mitmrouter

mitmrouter is a Bash script that automates standing up a Linux box as a router. For hardware and IoT research this is a fast way to get a device onto a network you fully control, so you can watch and manipulate everything it sends.

Good for:

• Capturing and analyzing an IoT device's network traffic.
• Setting up SSL/TLS MITM to inspect encrypted communications.
• Quickly building a controlled test network without hand-configuring hostapd, dnsmasq, and iptables.

Notes: Open source (GitHub). Pair it with a TLS interception tool to inspect HTTPS traffic from the device under test.
