A married couple from New York City pleaded guilty today to money laundering conspiracies arising from the hack and theft of approximately 120,000 bitcoin from Bitfinex, a global cryptocurrency exchange.
Ilya Lichtenstein, 35, and Heather Morgan, 33, were arrested in February 2022 after the government seized approximately 95,000 of those stolen bitcoin from cryptocurrency wallets in the defendants’ control. At the time of the seizure, the recovered funds were valued at approximately $3.6 billion. Since their arrests, the government has seized another approximately $475 million tied to the hack.
According to court documents, Lichtenstein used a number of advanced hacking tools and techniques to gain access to Bitfinex’s network. Once inside their systems, Lichtenstein fraudulently authorized more than 2,000 transactions in which 119,754 bitcoin was transferred from Bitfinex to a cryptocurrency wallet in Lichtenstein’s control. Lichtenstein then took steps to cover his tracks by going back into Bitfinex’s network and deleting access credentials and other log files that may have given him away to law enforcement. Following the hack, Lichtenstein enlisted the help of his wife, Morgan, in laundering the stolen funds.
Lichtenstein, at times with Morgan’s assistance, employed numerous sophisticated laundering techniques, including using fictitious identities to set up online accounts; utilizing computer programs to automate transactions; depositing the stolen funds into accounts at a variety of darknet markets and cryptocurrency exchanges and then withdrawing the funds, which obfuscates the trail of the transaction history by breaking up the fund flow; converting bitcoin to other forms of cryptocurrency, including anonymity-enhanced cryptocurrency (AEC), in a practice known as “chain hopping”; depositing a portion of the criminal proceeds into cryptocurrency mixing services, such as Bitcoin Fog, Helix, and ChipMixer; using U.S.-based business accounts to legitimize their banking activity; and exchanging a portion of the stolen funds into gold coins, which Morgan then concealed by burying them.
Lichtenstein pleaded guilty to conspiracy to commit money laundering, which carries a maximum penalty of 20 years in prison. Morgan pleaded guilty to one count of money laundering conspiracy and one count of conspiracy to defraud the United States, each of which carries a maximum penalty of five years of in prison. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.
Consistent with standard practice in criminal forfeiture cases, there will be a formal process at the conclusion of the case pursuant to Rule 32.2 of the Federal Rules of Criminal Procedure for third-party claimants to submit claims for any seized and forfeited property.
