Ilya Lichtenstein was sentenced today to five years in prison for his involvement in a money laundering conspiracy arising from the hack and theft of approximately 120,000 bitcoin from Bitfinex, a global cryptocurrency exchange.

According to court documents, Lichtenstein, 35, hacked into Bitfinex’s network in 2016, using advanced hacking tools and techniques. Once inside the network, Lichtenstein fraudulently authorized more than 2,000 transactions transferring 119,754 bitcoin from Bitfinex to a cryptocurrency wallet in Lichtenstein’s control. Lichtenstein then took steps to cover his tracks by deleting from Bitfinex’s network access credentials and other log files that could have revealed his conduct to law enforcement. Following the hack, Lichtenstein enlisted the help of his wife, Heather Morgan, in laundering the stolen funds.
