Crypto Investor Loses $908K in USDC to Sophisticated Wallet-Draining Scam

A cryptocurrency investor suffered a $908,551 loss in an advanced phishing attack after unknowingly granting transaction approval 458 days prior. This incident underscores the growing security risks in digital asset ecosystems as scams become increasingly sophisticated.

On-chain analysis shows the victim authorized a malicious transaction on April 30, 2024, likely through a disguised airdrop or fake project interface. The attacker waited over a year before draining the wallet on July 2, 2025, first transferring $762,397 in USDC followed by other assets.

This case highlights how dormant approvals create persistent vulnerabilities in crypto. Security professionals recommend regular wallet maintenance, including revoking unused permissions and implementing multi-factor authentication for protection.
