In 2016, Ilya Lichtenstein stole 120,000 BTC from Bitfinex, worth billions today, in one of the largest cryptocurrency hacks in history.
Lichtenstein used advanced hacking tools to authorize over 2,000 fraudulent transactions and erase crucial access logs, making tracking nearly impossible.
The couple laundered 25,111 BTC (21%) using Eastern European accounts, cryptocurrency mixers, darknet markets, and even converted BTC into gold.
Rookie mistakes, like linking accounts to personal identities, exposed their operation. Lichtenstein accidentally revealed himself as the hacker.
Lichtenstein received 5 years in prison, while his wife Heather Morgan, known as "Razzlekhan," faces an 18-month sentence for her role.
The case highlights cybercrime risks, evolving law enforcement techniques, and the need for stronger crypto security measures.
