Before his business trip, he asked his wife to help transfer some funds. After getting off the plane, he found that his wallet was empty. His wife cried on the phone: "I just pasted the mnemonic phrase, there was no transfer operation at all!"
What seemed like an ordinary paste caused 3 million U to vanish.
It turned out that she temporarily stored the mnemonic phrase in WeChat, the old phone had not changed its password, the home WiFi had not been updated for years, and she had installed a so-called "financial assistant" plugin—this series of habits allowed hackers to listen to the clipboard for a long time. Pasting resulted in theft, assets disappeared instantly, and there was not even a transfer record.
How to avoid similar tragedies? Three key rules must be remembered:
The mnemonic phrase is vital
Be sure to write it down on a metal plate or a dedicated mnemonic card, never take a screenshot or store it on any electronic device. According to statistics, about 70% of digital asset theft cases are due to the leakage of mnemonic phrase screenshots.
Use a "clean" device for wallet operations
Dedicated devices should not install unrelated applications or connect to public WiFi, and remain vigilant against various "market plugins" and "financial tools".
Family operations require on-site or video supervision
If assistance from family is necessary, it is recommended to start a real-time video, verify the last four digits of the recipient address before the transfer, and confirm in person.
Hacker servers usually clean logs every 72 hours, and many users find that key evidence has long disappeared when they discover they have been stolen. Please take action now: check if your mnemonic phrase is saved in handwriting, delete unknown browser plugins, and inform your family—digital assets are real money.
Security in the cryptocurrency world is not only a technical issue but also a reflection of daily habits. Your caution regarding assets is the strongest defense against malicious activities.
