The U.S. Treasury Department designated the A7 Network as a significant transnational criminal organization and proposed prohibiting U.S. financial institutions from sending or receiving funds, including cryptocurrency, involving its Sub-Agents. The measures, announced Oct. 1 under Operation Economic Outcast, combine an OFAC designation with a FinCEN notice of proposed rulemaking and alert on suspicious activity. Treasury describes A7 as a Russian-linked shadow-banking system used by Iran to evade sanctions through third-country companies, trade documents, crypto settlement channels and conventional accounts. The network is led by Ilan Mironovich Shor and uses purpose-built Sub-Agents to make illicit payments appear commercial. FinCEN found that the Sub-Agents processed more than $17 billion between January 2025 and June 2026, while A7 claimed daily volume above 7.5 trillion rubles, or about $91.5 billion, as of January 2026. Treasury also linked A7 to the A7A5 ruble-backed token, Nobitex, North Korean cryptocurrency-exchange hacks and ransomware actors. A7 property within U.S. jurisdiction is blocked, and the proposed rule's public-comment period would close 30 days after publication in the Federal Register.
