This Python script detects if someone is following you, by using wardriving data to determine if a unique MAC address appears at multiple locations. This works by sniffing for Probe Requests, a type of WiFi frame that reveals networks you've joined in the past!
We use Jupyter Notebook for this proof-of-concept to visualize the data, and the Folium mapping library as well as Pandas for data analysis. You can try out this example in Google CoLab
The data capture in this demo uses Kismet Wireless on a Raspberry Pi.
