Israeli-Russian Dual Citizen Extradited to US for Crypto Fraud

Alexander Blok (Gurvitz), an Israeli-Russian dual citizen, was extradited from Israel to the United States on Wednesday to face charges of fraud, computer-related offenses, trafficking in stolen property, and money laundering totaling millions of dollars. Blok was arrested at Ben Gurion Airport in May of last year while en route to Russia, following an extradition request from U.S. authorities.

According to the U.S. extradition request, Blok is suspected of exploiting a security vulnerability in the "Nomad" system, which is used for converting cryptocurrency between different blockchain networks. On August 1, 2022, Blok allegedly altered the system's code to issue him digital tokens worth approximately $2.8 million without depositing any actual funds. He then converted these tokens to various cryptocurrencies and transferred them between digital wallets to obscure their origin.

During the legal proceedings in Israel, the District Court declared Blok eligible for extradition. His appeal to the Supreme Court was rejected, establishing a precedent that the term "computer material intrusion" also applies to exploiting security flaws and programming errors. The court further ruled that the public nature of blockchain networks does not negate money laundering charges, as wallet ownership remains anonymous and such transfers complicate fund tracing.

After his petition for a rehearing before the President of the Supreme Court was also denied, all legal avenues in Israel were exhausted, and Blok was handed over to U.S. authorities.
