NiceHash, the largest Bitcoin mining marketplace, has been hacked, which lost more than $70 million USD worth of Bitcoin.
Most of the major hacking and breaches concerning Bitcoin happened early this year including CoinDash, Veritaseum and Etherparty. Considering the skyrocketing price of Bitcoin, attackers are now focusing their skills and resources towards such cryptocurrency. Since a successful cryptocurrency hack generates bountiful outcome, services that offer exchange and trade of cryptocurrency became the primary target of cyber-attacks.
NiceHash is a crypto-mining marketplace that connects sellers of hashing power (miners) with buyers of hashing power.
On December 6 2017, NiceHash users have reported that their BTC wallets were emptied. The extent of the attack was not verified by then, but users shared and circulated among affected users a BTC wallet which shows a balance of 4,736 BTC. The following is the screenshot of the Bitcoin address:
CEO Marko Kobal and co-founder Sasa Coh officially announced over a video stream that NiceHash has been hacked. The said cyber-attack resulted in the loss of over 4,700 BTC or an amount equivalent to more than $70 million dollars from Bitcoin wallets of thousands NiceHash user accounts.
NiceHash website has been shut down since the said attack, and displayed the following announcement to its users:
Since the extent and damage of the attack executed was considerably large, and that the BTC amounts were siphoned in a very short span of time, it proves that the attack was properly laid upon and has extensive resources. There might also be an inside job which purposely let the attackers into the NiceHash systems.
NiceHash is recommending its customers to change their passwords—both on NiceHash and other services, if they are using the same credentials.
