In a whirlwind of digital chaos, the Nomad cross-chain bridge suffered a $190 million plunder in August 2022, an event that transformed a single exploit into a wild, free-for-all attack.
The Heist
- The Mastermind: Alexander Gurevich, a man holding both Israeli and Russian citizenship, is suspected to be the culprit who unearthed and capitalized on a glaring weakness in Nomad's code. Gurevich, operating under the alias "Alexander Block," made off with a substantial $2.89 million haul following the breach [1][3][4].
- The Perfect Storm: The vulnerability propelled a chain reaction, enabling attackers to assume mastery over Nomad's smart contracts by broadcasting invalid transactions. This simple maneuver allowed them to reclaim funds without being double-checked [5].
- The Copycat Conundrum: Data analysis conducted by Coinbase's blockchain investigation team revealed that a horde of 88 addresses joined in on the frenzy, scrambling to collectively swipe $88 million [1][5].
The Aftermath
- Good Samaritans: Some of the addresses found in the chaos turned out to be "whitehats," or ethical hackers, who voluntarily returned the funds they had flabbergastedly withdrawn [1][5].
- Gurevich Post-Exploit Capers: After pilfering the funds, Gurevich adopted a phony identity to engage with Nomad's CTO, James Prestwich, proposing a partial refund in exchange for a $500,000 bounty [4]. However, the negotiations dissolved, leaving him in the wind.
- Criminal Charges: US prosecutors in California handed down an eight-count indictment against Gurevich in August 2023, implicating him in numerous federal charges, including laundering money, wire fraud, and computer-related offenses [4]. An official extradition request was submitted in December 2024, and Gurevich was apprehended in Israel in May 2025, awaiting transportation to the United States [2][3][5].
- Execrable Consequence: If extradited and found guilty, Gurevich stands to serve up to 20 years in prison solely for money laundering-related charges [4]. The event serves as a stark reminder of the intricate web of consequences hackers can face in the crypto realm.
