Wallet Security Guide: How to Reduce the Risk of Phishing and Fraudulent Signatures

Recently, several friends around me have fallen victim to phishing attacks on their wallets. I think it's time to talk about Web3 security again.

To put it simply: it's not that you're lucky; it's that the attacker hasn't targeted you yet.

😅

To be honest, is a cold wallet important? Yes, it is. But don't think of it as a magic amulet. If your processes are not well-managed and your permissions are not clear, no matter how expensive your cold wallet is or how well-hidden your recovery phrase is, you can still run into problems.

Moreover, the phishing tactics these days have really evolved quickly. Fake bots on TG, fake official websites on Google, email phishing, phishing in Twitter comment sections, fake management on DC... they're so skilled that they can perform better than the project teams themselves; clicking on those links can truly be the beginning of your doom.

How do I usually handle things? Here are a few suggestions; they may not be comprehensive, but at least they can help you avoid some pitfalls:

🔸

Save the official website as a bookmark; don’t use search engines. There are too many phishing sites in Google ads, and the pages look identical.

🔸

For sensitive information like private keys and recovery phrases, any page that asks you to fill them in is basically a scam by default.

🔸

Always read carefully before authorizing. Especially for those “unlimited authorizations,” if you don’t understand the signature, don’t sign it.

🔸

Separate your hot wallet and cold wallet. Use small wallets that can be discarded for small transactions, and keep your main assets in a cold wallet; don’t mix them.

🔸

Use some security plugins, like GoPlus, which can help you identify hidden dangers in advance, at least providing an extra layer of warning.

Lastly, I want to say: Web3 is truly a dark forest; surviving longer is more important than making more money.

Sometimes, your lack of issues isn’t because you’re stable, but because the hacker hasn’t targeted you yet. When something does happen, it might be too late to think about defense.
