AI-Driven Deepfake BEC Scheme Charges Three in $129 Million Fraud

Three individuals were indicted in the Southern District of New York for an AI-augmented business email compromise (BEC) scheme that caused approximately $129 million in losses. Attackers used AI voice cloning, deepfake video generation, and spoofed corporate email accounts to impersonate CEOs and attorneys, authorizing fraudulent wire transfers via VoIP and video conferencing. The campaign represents a shift from text-based BEC to multimodal synthetic identity fraud, exposing gaps in financial authorization and voice/video verification controls.
