In the world of crypto, hackers rarely break encryption; they usually "break" people. Social engineering—manipulating your emotions (fear, greed, urgency)—is the scammer's most effective weapon. You don’t need to be a programmer to defend yourself. You need to be a skeptic. Here are 5 red flags that should immediately trigger an alarm in your head.
1. Fake Support (Impersonators)
You have a problem with a transaction, so you ask for help on a project’s Telegram or Discord. Suddenly, you get a DM from "Admin" or "Help Desk." They are very polite and helpful. They ask for only one thing: "synchronize your wallet" by entering your 12 seed words on a special website.
The Verdict: This is a SCAM. Real support will never DM you first and will never ask for your seed phrase.
2. Phishing and "Poisoned" Links
Scammers buy ads on Google that look identical to popular protocols (like Aave or Lido) but lead to fake websites. When you connect your wallet there and approve a transaction, you are giving the thief permission to withdraw your tokens.
Defense: Always check the URL. Bookmark trusted sites and access them only via bookmarks, never via search engines.
3. Malicious Airdrops
You log into your wallet and see thousands of dollars in unknown tokens you never bought. It looks like free money. To swap them, you visit the website listed in the token's name and connect your wallet.
The Trap: The moment you approve the "sell" transaction, you sign a malicious contract that drains your wallet of your real assets (ETH, USDC). Ignore and hide these tokens.
4. Rug Pulls
A new project promises astronomical returns (10,000% APY). It looks great, and the price is skyrocketing. Suddenly, the developers withdraw all the liquidity from the market, and the token price crashes to zero in a minute. You are left with worthless numbers.
Defense: If something sounds too good to be true, in crypto, it is 99% likely a scam. Check if the project has security audits and who the creators are.
5. Unlimited Approvals
When using a DeFi app, you must grant it permission (Approval) to spend your tokens. Many apps ask for access to an infinite amount of funds for convenience. If that app is hacked in the future, attackers can drain everything from your wallet, even without your action.
Advice: Regularly check and revoke permissions for old contracts using tools like Revoke.cash.
Summary:
In crypto, the rule is "limited trust." Scammers prey on your greed and lack of knowledge. Before you click, take a deep breath. Your safety depends on your vigilance.
