Reverse Engineering of a Not-So-Secure IoT Device

The Internet of Things is coming! It started out as overused marketing hype with no real use case (who needs internet-connected fridges? And who wants the internet-connected toilet paper?).

New ‘things’ start to pop up, whether useful or not: from smart bulbs (Philips Hue), thermostats (Nest), smart TVs (Samsung and others), to voice assistants (Alexa, Cortana, Google). You might even have installed one of these, right? What about temperature and humidity sensors? There is probably nothing wrong with that?
