A fraudster once weaponized a simple tactic: fake invoicing at scale. He submitted $100 million in fabricated invoices to Google and Facebook across various expense categories. The result? Nearly all payments went through without proper verification.

How did two tech giants—with sophisticated financial teams—process such massive fraudulent claims? The case reveals critical gaps in corporate invoice validation systems, even at the industry's largest players. The attacker exploited administrative friction and trust defaults in the payment pipeline.

He's currently serving time for wire fraud. This case is a hard reminder: scale doesn't guarantee security. Even Fortune 500 companies can fall victim to well-executed schemes when payment controls aren't bulletproof. For crypto and fintech builders, the lesson is stark—multi-signature verification, spend limits, and transaction auditing aren't luxuries; they're non-negotiable.
