Ein Vortrag von Puck auf der GPN17.
While reading about the Mirai botnet I was confronted with a simple and yet profound question: How the hell could this even work? Shouldn't there be firewalls built into every router to prevent such an attack? And (almost) no one who buys an IoT device knows how to manually open the ports on their routers. So how could Millions of these things become a botnet?
This question send me on a scavenger hunt searching for a way to find the smartest device in my home network. A multi-function printer.
To get my answers I had to look into how UPnP ,and Apples alternative Bonjour, work.
