💥 8.43 million USDT, it wasn't stolen, he 'agreed' to send it out himself
It wasn't a hacker intrusion.
It wasn't a private key leak.
It was just—he clicked an 'agree' himself.
Three days later, 8.43 million USDT was instantly cleared.
He couldn't understand:
Ledger cold wallet
Private key was never online
Mnemonic phrase written on paper
No screenshots, no photos, no sharing
With security airtight, how could it still be lost?
After looking at the on-chain records, I can only say: authorization.
The situation is simple—
He wanted to conveniently check his assets, so he installed a browser extension wallet, connected it to Ledger.
This extension appeared flawless:
✅ Cold wallet synchronization
✅ Clean interface + coin price
✅ Community reputation was quite good
He thought it was just to 'check the balance', with no risk.
As a result, when connecting, he clicked to authorize the signature.
This transaction was like giving an unlimited blank check—transfer permissions were fully given to someone else.
Three days later, as soon as 8.43 million USDT arrived,
The hacker directly called the contract and swept everything away.
No prompts, no confirmations—because you had already signed.
On-chain review:
SetApprovalForAll standard contract
Authorized object: hacker's aggregation contract
Transferred the full amount on the day it arrived
The transaction record only left one call event
We intervened, locked the authorization source and fund flow, marked the hacker's address, contacted the exchange, and currently, part of the funds have been frozen.
This incident again proves:
❌ Cold wallet ≠ invincible
❌ Hackers don't need to hack your private key
✅ If you sign incorrectly, it's like handing over the warehouse key
📌 The biggest trap in the cryptocurrency world has never been vulnerabilities, but that moment you thought was 'very safe' when you clicked.
