A recent incident has highlighted a dangerous threat in the crypto space: address poisoning scams targeting USDT transactions. One user fell victim to this sophisticated attack, losing over half a million dollars in a single transaction. Here's what happened and why it matters. Address poisoning works by flooding a user's transaction history with transactions from lookalike addresses—so close to legitimate ones that they're easy to miss at a glance. When victims copy what they believe is the correct address, they actually send funds to the scammer's wallet instead. The financial impact can be devastating, especially for large transfers. This incident serves as a critical reminder: always verify addresses through official channels, double-check before confirming any transaction, and consider using address books or whitelisting features on your exchange or wallet. In a space where transactions are irreversible, these few seconds of extra caution can mean the difference between security and catastrophic loss.
