Recently, I came across a piece of industry news: well-known trader He Yi's WeChat account was hacked. Interestingly, the hacker used Moments to post a Meme coin, encouraging WeChat friends to participate, promising that once the market cap reaches 100M, it will be listed on major exchanges.

The news spread quickly within the industry. Many of He Yi's WeChat contacts went to mock the hacker, but surprisingly, the hacker accepted all comments without rejection.

Later, technical investigations revealed the cause—an old phone number previously used by He Yi was recovered by someone else. The criminal used this number to log into WeChat, receive verification codes, and ultimately gain control of the account.

Fortunately, after several efforts, He Yi successfully regained her WeChat account. After recovering it, she was quite generous and announced an airdrop to compensate users who bought this Meme coin today, funded personally by her.

Ironically, the hacker behind this incident only managed to steal about $55,000. Honestly, that's a bit disappointing. If they truly wanted to make a big move, it might have been more effective to impersonate He Yi and leverage her influence to borrow money from big investors—probably with a higher success rate—though of course, this is just a joke.

This incident serves as an important reminder: account security and asset protection should never be taken lightly. If you have an old phone number registered but no longer use it, yet it is still linked to WeChat or other critical accounts, be sure to unlink it as soon as possible. Such "abandoned but unremoved" bindings often become security vulnerabilities, providing opportunities for malicious actors. For those working in the crypto industry, the risks are inherently more complex—both personal safety and account security deserve serious attention.
