Web3 multi-chain wallet BitKeep has released V7.3.7, which strengthens the signature authorization security mechanism and risk reminders, especially adding reminders for eth_sign risk signatures. BitKeep officially stated that some phishing websites abused the eth_sign signature function to conduct blind signature fraud. In order to ensure the security of user transactions, BitKeep Wallet has taken active risk warning measures and issued security warnings to users. In addition, BitKeep has also strengthened its defense against risky domain names, phishing websites, risky currency collection addresses and contracts. BitKeep cooperates with third-party security agencies, accesses Github open source library and Go+ open source security address library, identifies phishing websites and more than a dozen types of risky addresses and contracts, and conducts risk identification and prompts when users connect to wallets and authorize signatures to reduce Risk of Loss of User Funds.
