Yet another interesting application for the USRP and GNURadio.

Yeah the victim has to have the same model of pacemaker/cardiac defibrillator 
and not notice the guy next to him with all this radio/computer equipment.  I 
have heard the same concern about bad people using the ADS-B position for 
targeting aircraft.  It is possible, like turning off the pacemaker, but there 
are simpler and easier methods similar to just punching the person.

I heard that some Remote Keyless Entry Systems have been compromised as well.  
I heard stories of Mercedes-Benz owners sitting in a coffee shop in Europe next 
to a guy with a laptop and when they leave their car is gone.  This is due to 
the feature that the key only has to be in the person's pocket to unlock and 
start the car.  So the security of having to use a real physical key in a lock 
is gone.
