2016 Bitfinex hack

The Bitfinex cryptocurrency exchange was hacked in August 2016.[1] 119,756 bitcoin, worth about US$72 million at the time, were stolen.[1]

In February 2022, the US government recovered and seized a portion of the stolen bitcoin, then worth US$3.6 billion,[2] by decrypting a file owned by Ilya Lichtenstein that contained addresses and private keys associated with the stolen funds.[3] Lichtenstein and his wife, Heather R. Morgan, were charged with conspiracy to launder the stolen bitcoin.[3] In August 2023, Lichtenstein admitted to committing the theft. Both Lichtenstein and Morgan pleaded guilty to money laundering.[4]

Hack

In August 2016, the Bitfinex cryptocurrency exchange, based in Hong Kong, announced it had suffered a security breach.[5] Around 2,000 approved transactions were sent to a single wallet from users' segregated wallets.[6][7] Immediately thereafter, Bitcoin's trading price plunged by 20%, causing the value of the stolen Bitcoin to dip to US$58 million.[1] After learning of the breach, Bitfinex halted all Bitcoin withdrawals and trading[8] and said it was tracking down the perpetrators of the hack.[7] Exchange customers, even those whose accounts had not been broken into, had their account balance reduced by 36% and received BFX tokens in proportion to their losses.[9] The exchange's access to U.S. dollar payments and withdrawals was then curtailed. The hack happened even though Bitfinex was securing the funds with BitGo, which uses multiple-signature security.[10]

In July 2023, Bitfinex worked with the Department of Homeland Security to recover about $315,000 in cash and cryptocurrencies stolen in the 2016 breach. The funds will be redistributed to holders of Bitfinex's Recovery Right Tokens, digital coins issued to people who suffered financial losses due to the hack.[11]

Laundering

Small amounts of money began to move out of the single wallet in early 2017 through the marketplace AlphaBay to launder it. After AlphaBay was shuttered by international law enforcement led by the FBI, the money was rerouted to the Russian marketplace Hydra. The shutdown of AlphaBay may have given law enforcement access to the service's internal transaction logs to connect pieces together.[6]

In February 2022, a New York couple, Ilya Lichtenstein (age 34) and his wife Heather R. Morgan (age 31),[6] were charged by US federal authorities with conspiring to launder the bitcoin, which was then worth US$3.6 billion.[2][12] Each of the pair faces a maximum sentence of 20 years in prison for conspiracy to launder money, and a maximum sentence of five years for conspiracy to defraud the United States.[12][13] Neither was charged with actually committing the hack.[14] Law enforcement were able to acquire a search warrant for a cloud storage service used by Lichtenstein, obtaining a spreadsheet of wallet addresses linked to the hack, and their passwords. One of the wallets had around 94,000 Bitcoin. Due to the openness and transparency of the blockchain, law enforcement was able to track the money; and obtaining the passwords allowed them to seize it.[6][15][16] They were charged in the case with a document known as an information, which is a type of charging document that federal prosecutors typically use when defendants have agreed to plead guilty.[17]

Some of the funds were moved towards more traditional financial accounts and used on gold, NFTs, and a Walmart gift card spent on Uber rides and a PlayStation.[18] Though hundreds of millions of dollars were converted to fiat currency, 80% of the Bitcoin were still in the original wallet at the center of the hack.[6]

Shortly after the couple's arrest, Netflix ordered a documentary series that will cover the story of Lichtenstein's and Morgan's crimes.[19]

In August 2023 both pleaded guilty. Lichtenstein additionally admitted carrying out the theft.[4]
