Detection Guidance

Detecting brute-force attempts on the Smart Video Intercom System requires monitoring login attempts and response patterns. Check for repeated failed login attempts from the same IP address or unusual traffic spikes targeting the device's web interface. Use network monitoring tools like Wireshark to capture and analyze HTTP POST requests to login endpoints. Inspect logs for multiple rapid authentication failures, especially for accounts that do not exist.
