Besides the arrests, federal law enforcement officials also revealed that the Justice Department has seized roughly $3.6 billion in cryptocurrency linked to the hack of Bitfinex, a virtual currency exchange whose systems were breached nearly six years ago.
The stolen cryptocurrency, valued at $71 million at the time of the theft, is now valued at $4.5 billion, officials said.
Ilya Lichtenstein and his wife, Heather Morgan, were arrested in Manhattan on Tuesday morning and face federal charges of conspiracy to commit money laundering and conspiracy to defraud the United States. It was unclear if they had lawyers or people who could speak on their behalf.
Prosecutors say Lichtenstein and Morgan relied on a series of sophisticated techniques to receive stolen bitcoin into a digital wallet they controlled and to conceal the transactions and hide the movement of the money. Millions of dollars of the transactions were cashed out through bitcoin ATMs and to purchase gold and non-fungible tokens as well as more mundane items like Walmart gift cards used for personal expenses, prosecutors said.
The couple were not charged in the Bitfinex hack, which resulted in more than 2,000 unauthorized transactions.
Justice Department officials say that though the proliferation of cryptocurrency and virtual currency exchanges represent innovation, the trend has also been accompanied by money laundering, ransomware and other crimes
“Today’s arrests, and the Department’s largest financial seizure ever, show that cryptocurrency is not a safe haven for criminals,” Deputy Attorney General Lisa Monaco said in a statement. “In a futile effort to maintain digital anonymity, the defendants laundered stolen funds through a labyrinth of cryptocurrency transactions. Thanks to the meticulous work of law enforcement, the department once again showed how it can and will follow the money, no matter the form it takes.”
