Twitter user Tedtheeast said that DigiDaigaku appeared on the Super Bowl, which attracted a lot of traffic to the NFT circle, but also caused many people to have their NFTs stolen by phishing links. If you are stolen, you can take the following measures: 1. First, make sure that the theft is caused by signature rather than authorization. The difference lies in whether the gas fee is paid. You can check it on the blockchain browser. You can also cancel any authorization that looks suspicious on revoke.cash. At the same time, evoke.cash also has a wallet plug-in for browsers that can prompt malicious websites. 2. Make sure that the mnemonic has not been leaked. If the mnemonic has been leaked, there is no other way except to change the wallet. 3. The theft of NFT and ETH due to signature is a one-time thing. After all, for many people, wallets are not something that can be changed casually.
