mitmproxy-mqtt-script.git

This script is ad-hoc solution for inspecting MQTT over TLS traffic.

This is a continuation of work started in mitmproxy-mqtt-script. This fork supports (almost) all MQTT packet types, multiple packets handling, and more.

Usage

Run mitmproxy as mitmproxy --mode transparent --tcp-hosts '.*' -s plugin.py. Messages will be displayed at the event log (press shift + e).

Of course before that you have to prepare a target device and your host running mitmproxy: * Install mitmproxy's root certificate on a target device. * Route device's traffic to mitmproxy. See https://docs.mitmproxy.org/stable/ for the details. * https://docs.mitmproxy.org/stable/howto-transparent/.

If server requires x509 client authentication --set client_certs=cert.pem mitmproxy's option might be useful.

Roadmap

[ ] Add support for non-HTTP flows to the UI.
[x] Implement parsing of PUBREC, PUBREL and PUBCOMP MQTT packet types.
[ ] Add support for MQTT to mitmproxy including interception, modification and replay.
