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