A Trader Just Lost $1 Million by Clicking One Bad Transaction — Here's How to Make Sure It Doesn't Happen to You
(85 days ago) · 1 source · Summarized by CryptoBipto
A crypto trader lost approximately $1 million after unknowingly signing a malicious token approval, granting a phishing attacker permission to drain their wallet. The incident highlights the persistent and growing threat of approval-based phishing scams in decentralized finance.
WHY IT MATTERS
In crypto, when you use a decentralized app (dApp), you often have to give it permission — called a 'token approval' — to move your coins on your behalf. Think of it like giving someone a signed blank check: if you trust them, it's fine, but if a scammer tricks you into signing one, they can drain your account. That's exactly what happened here. A trader signed what looked like a normal transaction but was actually giving a thief permission to take their tokens. This is why it's critical to double-check every transaction you sign, use trusted websites, and periodically review which apps have permission to access your wallet.
