A crypto investor lost $2.5 million in stablecoins due to a double phishing scam.

The scam utilized a zero-value transfer technique, tricking the victim into sending real funds.
-
This incident underscores the growing threat of phishing attacks in the cryptocurrency sector.
Understanding Zero-Value Transfer Phishing
Zero-value transfer phishing is an advanced form of on-chain phishing that manipulates token transfer functions. Here’s how it works:
-
Initial Transfer: The attacker sends a zero-value token transfer from their address to the victim's wallet. This transaction appears in the victim's transaction history.
-
Trust Misplaced: The victim, seeing the transaction, may mistakenly believe the address is safe and send real funds to it in a future transaction.
-
Loss of Funds: The victim unknowingly sends their stablecoins to the attacker’s address, resulting in significant financial loss.
This method is particularly dangerous because it does not require a signature from the victim’s private key, making it easier for attackers to execute.
The Double Phishing Attack
In this case, the victim was scammed twice within a three-hour window:
-
First Transaction: The victim sent 843,000 USDT (Tether).
-
Second Transaction: Approximately three hours later, they sent an additional 1.75 million USDT.
The total loss amounted to $2.5 million, showcasing the effectiveness of the scam and the need for increased awareness among crypto investors.
Evolution of Phishing Techniques
Zero-value transfer phishing is considered an evolution of address poisoning, where attackers send small amounts of cryptocurrency from addresses that closely resemble the victim's real address. This tactic aims to trick users into copying and pasting the attacker's address in future transactions, leading to accidental losses.
Growing Threat Across Blockchains
The threat of phishing attacks is on the rise across various blockchain networks. A recent study revealed:
-
Over 270 million poisoning attempts occurred on BNB Chain and Ethereum from July 2022 to June 2024.
-
Approximately 6,000 of these attempts were successful, resulting in losses exceeding $83 million.
As the cryptocurrency landscape continues to evolve, so do the tactics employed by cybercriminals. Investors must remain vigilant and adopt best practices to protect their assets.
Conclusion
The $2.5 million loss suffered by the investor serves as a stark reminder of the risks associated with cryptocurrency investments. As phishing techniques become more sophisticated, it is crucial for users to educate themselves about potential scams and implement security measures to safeguard their digital assets. Awareness and caution are key in navigating the ever-changing world of cryptocurrency.
