A friend of mine used an app that detects suspicious cell towers and has been getting warnings today. He is worried about the possibility that someone may be specifically targeting him, which leads me to wonder how exactly these fake towers can be expected to work.
Will they actually target a specific number and intercept all calls made to/from that number discarding all non-targets? Or will they indiscriminately intercept all calls in a certain range?
And besides bugging cellphones and tracking their user's locations, what can these fake cell towers be used for? Are there any common schemes they are used in?
