Israel Extradites Nomad Bridge Hacker Alexander Block to U.S. After Court Ruling
Current overview (not historical)
Israel’s Supreme Court rejected Alexander Block’s appeal, affirming that exploiting a programming flaw constitutes illegal computer intrusion. Block, accused of stealing roughly $2.8 million in 2022 by exploiting a vulnerability in the Nomad Bridge, was extradited to the United States in October 2026. The flaw later enabled other users to siphon $186 million from the platform. The U.S. requested extradition in December 2024, and after Block’s appeal was dismissed, he was transferred to U.S. jurisdiction for trial. The case underscores the growing legal scrutiny of software vulnerabilities and their potential for large‑scale theft. It also highlights the cooperation between Israeli and U.S. authorities in prosecuting cyber‑crime across borders.

Report first recorded Oct 30, 21:07
Israel has extradited Alexander Block (formerly Alexander Gurevich), an Israeli‑Russian citizen, to the United States to face federal charges for allegedly stealing about $2.8 million from the crypto bridge Nomad in August 2022. Block used a June 2022 software update flaw that allowed users to receive tokens on one blockchain without locking the equivalent assets on another. After six test transfers, he conducted four main transfers, moving the stolen tokens through multiple wallets and converting them to other cryptocurrencies. His actions exposed the flaw to other users, who subsequently drained a Nomad‑controlled wallet holding more than $186 million in user funds. Israel’s Supreme Court rejected Block’s appeal, ruling that exploiting a programming flaw can constitute unlawful computer intrusion even when the software permits the action. The U.S. federal grand jury indicted Block in August 2023 on four counts of computer fraud, one count of transporting stolen property, and three counts of money laundering.
