Lost 4556 ETH because I accidentally copied the wallet address from the transaction history.

A unfortunate story from the crypto community: User A just experienced a terrifying moment when they painfully realized they had transferred 4556 ETH (worth over $12 million USD) to a scammer’s wallet. This incident once again exposes one of the common organized scam techniques on the blockchain—a type of attack that anyone can fall victim to.

The sophisticated impersonation tactic of scammers

Scammers don’t act impulsively. Instead, they monitor user A’s transaction history over a long period—continuously from wallet 0xd6741220a947941bf290799811fcdcea8ae4a7da to recipient wallet 0x6d90cc8ce83b6d0acf634ed45d4bcc37eddd2e48.

When an opportunity arises, the scammer creates a fake wallet that looks almost identical: 0x6d9052b2df589de00324127fe2707eb34e592e48—only five characters differ in the (easily confusable) positions. Then, they spam transactions from this fake wallet repeatedly to build trustworthiness in the transaction history.

One mistake, over $12 million lost in 12 seconds

User A intended to send 4556 ETH (currently equivalent to about $2.02K USD/token, total value ~ $12.33 million USD) to the official address. Instead of using a verified address, A chose the most “convenient” method—copying the address from recent transaction history.

In just 12 seconds, hundreds of millions of VND (around 320 billion VND) vanished from A’s wallet. The scammer earned a fortune—without any complex technical attack, just waiting for human oversight. That’s why you often see transaction histories with strange labels like “scam”—these are traps set by scammers in advance.

Protect your wallet from these types of attacks

Most painfully, this mistake could have been completely avoided. The golden rule: Never copy wallet addresses from recent transaction history. Instead:

• Save the official wallet address in a secure place (or enter manually)
• Always verify at least the first 5-6 characters and the last 5-6 characters before sending
• For large amounts, send a small test amount first to verify

This scammer will surely “hang up their sword” after this victory—but at least this lesson helps the community stay alert.
