Israel Extradites Nomad Suspect After Supreme Court Rejected His Code-Bug Defense
He is accused of helping trigger a breach that drained nearly $190 million and of laundering about $2.8 million in stolen tokens, prosecutors said.
- On Thursday, Israel extradited Alexander Block to the United States to face charges over the alleged theft of approximately $2.8 million in digital assets from the cryptocurrency platform Nomad.
- Investigators allege that Block, born Alexander Gurevich, exploited a security vulnerability in August 2022 to withdraw tokens without providing the corresponding assets required by the Nomad system.
- Research by cryptocurrency exchange Coinbase found that nearly $190 million was stolen in the breach overall, with approximately 88% of involved addresses belonging to "copycats" who collectively stole about $88 million.
- In May 2025, authorities arrested Block at Ben Gurion Airport while he prepared to travel to Russia, following his unsuccessful legal challenges against extradition.
- Facing an eight-count indictment in the Northern District of California, he could face up to 20 years in prison if convicted of computer fraud and money laundering charges.
