An accomplished former federal prosecutor, Eun Young Choi brings more than a dozen years of experience as a federal prosecutor and leader in the U.S. Department of Justice (DOJ), advising clients on a wide range of white collar and national security matters. Eun Young held senior positions across the DOJ, where she served as a leader in its efforts to address a wide range of technology-based risks to public safety and national security, and regularly represented the DOJ in high-level interagency, international, and public engagements. Drawing on these experiences, Eun Young counsels clients on key areas such as cybersecurity, cryptocurrency, artificial intelligence, and other emerging technologies, along with internal and government investigations and related complex and sensitive areas.
Most recently, Eun Young served as Deputy Assistant Attorney General for National Asset Protection in the National Security Division, where she oversaw the creation of the National Security Cyber Section, which spearheads the DOJ’s efforts to disrupt and respond to malicious cyber activity posed by nation-state adversaries; supervised and shaped the DOJ’s criminal enforcement programs for sanctions, export controls, economic espionage, and foreign malign influence, including corporate enforcement actions related to national security laws and authorities; and led the DOJ’s review of foreign investment, data security, and emerging technology risks to national security, supervising over 120 attorneys and staff.
Eun Young previously served as the inaugural Director of the National Cryptocurrency Enforcement Team, leading a team of over 20 experts drawn from across the DOJ, the FBI, and the SEC, charged with serving as the DOJ’s focal point in its efforts to combat the criminal misuse of digital assets. In that role, Eun Young managed and supervised investigations involving cutting-edge exploitation of digital asset technologies and platforms and exchanges that facilitated the criminal use of digital assets. She also served as Senior Counsel to the Deputy Attorney General, where she was responsible for coordinating the DOJ’s response to ransomware and other significant attacks against critical infrastructure, and advising the DOJ’s senior leadership on strategy for cyber and emerging technology-related issues.
