US sanctions crypto exchanges used by Russian darknet market, banks

The U.S. Treasury's OFAC sanctioned three crypto exchanges for enabling transactions with the Hydra darknet market and sanctioned Russian banks, describing Hydra as a large-scale darknet marketplace ( ~$1.35B turnover in 2020) that offered drugs, money laundering, stolen databases, forged documents, and hacking-for-hire; sanctions freeze U.S. assets and target entities facilitating sanctions evasion.
