OFAC Updates ISIS-K Sanctions: 134 Crypto Addresses Listed
According to Chainalysis, the U.S. Treasury's Office of Foreign Assets Control (OFAC) updated its sanctions designation against the Islamic State's Khorasan Province (ISIS-K) on July 1, 2026. The update identified 134 cryptocurrency wallet addresses, including 131 TRON (Tron) addresses and 3 Monero addresses. This marks the first time OFAC has applied sanctions on a large scale to TRON-based addresses in connection with terrorism financing. The move underscores the U.S. government's expanding focus on non-Bitcoin blockchains in counter-terrorism efforts.
Tether Responds Quickly: Freezes Balances on All 131 Tron Addresses
Stablecoin issuer Tether acted in compliance with OFAC by freezing the balances of all 131 TRON wallet addresses. This is not the first time Tether has collaborated with law enforcement; the company has previously frozen wallets linked to illicit activities on Ethereum and TRON. Given that TRON hosts the largest circulation of USDT, this freeze directly impacts liquidity on the chain and highlights the growing AML (Anti-Money Laundering) compliance burden on stablecoin issuers. The action also serves as a precedent for future regulatory interventions on TRON-based assets.
Additional Sanctions: Brazilian PCC Network Involves $30 Million in Crypto Laundering
On the same day, OFAC separately sanctioned two Brazilian nationals and four companies. These individuals and entities are associated with the Latin American criminal organization Primeiro Comando da Capital (PCC). The network is accused of using cryptocurrencies to cross-border money laundering, with the total amount exceeding $30 million. PCC, Brazil's largest crime syndicate, has expanded from drug trafficking to crypto-enabled money movement. This sanctions package demonstrates OFAC's intensified focus on Latin America-based illicit finance, particularly the use of stablecoins and privacy coins.
ISIS-K Background: Terrorist Financing Threats in Central Asia
ISIS-K was first designated as a Specially Designated Global Terrorist (SDGT) entity by the U.S. in September 2015. The group operates primarily in Afghanistan, Pakistan, and several former Soviet republics in Central Asia. Historically, it has carried out attacks against civilians in numerous countries and has leveraged media outlets such as Al-Azaim Foundation to solicit cryptocurrency donations. The updated sanctions list indicates that the U.S. intends to tighten pressure on ISIS-K's on-chain funding channels, sending a clear compliance signal to exchanges, wallet providers, and stablecoin issuers globally.
