Last month, blockchain analytics firm Elliptic reported that North Korean hackers had stolen more than $2 billion worth of cryptocurrency in 2025, underscoring the regime’s growing reliance on digital assets.
According to Treasury, DPRK-linked hackers use advanced malware, phishing campaigns, and social engineering to breach crypto firms and exchanges. A recent CoinDesk investigation also found that North Korean hackers are increasingly leveraging AI to automate and scale their attacks.
The sanctioned network allegedly relied on cryptocurrency transactions and shell companies to conceal the flow of illicit funds. Two North Korean bankers, Jang Kuk Chol and Ho Jong Son, managed at least $5.3 million in crypto tied to OFAC-designated First Credit Bank, funds linked to a ransomware group that previously targeted U.S. victims and laundered earnings from overseas DPRK IT workers.
OFAC said both men were designated under multiple executive orders for supporting cyber-enabled activities and commercial operations that generate revenue for the North Korean government.
The Treasury also targeted Korea Mangyongdae Computer Technology Company (KMCTC), which operates IT worker delegations in China’s Shenyang and Dandong. KMCTC and its president, U Yong Su, allegedly used Chinese nationals as banking proxies to disguise the origins of funds earned by DPRK IT workers abroad.
Tuesday’s actions extend to Ryujong Credit Bank, accused of facilitating international transfers for North Korean entities involved in sanctions evasion and crypto laundering.
OFAC said the designations reinforce U.S. efforts to “cut off illicit revenue streams” fueling North Korea’s weapons programs and cyber operations that threaten the global digital economy.
