Recently, I’ve seen many people in the community get their U stolen, so I think it’s time to have a serious talk about this topic. It takes five minutes to deposit $500k into a bank, but clicking on a U theft link disappears in less than a second—that’s not alarmist talk.

Domestic scammers have now upgraded from traditional telecom fraud to cryptocurrency scams, and their tactics are becoming more sophisticated. The main reason is that virtual currencies are not legally protected domestically, and victims’ reports are often ignored because many law enforcement agencies don’t even understand what USDT is, let alone investigate. This gives scammers plenty of opportunities.

Currently, I’ve summarized three common types of U theft scams that trap the most people. The first is QR code contract authorization. Scammers send you a QR code during a transaction, asking you to scan it, but it’s not a transfer at all; it’s a smart contract that controls your wallet. Normally, scanning a QR code shows a transfer address, but scam QR codes reveal a third-party redirect link. This is especially easy to fool beginners, because they’re dazzled by high returns and think they’ve struck it rich.

The second type is clipboard viruses. Scammers send you a trojan file with an enticing name. When you download and open it, any transfer link you copy will be tampered with. For example, if you copy an address ending in 123, it might change to 567 when pasted. So never click on unfamiliar download links.

The third and most vicious type is fake wallet theft. Since cold wallets are open source, it’s not hard to clone one. Scammers first lure you with high returns to download a fake wallet. Small transfers in the beginning are fine, but once a large amount is deposited, the fake wallet will block your account and demand a deposit to unfreeze it. At this point, it shifts from a scam to a “pig-butchering” scheme, continuously draining your funds until you have nothing left.

In short, the scam of U theft is about first tempting you with dreams of overnight riches, then gradually setting traps. My advice is: don’t be fooled by the illusion of quick wealth. Before you’re attracted by high returns, scammers are already eyeing your principal. Protect your wallet—nothing is more important.
