A crypto wallet lost $69.3 million worth of Wrapped Bitcoin (WBTC) in an apparent address-poisoning attack, according to the blockchain security firm CertiK. Address poisoning usually involves a scammer sending a wallet a tiny amount of crypto via an address that’s designed to look similar to the wallet’s, according to an explanation provided by Ledger, a digital asset wallet provider. The ploy is designed to trick wallet holders into mistakenly copying the scammer’s address from their transaction history and having funds sent to that wallet instead. In this instance, CertiK notes that a scammer mimicked a transfer of 0.05 Ethereum (ETH), which tricked the victim into sending 1,155 WBTC worth $69.3 million to the wrong address.
