NiceHash, a cryptocurrency mining marketplace, confirmed daylong speculation that its security has been breached and “the contents of the NiceHash Bitcoin wallet have been stolen.” Its users said in online forums that their balances are zero and that the money was moved to a Bitcoin wallet that shows about $60 million being added today.
A press release from NiceHash posted on Reddit and Twitter said that the company’s security has been breached.
Previously, WikiTribune was in contact with company adviser Andrej Nabergoj, who said that NiceHash was “assessing the situation and working with the authorities.” WikiTribune initially identified Nabergoj as CEO, but he subsequently clarified his position.
NiceHash is a place for users to buy “hashing power,” that is computing power for mining different cryptocurrencies such as Bitcoin. On Tuesday, the price of Bitcoin surged to $13,000, as reported by Business Insider.
About $60 million from NiceHash users has apparently been moved to a single external wallet pointing to this address.
This security breach of NiceHash makes it one of the biggest cryptocurrency breaches ever.
The company’s first tweet regarding maintenance was posted earlier this morning, and it posted another four hours afterwards, which only added to the concerns expressed on social media by people identifying themselves as NiceHash customers. Users on the Reddit page also said that the company stopped responding to support queries around a day or two ago.
