An Ethereum investor has lost more than $12 million due to a complex address poisoning scam, showing the risks associated with convenience-focused transactions in the crypto space. The user accidentally transferred 4,556 ETH, which is valued at approximately $12.4 million, to a malicious wallet that appeared legitimate.

How the Scam Worked

The Ethereum user, who frequently sends funds to the legitimate recipient, copied the address from their transaction history without verifying it in full. Due to the fraudulent address being nearly identical, the user did not notice the difference and sent the entire balance to the hacker.

This type of attack, known as an address poisoning scam, is growing in the crypto ecosystem. Scammers rely on users’ everyday behavior—and the potential of not carrying out meticulous verification for an action that is familiar—to execute large-scale thefts

A similar case was reported in December 2025, another investor lost $50 million after copying a spoofed address. In that incident, a small test transfer of $50 was manipulated by the attacker to trick the user into sending the remaining balance to the fraudulent wallet.

Caution For Cryptocurrency Users

The incident highlights the importance of exercising extreme caution when sending crypto funds. Users are advised not to rely solely on copying addresses from previous transactions or partial verification based on familiar characters. Full address verification is highly necessary because scammers are relying on partial verifications

Other safety measures include using ENS domains, wallet address books, or dedicated verification tools to confirm the legitimacy of the recipient’s address. These practices can help prevent the loss of significant funds to address poisoning or other forms of wallet spoofing.

This incident is evidence that even experienced investors can fall victim to scams, especially address poisoning attacks. While copying addresses and prioritizing speed may seem convenient, it can result in devastating financial losses that may never be fully realized. Careful verification and cautious transaction practices cannot be overemphasized for anyone handling substantial cryptocurrency holdings.
