DNS-Driveby is a $10 tracker that uses Open Wi-Fi networks for telemetry & reconaissance, instead of a SIM card. It logs GPS coordinates & other data to its internal memory, scans for un-authenticated Wi-Fi networks, and uses DNS Exfiltration through DNS CanaryTokens to bypass captive portals! Read about how I created it on Hackster!
