The US 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.
TRON wallets have 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 in 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 linked to the group on the Tron, Monero and Bitcoin networks.
The freeze reinforces the role of centralized stablecoin issuers in enforcing sanctions. Tether froze more than $182 million worth of USDT in five Tron wallets in January under its sanctions compliance policy.
OFAC also sanctioned a network linked to Brazil and linked to the Primeiro Comando da Capital, or PCC, which the Treasury described as the largest criminal gang in Latin America.
According to the Treasury, the network laundered more than $30 million in illicit proceeds generated in the United States and used cryptocurrencies to move funds back to Brazil.
