Elizabeth Rosenberg, a senior official of the U.S. Treasury Department, said that the U.S. Treasury Department has reviewed the role of decentralized finance (DeFi) in incidents such as the North Korean ransomware attack, and will soon release a risk assessment to analyze the criminal use of DeFi. Elizabeth Rosenberg said, “Illegal actors are always looking for effective ways to hide criminal activities and launder their proceeds, which poses a threat to DeFi services or other elements of the virtual asset ecosystem. The team is actively working on an assessment that will be released soon. "
