Guarding from eth-sign Scams: Important Tips

  The eth-sign signature scam has been an active method of fraud, where many cryptocurrency users fall victim to phishing websites or receive suspicious messages on social platforms like Telegram. These messages often request users to sign and authorize malicious messages using eth-sign in exchange for claiming airdrop rewards. Due to a lack of scrutiny or a basic understanding of eth-sign, users may perceive such signature authorization as a normal operation. Consequently, they unknowingly sign the messages, leading to their accounts being compromised and funds being stolen by scammers.

  To help more cryptocurrency users become fully aware of and protect themselves against such scams, Bitget Wallet (Previously Bitget Wallet (Previously BitKeep)) aims to provide an explanation of what eth-sign is and how to utilize Bitget Wallet (Previously Bitget Wallet (Previously BitKeep)) to prevent eth-sign fraud. This initiative aims to enhance everyone’s security when engaging in daily transactions or interacting with Web3 projects.

What is eth-sign?

Eth-sign is a method of message signing for Ethereum accounts. It allows the account holder to sign any hash, which means it can be used to sign transactions or any other data. However, this type of signature is extremely dangerous and can be likened to a “blank check” for Ethereum.

Once a scammer obtains your signature authorization through a phishing website, they can use your private key to sign any transaction, including transferring all your funds to the scammer’s address. Even if you disconnect your wallet from the phishing website, it cannot undo the damage. Once they have the signature, they can directly manipulate your assets without linking them to your wallet.

For example, when you connect your wallet to a phishing website pretending to be a well-known project and claim an airdrop, the wallet will display a popup warning about the signature and the associated risks. However, it is difficult for regular users to discern the exact content of the signature from the popup, and they might mistakenly consider it as a general authorization confirmation. Once the signature is made, the scammer can freely steal all the assets from your address without restraint.
