Ilya Lichtenstein has been sentenced to five years in prison for orchestrating the 2016 theft of over 119,000 bitcoin from the Bitfinex cryptocurrency exchange, a crime that has been described as one of the largest cyber thefts in history. His wife, Heather Morgan, who used the alias 'Razzlekhan' for her music career, was also involved in laundering the stolen funds and will be sentenced on November 18. The stolen bitcoin was worth about $71 million at the time of the theft but surged to over $4.5 billion by the time of the couple's arrest in 2022. Lichtenstein used advanced hacking tools to carry out the theft and employed complex laundering techniques including darknet markets and cryptocurrency mixers to conceal the origins of the funds. Despite their efforts, authorities managed to recover a significant portion of the stolen assets, marking the largest financial seizure in the U.S. Department of Justice's history. Lichtenstein expressed remorse for his actions and hopes to apply his skills to combat cybercrime in the future.
