New Cars Vulnerable To Wireless Theft 280
tkrotchko writes "In a story published by Technology Review, researchers have demonstrated multiple times that they can bypass the security of wireless entry and ignition systems to take a car without the owner's permission. As researchers in the article point out, car security systems will begin have a real impact to every day use if a thief can simply walk up to your car and drive it away. Although this article is light on technical details, a companion article shows how the researchers accomplished the security bypass. An interesting read, and certainly something that will no doubt be the subject of a new movie any day now."

And you would be completely, 100% wrong.
The keys rely on proximity. What the "attackers" did was to provide a boost to the signals sent out by the car, causing the key to respond at much larger distances from the car than normal. The near-proximity requirement only works one way (from the car to the key), so the key will respond to the boosted signals and the car will pick up the reply if the key is within 100 meters. This attack would allow a key inside a house to unlock and start a car on the driveway.
