California's highway toll tag system has been compromised according to an article over at Tech Review:|
In the past, authorities have insisted that the FasTrak system uses encryption to secure data and that no personal details are stored on the device--just two unique, randomly assigned ID numbers. One of these is used to register the device when a customer purchases it, while the other acts as a unique identifier to let radio receivers at tolls detect cars as they pass by.And here we go again - the same fault in these is probably all over the place.
But when Lawson opened up a transponder, he found that there was no security protecting these IDs. The device uses two antennas, one to detect a request signal from the toll reader and another to transmit its ID so that it can be read, he says.
