ChainCatcher news, according to the official announcement, to further enhance the security of Web3 wallets, the OKX Web3 wallet has now upgraded its interception strategy for risky transactions. The currently interceptable risky transactions are as follows:Malicious authorization to EOA accounts. Generally, DApp authorization is given to contract accounts, not EOA.Maliciously changing your account owner. Once signed, you will lose control over the account. This usually occurs on public chains like TRON and Solana, where there is an account owner design.Maliciously changing your transfer address. A small number of DApp contracts are poorly designed, but the OKX wallet can identify the risks.Intercepting transfers to similar addresses. This attack method involves: the attacker generating an address that is very similar to one you have recently used (the characters at the beginning and end are the same), transferring a large amount of fake USDT to you, increasing the probability of being copied as a hacker address in the transaction history page.According to the OKX Web3 wallet prompt, if users see related risk interceptions while conducting on-chain transactions, please proceed with caution. Currently, users need to upgrade the OKX APP to version 6.74.0 or above, or upgrade the OKX Web3 plugin wallet to version 3.1.0 or above to immediately experience this feature.
