I knew I didn’t like the sound of these things. Researchers were able to break the encryption used in RFID devices such as Exxon Mobil’s Speedpass…as well as newer-generation automobiles. Now I don’t know if that refers to such cars at the autoshow that auto-start when your bluetooth key gets close enough, but that sounds like such a horrible idea to me.
There are so many bluetooth issues currently out there, that I can only imagine what people would do if they could sniff your bluetooth “car key”. I’m sure there must be more to it, but it’s still scary.
