In a recent crypto scam, a once wealthy Ethereum user lost $68 million in Bitcoin holdings due to an address poisoning attack. The victim was tricked into sending 1155 Wrapped Bitcoin (WBTC), a token that mirrors Bitcoin's price on the Ethereum network, to a malicious wallet. Address poisoning involves attackers sending a transaction of negligible value to a victim's wallet, making their address appear in the victim's transaction history. The attackers' address often has several starting and ending characters matching the victim's, making it difficult to detect the deception. This incident highlights the vulnerability of WBTC and other DeFi tokens to such attacks. Wallet providers like Metamask recommend adding frequently used addresses to users' address books to avoid falling victim to such scams.
