SlowMist Cosine revealed that the phishing technique of poisoning similar addresses at both ends is still widespread, seriously affecting the security infrastructure construction of the blockchain industry. Cosine pointed out that there are various techniques for poisoning the transaction history of wallets, including false token contract code issuing false event logs to deceive block browsers and wallets, and using zero-amount transfer event logs to arbitrarily fill in addresses in the from/to fields. These techniques can make users mistakenly believe that the transaction comes from their own operation. Other common techniques include sending small amounts of funds from addresses with the same starting and ending characters, combining clipboard hijacking technology, and outputting false event logs of well-known decentralized exchanges.

Cosine suggests that users should make good use of wallet whitelisting mechanisms, carefully verify complete addresses, and combine well-known hardware wallets for double verification and other measures for defense.
