There's nothing quite like taking a slightly frightening message and flipping into something positive, but for security mastermind Andrea Barisani, that's precisely what he's done. Just weeks after pointing out all the potential dangers surrounding RDS-TMC hacks on your GPS, the Inverse Path researcher set out to CanSecWest aiming to boast about its utility. By procuring a relatively inexpensive ($40) RDS encoder, an FM transmitter, and a handheld antenna, hackers can reportedly track down the codes used "to denote a particular event," and then pipe the information into the navigation system in order to create automatic re-routing for avoiding upcoming accidents and traffic jams. By injecting the "spoofed alerts," the driver's NAV will then be able to recalculate routes on the fly without badgering you, and all that saved time could certainly end up paying dividends. Sure, this same technology is available in much less vulnerable forms, but who's down with paying a monthly premium if you can (legally) snag it from thin air?
