U.S. authorities recovered approximately $560,000 in cryptocurrency intended for Hamas and its military wing, the Al-Qassam Brigades, through three seizure warrants executed in 2025. The FBI later seized domains and servers, including AlQassam.ps, under warrants dated July 29 and August 18, 2026, disrupting fundraising and recruitment channels. Investigators combined confidential human sources with blockchain analysis to track rotating wallet addresses promoted through encrypted chats and websites. The network moved more than $1.5 million by the time of the first major seizure, while later estimates put total donations above $3 million by November 2025. Assets included Bitcoin, Ethereum, Wrapped Ethereum, Tether and Tron, with USDT on Tron appearing frequently. The operation also produced information on thousands of people who contacted Hamas-linked platforms using cryptocurrency or traditional payment methods, supporting future counterterrorism investigations.
