Cảnh báo: Lừa đảo “đầu độc địa chỉ” gia tăng mạnh trên Ethereum sau nâng cấp Fusaka

ETH-4,77%
USDC-0,02%

Một mô hình đáng lo ngại đang xuất hiện trên mạng lưới Ethereum khi các chiến dịch lừa đảo tự động lợi dụng thói quen người dùng thay vì khai thác lỗi kỹ thuật. Ngày 12/3/2026, Etherscan cảnh báo các cuộc tấn công “address poisoning” đang tăng nhanh, trong đó kẻ xấu dùng bot gửi hàng loạt giao dịch “dust” giá trị cực nhỏ để chèn các địa chỉ ví giả mạo vào lịch sử giao dịch của nạn nhân.

Sau khi nâng cấp Fusaka vào cuối năm 2025 giúp giảm phí giao dịch, quy mô các chiến dịch này tăng mạnh: số giao dịch dust của Tether (USDT) tăng 612%, USD Coin (USDC) tăng 473% và Dai tăng 470%. Đầu tháng 3/2026, một người dùng được cho là đã mất khoảng 24 triệu USD sau khi vô tình gửi tiền tới địa chỉ ví giả. Các chuyên gia khuyến nghị người dùng luôn kiểm tra toàn bộ địa chỉ ví trước khi chuyển tiền, đồng thời sử dụng các công cụ đánh dấu địa chỉ tin cậy để giảm nguy cơ bị lừa đảo.
