Two brothers who studied at the Massachusetts Institute of Technology were arrested on Wednesday on U.S. charges that they carried out a cutting-edge scheme to exploit the Ethereum blockchain's integrity and steal $25 million worth of cryptocurrency. Federal prosecutors in Manhattan called the scheme perpetrated by Anton Peraire-Bueno, 24, and James Peraire-Bueno, 28, "novel" and said the case marked the first time that such a fraud had ever been the subject of U.S. criminal charges. Authorities said they executed their elaborate heist in April 2023, stealing $25 million from traders in just 12 seconds by fraudulently gaining access to pending transactions and altering the movement of cryptocurrency.
