mqXSS 0.2
mqXSS is a client to communicate with XSS hooked browsers over
MQTT. Similar to xsshunter or beef, mqxss allows interaction with
remote browsers that have been injected with a XSS payload.
However, instead of having the victim connect back to your server
they connect through a Secure Websocket MQTT broker instead. This
tool facilitates the JS payload generation and interaction with
hooked browsers that communicate over WSS MQTT brokers.
