A copy-paste error led to a nearly $50 million USDT loss due to an address poisoning scam. Scammers used a spoofed address for a small transaction to deceive the victim into copying it, facilitating rapid theft and laundering.
A cryptocurrency user lost $50 million USDT on Ethereum on December 20, 2025, due to an address poisoning scam where funds were converted and laundered via Tornado Cash.

The crypto user fell victim to an address poisoning scam, an increasingly common tactic. Scammers use look-alike addresses to trick victims into transferring significant sums to fraudulent accounts on Ethereum.
An unknown user mistakenly transferred 49,999,950 USDT to a spoofed address. Scammers promptly converted these funds to ETH and utilized Tornado Cash for laundering.
