Instead, a hacker like Samy Kamkar may be using a clever radio hack to intercept and record your wireless keys command. And when that hacker walks up to your vehicle a few minutes, hours, or days later, it wont even take those two button presses to get inside. At the hacker conference DefCon in Las Vegas tomorrow, Kamkar plans to present the details of a gadget hes developed called RollJam. The 32 radio device, smaller than a cell phone, is designed to defeat the rolling codes security used in not only most modern cars and trucks keyless entry systems, but also in their alarm systems and in modern garage door openers. The technique, long understood but easier than ever to pull off with Kamkars attack, lets an intruder break into cars without a trace, turn off their alarms and effortlessly access garages. Julian Berman for WIRED RollJam, as Kamkar describes it, is meant to be hidden on or near a target vehicle or garage, where it lies in wait for an unsuspecting victim to use his or her key fob within radio range. The victim will notice only that his or her key fob doesnt work on the first try. But after a second, successful button press locks or unlocks a car or garage door, the RollJam attacker can return at any time to retrieve the device, press a small button on it, and replay an intercepted code from the victims fob to open that car or garage again at will. Every garage that has a wireless remote, and virtually every car that has a wireless key can be broken into, says Kamkar. Thieves have used code grabber devices for years to intercept and replay wireless codes for car and garage doors. But both industries have responded by moving the ISM radio signals their key fobs use to a system of rolling codes, in which the key fobs code changes with every use and any code is rejected if its used a second time. To circumvent that security measure, RollJam uses an uncannily devious technique: The first time the victim presses their key fob, RollJam jams the signal with a pair of cheap radios that send out noise on the two common frequencies used by cars and garage door openers. At the same time, the hacking device listens with a third radioone thats more finely tuned to pick up the fobs signal than the actual intended receiverand records the users wireless code. When that first signal is jammed and fails to unlock the door, the user naturally tries pressing the button again. On that second press, the RollJam is programmed to again jam the signal and record that second code, but also to simultaneously broadcast its first code. That replayed first code unlocks the door, and the user immediately forgets about the failed key press. But the RollJam has secretly stored away a second, still-usable code. You think everything worked on the second time, and you drive home, says Kamkar. But I now have a second code, and I can use that to unlock your car. If the RollJam is attached to the car or hidden near a garage, it can repeat its jamming and interception indefinitely no matter how many times the car or garage doors owner presses the key fob, replaying one code and storing away the next one in the sequence for the attacker. Whenever the RollJams owner comes to retrieve the device, its designed to have a fresh, unused code ready for intrusion. It will always do the same thing, and always have the latest code, says Kamkar. Kamkar says hes tested the proof-of-concept device with success on on Nissan, Cadillac, Ford, Toyota, Lotus, Volkswagen, and Chrysler vehicles, as well as Cobra and Viper alarm systems and Genie and Liftmaster garage door openers.
