Speaking to a City of Amazon Echoes

Karl Fosaaen (@kfosaaen) With over 11 million devices in the market, Amazon has invaded homes with their Echo devices. Along with that, they have introduced messaging capabilities that allow users to communicate with each other through their Echoes. This can be a handy way to keep in touch with friends, but what if we wanted to start some conversations with strangers? In this talk, we will go over how the Amazon Echo devices identify other devices and how they talk to each other. After reviewing the protocols, we will go through the process of finding all of the Amazon Echo devices in a specific region (think phone numbers) and how someone could send messages out to all of those devices to make some new friends.
