Authorized testing only. Practice on systems you own, isolated labs, or targets with written permission. Unauthorized access is illegal.

When

Your smart home uses MQTT — check for anonymous access and sensitive topics.

How

Try anonymous subscribe; list topics; enforce auth and TLS.

Why

Open MQTT brokers leak sensor data and sometimes control topics.

Commands & usage

mosquitto_sub -h 192.168.1.40 -t '#' -v
mosquitto_sub -h 192.168.1.40 -u user -P pass -t 'home/#' -v
mosquitto_pub -h 192.168.1.40 -t 'test/topic' -m 'ping'

Commands are educational examples. Adapt hosts, paths, and rates to your authorized scope.
