3. Not much time! IoT? • Pytrack & LoPy4 shield • From pycom.io, about 100€ • ESP32 with Micropython • Also, RGB-LED  3
4. What is Wardriving? Used to be: • Scanning for nearby WiFis • open ones, and weakly protected • Nowadays: geolocation • Android / iPhone / …, they all do it • Remember “Locationgate”, sometime 2010? 4
5. Presenting: WARPY What is warpy? • Software for collecting it all! • Store it on microSD card • Roughly gets position every 4 seconds • Code is on github: https://github.com/palladionIT/warpy 5
6. Presenting: WARPY But Why? • Power consumption! • Not even 1 watt • 100h+ with powerbank 6
7. Results Ring • ~1000 SSIDs • 14 minutes 7
8. Results Ring Here: • Just open WIFIs 8
9. Results Gürtel • ~2500 SSIDs • 25 minutes 9
10. Open issues • Accuracy of GPS unknown • “Smarter” collection strategy needed • Upload to wiggle / export to public • Map Vienna! 10
