Detection Guidance

Scan your network for Ebyte devices using tools like nmap to identify exposed web management interfaces. Check for open ports commonly used by these devices (e.g., 80, 443, 8080). Access the web interface and verify if authentication is required before allowing administrative actions. If no authentication is enforced, the device is vulnerable.
