A hands-on walkthrough of setting up a Raspberry Pi 5 running Kali Linux as a man-in-the-middle router and proxy to intercept and inspect IoT device traffic. The guide covers installing dependencies (hostapd, dnsmasq, bridge-utils), cloning a bash script to configure a bridged Wi-Fi/Ethernet access point, configuring iptables rules to redirect traffic to mitmproxy on port 8081, and using Wireshark alongside mitmproxy to capture and decrypt traffic. A real IP camera (Hikvision) is used as a demo target, revealing it sends encrypted data on non-standard ports (85, 6900) to AWS servers, including device serial numbers, authorization credentials, and build information.
