When the Justice Department selected Eun Young Choi to lead its new National Cryptocurrency Enforcement Team last week, DOJ officials chose a prosecutor who has been at the forefront of prosecuting cybercrime as it has developed and evolved in recent years.

Choi began her career as a federal prosecutor in 2012 in the Southern District of New York, an office known for its aggressive financial crimes prosecutions. Choi led several high-profile fraud cases and eventually became the SDNY’s cybercrime coordinator.
