Two wallets received most of the stolen funds, which made up 65% of all losses in this category. Signature phishing works differently. It pushes users to sign harmful on-chain actions, such as approvals that give attackers control over tokens.

Web3 Antivirus reported on February 5, "Address poisoning is one of the most consistent ways large amounts of crypto get lost".

The firm has tracked losses from this method that range from $4 million to $126 million. It added that recent cases show no signs of decline.

Researchers explained how attackers design these fake addresses. They “generate full addresses that match the same first/last few characters you see, but the middle is different, so it looks 'identical'".
