"...The Russians have started hacking into the global navigation satellite system (GNSS) on a mass scale in order to confuse thousands of ships and airplanes about where they are, according to a study of false GNSS signals by C4AD.

Your phone, law enforcement, shipping, airlines, and power stations — anything dependent on GPS time and location synchronization — are all vulnerable to GNSS hacking.
