OFAC Lists 134 ISIS-K Wallets, Tether Freezes 131 — Tron Terror Donations Total $1.4M 🧊

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) added 134 cryptocurrency wallet addresses to its Specially Designated Nationals (SDN) list on Wednesday, designating them as property of ISIS-Khorasan (ISIS-K), a Specially Designated Global Terrorist since September 2015. Stablecoin issuer Tether has frozen balances on all 131 sanctioned Tron ($TRX) addresses, with the remaining three addresses residing on the Monero ($XMR) network, according to blockchain analytics firm Chainalysis. ISIS-K operates across Afghanistan, Pakistan, and parts of Central Asia.

Chainalysis reported that the 131 designated Tron addresses received more than $1.4 million in crypto donations since 2023 and sent over $880,000 during that period. The group historically solicited donations through campaigns on websites and messaging platforms, primarily via its media arm, the al-Azaim Media Foundation, with individual contributions tending to be small in size. Several of the newly sanctioned wallets transmitted funds to Syria-based cryptocurrency exchanges, and Chainalysis found significant exposure to mainstream services across the broader cluster.

"Chainalysis has collected historical donation addresses on Tron, Monero, and Bitcoin," the analytics firm stated. The July 1 action follows a June 22 OFAC move that sanctioned three individuals and six entities, including Syria-based MSB Bitcoin Xchange and Turkish MSB Spider, targeting what OFAC described as "key facilitators who enable ISIS to move funds among its regional affiliates." Earlier in 2023, OFAC designated Maldives-based operative Ali Shafiu, whose Tron wallet interacted with deposit addresses tied to Iranian exchanges.

Tether's enforcement aligns with a broader industry pattern. The company's T3 Financial Crime Unit, operated jointly with Tron and TRM Labs, has frozen more than $450 million in illicit crypto since launching in September 2024. In a separate Wednesday action, OFAC sanctioned two Brazilian nationals and four companies tied to the Primeiro Comando da Capital (PCC), alleging they used crypto to launder more than $30 million in U.S. drug trafficking proceeds back to Brazil. Blockchain analytics tools continue to play a growing evidentiary role, with TRM Labs noting earlier in April that onchain data anchored terrorism financing prosecutions in Indonesian courts during 2024 and 2025.
