Summary
- OFAC sanctioned 134 crypto addresses linked to ISIS-K (131 Tron, 3 Monero) on Wednesday, and Tether subsequently froze the funds in all 131 Tron wallets.
- ISIS-K used its media wing to solicit donations via Tron, Monero, and Bitcoin, highlighting stablecoin issuers' growing role in sanctions, Chainalysis said.
- The Treasury also sanctioned a Brazil-linked network tied to the criminal gang PCC, which laundered over $30 million in illicit funds using crypto.
The U.S. Treasury's Office of Foreign Assets Control (OFAC) added 134 crypto wallet addresses to its ISIS-Khorasan (ISIS-K) sanctions entry on Wednesday, including 131 Tron addresses and 3 Monero addresses.
The TRON wallets received more than $1.4 million since 2023 and sent more than $880,000, according to Chainalysis. Tether froze balances on all 131 Tron addresses.
ISIS-K, the Islamic State affiliate active across Afghanistan, Pakistan and parts of Central Asia, has used its media arm al-Azaim Media Foundation to solicit crypto donations through websites and messaging platforms, Chainalysis said.
Chainalysis said it identified historical donation addresses tied to the group on the Tron, Monero and Bitcoin networks.
The freeze reinforces the role of centralized stablecoin issuers in sanctions enforcement. Tether froze more than $182 million in USDT across five Tron wallets in January under its sanctions compliance policy.
OFAC also sanctioned a Brazil-linked network tied to Primeiro Comando da Capital, or PCC, which Treasury described as Latin America's largest criminal gang.
The network laundered more than $30 million in U.S.-generated illicit proceeds and used crypto to move funds back to Brazil, according to the Treasury.
