The track data is extracted off GPS signals. The track data should be viewed with skepticism any time an aircraft is flying near an area of known GOS jamming or armed conflict of any kind. Additionally, sometimes aircraft will spoof their ADS-B signal that they broadcast so as to be less easy to track and target.
