Spoofing cell networks and GPS signals with a $5 USB to VGA adapter. Using USB 3.0 VGA adapters based on the Fresco Logic FL2000 chip as a sofware defined radio transmitter.
After reverse-engineering the USB protocol of the FL2000 in 2016, Steve Markgraf discovered through experimentation that it is possible to operate the FL2000 in a way that both horizontal and vertical synchronization are disabled, thus creating a continous stream of samples. This work resulted in osmo-fl2k, which so far was used to transmit low-power FM, DAB, DVB-T, GSM, UMTS and GPS signals.
