U.S. authorities have seized more than $560,000 in cryptocurrency tied to Hamas fundraising campaigns and taken control of websites and servers used to solicit donations and communicate with supporters.

The operation combined the court-authorized cryptocurrency seizures with infrastructure actions spanning March 2025 through August 2026. Three cryptocurrency seizure warrants were executed in March, June, and October 2025, followed by additional operations against online infrastructure in July and August of this year. Hamas has been designated a foreign terrorist organization by the United States since 1997, and its military wing, the Al-Qassam Brigades, has been subject to U.S. sanctions designations, making any material support for the group a federal crime.

FBI Traced Donations Across Wallets and Bridges

Hamas supporters were directed through encrypted communications to fundraising websites that supplied rotating cryptocurrency donation addresses for the Al-Qassam Brigades.

The first action, in March 2025, recovered approximately $200,000 in stablecoins. Investigators subsequently linked additional addresses through recurring transaction infrastructure, including a shared gas-funding wallet used across multiple addresses associated with the fundraising network.

Later transactions moved through new wallets, centralized exchanges, and cross-chain bridges. The network also included an account believed to be connected to a Lebanon-based over-the-counter broker and another exhibiting activity consistent with a money mule.

By October 2025, the fundraising operation had begun using single-use donation addresses and cross-chain bridges as funds moved between blockchains. Transaction histories still allowed investigators to connect new addresses with previously identified operational and consolidation wallets.

FBI Takes Control of Hamas Websites and Servers

The investigation expanded beyond cryptocurrency in 2026. FBI agents seized domains and servers associated with AlQassam.ps, the main website used by Hamas' military wing, through enforcement actions in July and August.

Control of the infrastructure enabled investigators to intercept intended donations and collect information on thousands of individuals who contacted Hamas online seeking to donate or attempting to contribute through cryptocurrency and conventional payment methods.

Hamas-linked crypto wallets have also faced seizures outside the United States. Israeli authorities previously confiscated 30 Hamas-linked wallets associated with accounts tied to the Gaza-based Al-Mutahadun exchange.

Blockchain Tracking Builds Across Five Enforcement Actions

The five U.S. actions demonstrate how previously identified blockchain infrastructure can remain useful even after a fundraising network changes addresses or moves funds between chains.

Public ledgers preserve transaction histories across those movements, allowing wallet clusters, bridge transfers, and exchange deposits to be revisited as investigators identify additional addresses. Crypto seizures, freezes, and recoveries reached an estimated 11% of identified illicit volume during 2025 as issuers, exchanges, and law-enforcement agencies expanded blockchain tracing and asset-recovery operations.

The FBI's Albuquerque Field Office continues the Hamas financing investigation together with its Counterterrorism Division, Cyber Division, and New York Field Office. Information obtained from the seized infrastructure will be used in further counterterrorism investigations involving individuals who attempted to send funds to the organization, a signal that the seized donor records themselves may feed future cases.
