Probably the attack from two years ago: http://www.technologyreview.com/news/422298/car-theft-by-antenna/ http://www.technologyreview.com/news/422298/car-theft-by-ant... Essentially, with the newer cars keyless entry cars, it's the car that transmits the signal to the fob (so you can't get stranded with a flat battery). The protocol itself is secure, but open to a MITM attack. The exploit works essentially like a WiFi booster. Perp #1 places himself near the car, receiving the car's transmission. This is relayed to perp #2, who is near the owner (and the key). The key communicates with the car (via the relay) - the door opens, the car starts, and off you go.
