Chainaanalysis 發現 82K 錢包與地址投毒騙局有關
地址中毒是一個看似簡單的騙局，但即使是經驗豐富的加密用戶也會受到影響。 Chainaanalysis 發現了多達 82K 的錢包與針對高餘額用戶的活動有關。
地址中毒仍然是最常見但最有效的攻擊之一。公共區塊鏈揭示了trac餘額的錢包，機器人瞄準了它們，希望將技術攻擊與人爲錯誤結合起來。中毒地址是在短時間內創建的，但一旦受害者在鏈上再次活躍，個人損失就會多次發生。過去一天，由於從交易歷史記錄中複製的中毒地址，導致一筆 57,000 美元的損失。

Chainalysis has tracked down 82K wallets tied to attempts at poisoning by posting fake zero-value tokens. The address poisoning scam is also similar to the zero-value token attack, though with the added generation of a confusing address. Tools for poisoned address attacks are also distributed on darknet markets.
The attack depends on users not verifying their addresses closely enough, by issuing similar digits at the beginning and end of the address. The attack hinges on crypto user habits of only checking the first and last four digits of an address.
Some of the most common fake tokens or zero-sum transactions involve USDT, TRX, or MATIC, or a faked version of the token. A part of the transactions also copy the amount previously used, creating a similar-looking wallet entry. Others send entirely new tokens as an airdrop. The wallet itself is not hacked in this type of attack, and there is no risk to the funds when receiving seeding transactions.
Poisoned address scams may target even small balances, but this type of attack was behind one of the biggest losses in 2024. Poisoned addresses managed to drain $68M Wrapped BTC (WBTC) from a single wallet.
In this case, the exploiter later returned the funds, after earning $3M due to the appreciation of BTC at that time. The victim contacted the exploiter through Ethereum micro-transactions with messages attached, leading to a full refund three days later.
Poisoned addresses still spread on Ethereum
The large-scale heist helped Chainalysis discover more poisoned addresses. A total of eight wallets were responsible for launching the fake addresses during a campaign-like, concentrated event.
Chainalysis discovered a total of 82,031 spoofed addresses, which resemble legitimate counterparties. The newly created poisoned addresses were close to 1% of all new Ethereum wallets launched in a similar time period.
The network of poisoned addresses managed to scam more experienced users with a higher wallet balance. A total of 2,774 wallets sent funds to the faked addresses, diverting a total of $69.72M. The wallets contained up to $338K, though most held smaller sums of $1,000. What was also common is that the victims were usually active traders and Ethereum users.
The wide network of poisoned addresses had a relatively small success. Of the wallets targeted, 756 caught the scam with a test transaction or a smaller sum under $100. The transactions sometimes even spoofed the victim’s own wallets. In that case, owning a human-readable ENS address could mitigate the risk.
Similar campaigns have ran on Binance Smart Chain, with the Binance team now flagging zero-value transactions and spoof addresses. Reports of Toncoin (TON) poisoned addresses have also surfaced, with 0 TON transactions as the bait.
Scammers launder funds through DeFi and exchanges
While the biggest $68M haul was not laundered efficiently, smaller sums could be disguised and liquidated. Scammers used DeFi protocols, then centralized exchanges to both clear their tracks and swap the initial funds.
Some of the exchanges involved in the scam were no-KYC markets in Eastern Europe, with less stringent regulations on the origin of funds. The transfers to an exchange were the last leg of the destination, after mixing the funds through DeFi protocols and decentralized markets.
Campaigns of seeding wallets are usually short, but can have outsized earnings. Block explorers have started flagging the fake transactions, so users can check their history before sending funds.
