I bought a Fire TV stick and inserted it into the HDMI-port of my TV. I was presented with a dialog to select my wireless router so it can connect online.
Just after I did that, it asked me if I am who I am.
So they were able to deduce my account just from my Wifi?
I didn't go to amazon from my "IP of the day" that day before.
How did they match my identity from my wireless network. Did my laptop communicate the ESSID to Amazon before?
