According to ME News, on October 30 (UTC+8), Israel’s State Prosecutor’s Office stated that Alexander Block (formerly Alexander Gurevich), suspected of stealing approximately $2.8 million in digital assets from the cross-chain bridge Nomad, was extradited to the United States on October 29. Block was arrested on May 2025 at Ben Gurion Airport while preparing to fly to Russia, shortly after changing his surname and obtaining a new passport under his new name.
Pursuant to the U.S. extradition request, Block discovered a vulnerability in Nomad that allowed bypassing verification of whether original assets were locked. After testing the vulnerability, Block withdrew approximately $2.8 million in tokens on August 1, 2022, without providing corresponding assets, subsequently exchanged them for other cryptocurrencies, and transferred funds across multiple wallets to obscure their origin. The U.S. District Court for the Northern District of California indicted Block in August 2023 on eight charges related to computer fraud, transportation of stolen property, and money laundering.
Israel's Supreme Court dismissed Block's appeal, ruling that exploiting a software vulnerability may still constitute illegal computer intrusion even if the software technically permits the related actions; it also determined that the public availability of blockchain transactions does not imply the ability to identify individuals behind wallets or rule out concealment of fund sources.
