Bitfinex

In August 2016, Bitfinex, a cryptocurrency exchange, experienced a substantial security breach resulting in the loss of around 120,000 bitcoin, valued at about $71 million at the time. The stolen amount later inflated to a staggering $4.5 billion due to cryptocurrency value increases. Ilya Lichtenstein and Heather Morgan were arrested for the hack and for laundering the proceeds. After guilty pleas, Lichtenstein received a five-year sentence, and law enforcement recovered assets exceeding $10 billion, including cryptocurrency spikes and additional seizures related to the hack. This event highlights the significant risks and financial implications associated with security vulnerabilities and cybercrime within the digital currency space.
