According to the indictment, Nashatka conspired with others in December of 2017 to target EtherDelta to obtain the private keys and other information of hundreds of its users as part of a scheme to steal the users’ cryptocurrency.

The indictment further described how Nashatka and his co-conspirators unlawfully used the identity of a victim to gain access to the platform’s domain name settings, caused the transmission of a command to divert users from the actual platform to a fake website, and fraudulently induced victims to input their cryptocurrency addresses and private keys into the fake website.

Between December 20 and 21, 2017, Nashatka and his co-conspirators logged the credentials of hundreds of victims, stole their cryptocurrency, and transferred approximately $600,000 in cryptocurrency to one cryptocurrency address controlled by Nashatka and his co-conspirators.
