An un-named hacker has been sued by China-based Bitcoin (BTC) mining giant Bitmain for allegedly stealing $5.5 million worth of cryptocurrency from Bitmain’s account on Binance in April.
In the lawsuit filed with the U.S. District Court for the Western District of Washington at Seattle on Nov. 7, the court document revealed that an unknown hacker, referred to as “John Doe” in the case, managed to take over Bitmain’s Binance account and used stored Bitcoin to manipulate the price of altcoin Decentraland (MANA) and then steal the profits.
The document further revealed that the amount of Bitmain’s losses “exceeds” $5.5 million in “Bitcoin and other digital assets,” and specifying that the defendant was able to steal “approximately 617 BTC.” While adding that the document cites that the unauthorized action took place on April 22, when Bitcoin was trading at around $8,935.
The document also explains that as a part of the “scam,” the unknown hacker used two of their own accounts on now-second largest crypto exchange Binance, as well as on Bittrex, with around 2.3 million MANA already acquired on Bittrex.
“John Doe” reportedly placed purchase orders from Bitmain’s digital wallet offering to buy MANA “and other digital assets” with Bitmain’s bitcoins at a price that was “far above the going market rate.” The defendant also allegedly further artificially inflated MANA’s price by using Bitmain’s BTC to buy Ethereum (ETH), which was then used to buy MANA.
The hacker was said to have carried out a number of orchestrated trades in the reverse direction between BTC and MANA from Bitmain’s wallet and their own, eventually reportedly completing the theft by transferring BTC from their Bitmain account “ultimately into a digital wallet on the Bittrex cryptocurrency trading platform.”
It would br recalled that in October, Cointelegraph had reported that losses caused by hacks of crypto exchanges in the first nine months of 2018 exceeded that stolen in the whole of 2017 by 250 percent, with $927 million stolen.
