Alexander Blok, a dual Israeli-Russian citizen, has been extradited to the United States to face charges of fraud, computer intrusion, trafficking in stolen property, and money laundering. Blok was apprehended at Ben Gurion Airport in May 2025 as he attempted to depart for Russia. According to the U.S. extradition request, in the summer of 2022, Blok identified a vulnerability in the "Nomad" crypto system, used for converting currencies between blockchain networks. Prosecutors allege he altered the system's code to issue him digital currency representations without depositing equivalent value. He then allegedly withdrew tokens worth approximately $2.8 million, which he converted and transferred across various wallets to obscure the funds' origin.
The extradition was a collaborative effort involving the Israel Police, Interpol, and the Operational Coordination Unit, following the exhaustion of all appeal processes in Israel. The Israeli Supreme Court rejected Blok's final appeal, establishing a legal precedent. The court ruled that exploiting security flaws and programming errors constitutes illegal computer intrusion. Furthermore, it was determined that the public nature of a blockchain network does not preclude money laundering charges, as the anonymity of wallet holders complicates the tracing of funds and perpetrators. The extradition case was managed by attorney Avi Kronenberg from the State Attorney's Office International Department.
