Keyless entry pwned! Researchers say it takes less than an hour
We all take for granted that the little plastic key fob in our pockets is a secure way of locking and unlocking our car doors. But a group of researchers say they have devised a way to relatively quickly decipher your car’s unique code and totally pwn everything inside it.
The group says most car manufacturers are still using KeeLoq, an encryption technology developed in the 1980s, for their keyless systems. It’s pretty good technology, they say, that normally would take 100 computers several decades to break. But by listening in to communication between key fobs and cars, the researchers say they can narrow down the number of code options and, instead of say, 50 years, they’re in your car in about 50 minutes.
While they admit it’s much easier and quicker to break into a single car with an old-fashioned baseball bat, their new, high-tech method has one merry advantage. They lay out a scenario of a packed holiday-shopping-season parking lot. Parked in the center, a van full of snooping equipment and computers listens to hundreds of keyfobs wirelessly locking car doors. Then, with little more than a few keystrokes and an hour or so later, the crooks sing “Jingle Bells” to the tune of hundreds of car doors opening in harmony.
The group claims its intentions aren’t to ruin everybody’s Christmas morning, but instead hopes car manufacturers wake up and update their 20-year-old technology. So this holiday season, remember to keep your valuables and packages hidden well, and lock your cars’ doors the old-fashioned way.
The research group’s short press release is available after the jump.

It’s no secret that Volvo has had an “FOR SALE” sign posted at the front door for some time now, but the number of bidders actually interested in the company are fast diminishing. The latest company to declare its non-interest is Renault, whose CEO Carlos Ghosn claimed that they were not interested in adding another brand to the stable.
