U.S. Department of the Treasury's Office of Foreign Assets Control said that cybercriminals regularly used Tornado Cash to launder money amounting to more than US$7 billion since 2019.
Tornado Cash is a digital currency mixer that obfuscates transaction history by combining ETH deposits from many users into one pool before paying out Ethereum withdrawals.
U.S. authorities are reportedly investigating Kraken due to suspicions that the controversial digital currency exchange has violated economic sanctions against Iran.
The Justice department’s complaint involves a U.S. citizen accused of transmitting more than $10 million worth of BTC to a digital currency exchange in a country under sanctions from the United States.
The body is on the lookout for “one to two tools that provide access to five (5) users each, either as individual licenses or one concurrent license.”
