Mars Finance News, Slow Fog Cosine disclosed that the phishing technique of using similar first and last digit addresses to poison is still widely prevalent, seriously affecting the security infrastructure of the blockchain industry. Cosine pointed out that there are various techniques for this type of poisoning and pollution of wallet transaction history, including fake token contract code issuing false event logs to deceive block explorers and wallets, as well as 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 transactions are from their own operations. Other common techniques include sending small amounts of funds from source addresses with the same first and last characters, combined with clipboard hijacking technology, as well as impersonating well-known decentralized exchanges to output false event logs. Cosine suggested that users should make good use of the wallet whitelist mechanism, carefully check the complete address, and use well-known hardware wallets for double verification as a defense measure. Previous news indicated that within the past 14 hours, two addresses were attacked by "transaction history pollution", resulting in a total loss of over $140,000.
