash Head Marko Kobal said in a Facebook video recording, whose authenticity was confirmed to Reuters by the company, that the hack was made by using the credentials of a NiceHash engineer.
The incident highlighted security risks to booming digital currencies.
There have been at least three dozen heists on exchanges that buy and sell digital currencies since 2011, including one that led to the 2014 collapse of Mt Gox, once the world’s largest bitcoin market.
Earlier on Friday Bitcoin fell more than 12 per cent on the Bitstamp exchange to about $ 14,500.
The Slovenian police told Reuters on Friday the investigation into the attack continued, adding no further details could be given at present.
Separately, NiceHash also confirmed to Reuters that its chief technical officer is Matjaz Skorjanc. Skorjanc had been imprisoned in Slovenia for creating the Mariposa virus that infected millions of computers around the world around 2010.
