Is there any interest in me doing a guide about guerilla Wi-Fi advertising?
I have never seen this method done anywhere, nor seen a guide anywhere.
I basically built myself a device out of a microcontroller and a battery bank which advertises fake Wi-Fi networks. (Open area range 100m~500m)
I can choose the name of those networks myself.
The Li-Ion cells in it can make this thing run up to a few days independently. If you have some solid experience in hard- & softwaredesign as well as some microcontroller programming skills you could do it from scratch. For others I would write a guide, if there is any interest around.
(Device can be programmed to do some grey-blackhat stuff aswell, maybe I will put that in the guide as well.)
The idea is that you place one or multiple of these devices in areas you know are going to be crowded.
Good examples would be a train station, a mall or other public places of some sort. Basically everwhere you know where there are going to be a lot of people around with their phones out, potentially searching for free WiFi.
This way you could potentially reach thousands of people each day, for free.
Some screenshots below of the device and the implementation (Promoted URL blurred by me).
Let me know if you would be interested, as writing a guide for noone would be way to much work since it involves quite a lot of explaining.
