Bio
Alexander Gurevich, a dual Russian-Israeli citizen, is named by U.S. prosecutors as the first person to exploit a critical flaw in the Nomad token bridge on August 1, 2022, withdrawing about $2.89 million in tokens. His exploit was rapidly copied by hundreds of others, draining nearly all of Nomad's ~$190 million. Days later he allegedly contacted Nomad's CTO on Telegram under a false name, apologized, returned a small portion, and sought a "reward." [1][2]
Status
A federal grand jury in the Northern District of California indicted Gurevich on eight counts (including computer fraud and money laundering) on August 16, 2023. He was arrested at Israel's Ben-Gurion Airport on May 1, 2025 while attempting to fly to Russia after legally changing his name to "Alexander Block"; Israeli courts approved his extradition to the U.S. [1][2]
