The Message Queueing Telemetry Transport (MQTT) protocol is a standard protocol for Internet of Things implementations. Issues arise when users of products and software utilising MQTT (and IoT generally) are unaware that the data they store might not be as safe as they would assume. From singular, residential IP addresses for a given home automation setup, to cloud services managing IoT products, to public brokers which can be used to aggregate vast quantities of data (popular and free for developers to use in testing), MQTT endpoints beacon data across the globe which sometimes can be as sensitive as live GPS co-ordinates and personal details of entire families as they go about life. From tracking Teslas to surveying Supermarkets, this talk will cover a 2 year journey from first discovering the goldmine of MQTT data, through being able to interact sanely with and search through such large datasets, to the technical difficulties (and moral repugnance) of building data collection automation. Included: MQTT, Python, geoJSON, Shodan, Censys

If you pop out into space, you die. No oxygen to breathe, no ambient pressure makes your bodily fluids boil, UV radiation burns your skin to a crisp. It's not a good place to be for humans. So in order to survive, you need to bring a number of things along, commonly called the "life support system". This talk explains how this works!
