Ethereum Address Poisoning Attack

Ethereum Address Poisoning Attack Results in $50,000 USDT Loss

A cryptocurrency user has lost approximately $50,000 in USDT to an address-poisoning attack on Ethereum, according to Scam Sniffer. The fraudulent address matched the intended recipient’s first four and last six characters, highlighting the need for caution when sending cryptocurrency payments.

The security platform shared the two addresses alongside a transaction-history screenshot showing the misdirected payment. Address poisoning exploits familiar-looking payment records, where attackers monitor token transfers, often involving stablecoins, then generate an address resembling one the target has used.

How Address Poisoning Works

According to MetaMask, address poisoning is a scam that places a lookalike address in a user’s transaction history. Attackers can put the imitation into the target’s activity record with a negligible-value or zero-token transfer. The attacker waits for the user to copy the wrong destination when preparing a later payment.

• Attackers monitor token transfers, often involving stablecoins.
• Generate an address resembling one the target has used.
• Put the imitation into the target’s activity record with a negligible-value or zero-token transfer.

Previous USDT Thefts Involved Planted Addresses and Test Transfers

In an earlier case, a user lost approximately 100,000 USDT after selecting an imitation address planted in the wallet’s history 66 days earlier, according to Cyvers Alerts. The victim relied on the historical record without comparing the entire destination.

A separate case involved a trader who transferred 49,999,950 USDT to a fraudulent destination after first sending a 50 USDT test payment to the intended recipient. The attacker inserted a 0.005 USDT dust transaction into the victim’s history before the larger payment.

MetaMask Security Measures

MetaMask says its wallet compares a proposed destination with addresses in the sender’s transaction history. If a new destination closely resembles a previously used address, the software displays a blocking warning before submission.

MetaMask recommends saving verified destinations in Contacts. The wallet provider also warns users about the risks of address poisoning and advises them to be cautious when sending payments.

Explorer Filtering and Address Poisoning

Binance co-founder Changpeng Zhao criticized transaction-history spam after a user reported receiving 89 address-poisoning emails in less than 30 minutes following two stablecoin transfers on Ethereum. Zhao called on blockchain explorers to remove malicious entries.

Etherscan issued a warning about the method, explaining that attackers try to persuade users to copy similar-looking destinations from transaction history. Zhao acknowledged that filtering could affect small payments between AI agents and suggested using AI to distinguish legitimate transfers from spam.

Ledger Warning on Dummy Transactions

In June 2024, Ledger warned about dummy transactions designed to make users believe they had previously sent funds to an attacker’s address. The company advised users to hide unwanted tokens and NFTs in the wallet interface and avoid interacting with suspicious assets or their associated addresses.
