Is Your Timespace Safe? - Time and Position Spoofing Opensourcely
summary
Demonstrates working GPS spoofing using open tools: GPS-SDR-SIM fed to cheap SDRs (HackRF/BladeRF/USRP) at hardware cost ~ $300–$400, producing baseband samples (default 3 minute sample limit) that successfully overwrite iPhone and Apple Watch location and time, corrupt photo timestamps and fool Uber/DD taxi and map apps; Wi‑Fi positioning spoof uses a Linux laptop with iw/MDK3 beacon floods after collecting ~20 SSID/BSSID samples by taxi to replay a fake location; attackers also induce LTE base station sync errors (measured frequency drift ~5–11,000 Hz). Suggestions include cross‑verification, shorter GPS cache life, and prioritized NTP over SSL.
