![]() "The industry is aware that the complexity and cost associated with mounting a relay attack has dropped over recent years," says NXP spokesperson Birgit Ahlborn. They also emphasized that NXP likely isn't alone in leaving vehicles vulnerable to the attack. They point instead to NXP, the Dutch chipmaker that builds the keyless entry system used in the Qing, Captiva and dozens of other vehicles. But the researchers emphasized that the problem reaches further than the two vehicles they tested. In their tests, the Qihoo researchers say they were able to remotely open the doors and drive off with two vehicles: A Qing gas-electric hybrid sedan from the Chinese automaker BYD and a Chevrolet Captiva SUV. Then they immediately transmit the key's response back along the chain, effectively telling the car that the key is in the driver's hand. Rather than try to crack that radio code, the hacker's devices instead copy it, then transmit it via radio from one of the hackers' devices to the other, and then to the key. That elicits a radio signal from the car's keyless entry system, which seeks a certain signal back from the key before it will open. The device near the car spoofs a signal from the key. One hacker holds a device a few feet from the victim's key, while a thief holds the other near the target car. The attack essentially tricks both the car and real key into thinking they're in close proximity. The Qihoo researchers, who recently showed their results at Amsterdam's Hack in the Box conference, say their upgrade also significantly multiplies the radio attack's range, allowing them to steal cars parked more than a thousand feet away from the owner's key fob. That's far cheaper than previous versions of the key-spoofing hardware. Now a team of Chinese researchers has not only demonstrated the attack again but also made it cheaper and easier than ever.Ī group of researchers at the Beijing-based security firm Qihoo 360 recently pulled off the so-called relay hack with a pair of gadgets they built for just $22. ![]() But even after repeated demonstrations-and real thefts-the technique still works on a number of models. The signal should appear “L” shaped when viewed by the drivers behind you.For years, automakers and hackers have known about a clever attack that spoofs the signal from a wireless car key fob to open a vehicle's doors, and even drive it away. ![]() To signal a right turn, extend your left arm out of the left window and bend it at a 90-degree angle with the hand pointing upwards. Attempting to lean over to the right window would impair your control of the vehicle and view of the road ahead. Hand signal for right turnĪs you will only have safe access to the left window, both left and right turns must be signaled from this position. As a motorist, you must understand these signals. Without electronic signaling devices, cyclists must always rely on hand signals to communicate their intentions to other road users. It is possible that other drivers will use hand signals if their indicators are broken, though you are more likely to encounter cyclists using them. You will need to recognize other road user’s hand signals far more often than you will need to use them yourself. Most drivers assume that remembering hand signals will only be necessary in the unlikely event that their turn indicators fail, but this is not the case.
