The Secret of Cryptocurrency Wallet Authorization Trap: How 500,000 Yuan Disappeared

Today, I want to tell you a real tragic case that happened in the cryptocurrency circle. A friend had 500,000 Yuan stolen from his wallet just because he transferred a USDT. I hope that through this case, everyone can avoid repeating the same mistakes.

The thing is, the scammers exchanged 1 USDT for 9.4 RMB at a high price. Does it sound tempting? But there is a deep trap behind it. The scammers claimed that the U of the exchange is easy to track, and asked the friends to withdraw U to the web3 wallet. Any wallet can be used. The key lies in the subsequent operations.

According to the instructions of the scammers, the friends created a private keyless wallet with a mobile app of a certain Yi, and then transferred USDT to this new wallet. At this time, the scammers could not control the friends' assets. Because the newly created wallet did not have TRX to pay the gas fee, the scammers also "kindly" transferred 130 TRX as gas fee, and then asked the friends to transfer him a USDT test wallet.

This step is the most important! The real purpose of the scammers is to get you to make this transfer. They will use various rhetoric, such as buying U at a high price as bait, in short, they want you to transfer a sum of money from your wallet to the other party's wallet. If you can cancel the transaction at this time, you will not be deceived, but you can also earn those TRX. But unfortunately, the friend does not know how to use the web3 wallet, and still transfers a USDT to the scammer.

Note that the TRX payment address provided by the scammer is a QR code, which looks ordinary, but actually hides a mystery. After the friend scans the code with the web3 private keyless wallet, it will jump to a web page, which has a code for defrauding authorization in the background. When the friend thinks that it is just a simple transfer of a USDT, in fact, the background performs an authorization operation, transferring the control of the wallet to the scammer's wallet address. The principle behind this is to set up multi-signature of the wallet. Friends who do not understand multi-signature can understand it by themselves.

In addition, Dao Ge has recently set his sights on a potential coin on the Ethereum chain, Musk's ͜p͜͡u͜͡p͜͡p͜͡i͜͡e͜͡s͡. I heard that it may become popular this year, so I plan to make some money in advance.
