Binance Warns One Wrong Copy-Paste Can Send Crypto to an Address-Poisoning Scammer

A crypto wallet can be perfectly secure and still send money straight to a scammer.

That is the danger behind address poisoning, a low-cost trick that turns a wallet’s own transaction history into bait. The attacker does not need to break the wallet or learn its seed phrase.

Instead, the scammer creates an address that resembles one the victim has used before. A tiny transfer then plants that lookalike in the visible history, waiting for the user to copy it during a later payment.

Binance Academy explains that the trap works because long hexadecimal addresses are hard to compare at a glance. Attackers often mimic the opening and closing characters people are most likely to check.
