Alexander Block, an Israeli-Russian citizen accused of exploiting a vulnerability in the Nomad cross-chain bridge to steal $2.8 million in digital assets, was extradited from Israel to the United States on Oct. 29 after losing his legal challenge. U.S. prosecutors allege that Block used a flaw in Nomad’s automated system to withdraw tokens without depositing the corresponding backing assets, then converted them into other cryptocurrencies and moved them between wallets to conceal their origin. He faces eight counts in the Northern District of California involving computer offenses, transferring stolen property and money laundering. Israel’s Supreme Court ruled that exploiting a programming vulnerability may constitute unlawful computer intrusion even when software permits the transactions, and that publicly visible blockchain transfers do not rule out money laundering because wallet controllers may remain unidentified. The case adds a significant cross-border enforcement precedent for crypto-related offenses.
