Last night, I received a voice message from an old fan, trembling with emotion: "Bro, three million... it's gone. Just because I asked my wife to help transfer some money."

Having been in this circle for eight years, I have seen countless people flip due to greed. But this time is different—pure negligence has led to disaster.

Here's the thing: Before his business trip, he took the easy route and sent a screenshot of his wallet's mnemonic phrase to his wife via WeChat, asking her to help transfer some assets. When he landed and opened the wallet, the balance showed "0". All the money had evaporated.

Going to the police station, the officer shook his head after reading the record: "This is caused by the family’s operation, it will be treated as a civil dispute, no criminal case can be established." His wife cried so hard that she couldn't speak, repeatedly saying: "I just pasted the mnemonic phrase, I didn't even touch the transfer button!"

The real reason is frightening. After checking his wife's phone, he found that the Android device that had been used for four years was still connected to the home WiFi that hadn't changed its password for three years, and the browser still had the "Financial Assistant" plugin that was popular during the last year's money-making craze.

It's this seemingly harmless plugin that has been secretly monitoring the clipboard in the background. The moment the mnemonic phrase is copied, the data is sent to the hacker's server. At the moment she logged into the wallet, three million in digital assets were transferred away at lightning speed, leaving no transaction record behind.

Similar things happen two or three times every month. This is not alarmist—many people are completely unaware that the risks in this circle are never just in the fluctuations of the K-line.
