The U.S. Treasury Department has intensified its efforts to cut off terrorist financing by sanctioning 134 cryptocurrency wallet addresses linked to ISIS-K, while stablecoin issuer Tether said it has frozen funds held in 131 of those wallets.
The sanctions were imposed by the Treasury’s Office of Foreign Assets Control (OFAC), which oversees U.S. economic and trade sanctions.
The move bars U.S. individuals and companies from conducting transactions involving the listed wallet addresses and aims to disrupt the group’s ability to move money through digital assets.
ISIS-K, or the Islamic State Khorasan Province, is an affiliate of the Islamic State that operates primarily in Afghanistan and surrounding regions. The group has been linked to numerous attacks and has long been designated as a terrorist organization by the United States.
Treasury says wallets helped facilitate ISIS-K’s financial operations
According to the Treasury, the newly sanctioned crypto wallets were connected to ISIS-K’s financial network and were allegedly used to receive, store or transfer funds that supported the group’s activities.
Soon after the sanctions were announced, Tether confirmed that it had frozen assets associated with 131 of the listed wallet addresses.
The company said the action was taken in line with its compliance policies and ongoing cooperation with law enforcement agencies around the world.
The latest move highlights how governments and private crypto companies are increasingly working together to prevent digital assets from being used to finance terrorism and other illegal activities.
Although cryptocurrencies are often associated with anonymity, most blockchain transactions are permanently recorded on public ledgers. That allows investigators and blockchain analytics firms to trace transactions and identify wallets linked to criminal organizations.
Stablecoin issuers such as Tether can also freeze tokens under their control when wallets are tied to sanctions or law enforcement investigations.
OFAC continues expanding crypto sanctions against illicit actors
In recent years, OFAC has repeatedly targeted cryptocurrency wallets connected to ransomware groups, sanctioned governments, cybercriminals and terrorist organizations as part of its broader enforcement strategy.
At the same time, crypto companies have invested heavily in compliance systems that monitor blockchain activity and block transactions involving sanctioned entities.
Tether has become one of the most active companies in this area.
The stablecoin issuer has frozen hundreds of millions of dollars in digital assets over the past several years while working with agencies including the U.S. Department of Justice, the Federal Bureau of Investigation (FBI) and international law enforcement authorities.
The latest sanctions also reflect growing attention on the role digital assets can play in illicit finance.
Officials have acknowledged that terrorist groups continue to experiment with cryptocurrencies to move money across borders, even though traditional financial networks still account for the vast majority of terrorist financing globally.
As the crypto industry continues to mature, regulators are placing greater emphasis on monitoring blockchain transactions and strengthening cooperation with digital asset companies.
By sanctioning the wallets and quickly freezing associated funds, U.S. authorities and Tether hope to make it harder for ISIS-K to access or move money through cryptocurrency networks.
The action underscores a broader trend in the crypto industry, where blockchain transparency and collaboration between regulators and private companies are becoming increasingly important tools in the fight against financial crime and terrorist financing.
