Ilya Lichtenstein, the hacker behind the 2016 Bitfinex exchange breach, has been sentenced to five years in prison for his role in one of the largest cryptocurrency thefts in history. He stole approximately 120,000 Bitcoin, valued at $71.8 million at the time, which is now worth over $8 billion.
Lichtenstein exploited vulnerabilities in Bitfinex's system and deleted crucial access logs and credentials to cover his tracks. He authorized over 2,000 transactions transferring 119,754 Bitcoins to a wallet under his control.
After the hack, Lichtenstein enlisted his wife, Heather Morgan, to help with money laundering techniques, including using fictitious identities, automating transactions, and converting bitcoin into other cryptocurrencies.
Both Lichtenstein and Morgan pleaded guilty to conspiracy to commit money laundering. Lichtenstein received a five-year sentence, while Morgan is scheduled for sentencing on November 18, 2024.
