The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) has sanctioned Russian national Ekaterina Zhdanova for laundering millions in cryptocurrency for various individuals, including ransomware actors.

Zhdanova used her expertise in cryptocurrency and blockchain networks to move money through various platforms such as Garantex (sanctioned in April 2022 for aiding the Hydra Market) to evade “Anti-Money Laundering/Combating the Financing of Terrorism” (AML/CFT) controls.
