# Tether Swiftly Blacklists Phishing Address After $20M Theft

#### Share this article

A zero transfer scammer stole $20 million worth of Tether (USDT) on August 1, only to be quickly blacklisted by the stablecoin’s issuer.

> Curious who this would be if it was blacklisted within ~1 hr

The scam involved the victim receiving $10 million from a Binance account, intending to send the amount to a specific address. However, it was redirected to a phishing address that resembled the intended one, with the victim subsequently sending 20 million USDT to the scammer’s address.

The deceptive method used is known as a zero transfer attack, where the scammer sends a 0 token transaction from the victim’s wallet to a similar-looking address. Confused by the similar address, the victim may then send funds to the wrong recipient.

The funds were sent to a phishing address: 0xa7Bf48749D2E4aA29e3209879956b9bAa9E90570, instead of the intended 0xa7B4BAC8f0f9692e56750aEFB5f6cB5516E90570.

Tether’s immediate action was to freeze the wallet, with some [wondering](https://twitter.com/alphador_ai/status/1686355906139762689?s=20) if “someone serious owned address A.”

This particular scam technique involves the perpetrator sending zero tokens from the victim’s wallet to a slightly tweaked address. Consequently, the victim may confuse this counterfeit address for a legitimate one when checking their transaction history, leading them to mistakenly send their assets to the scammer.
