A pair of hackers have demonstrated a way to spoof travel information
messages displayed on satellite navigation systems used by Italian
drivers to bypass accidents, traffic jams and plot the most efficient
routes from one point to another.
The hack is so simple it's hard to believe no one has shown it off
before. It uses inexpensive, off-the-shelf gear to inject RDS-TMC
(radio data system-traffic message channel) data that is digitally
coded into FM signals that many satnav systems use to receive travel
information in real time.
