Hackers using cheap wireless devices pose a threat to millions of cars equipped with Volkswagen's keyless entry system, according to a study from the University of Birmingham. Scheduled for presentation Friday at the USENIX security conference in Austin, Texas, the study shows that thieves can use a simple wireless device to unlock the doors of millions of cars remotely, essentially by cloning the remote control that wirelessly secures a car door lock. A second hack involves recovering the cryptographic key by attacking the rolling code scheme.

Anyone with a hammer poses a threat.. they can break glass no thief is going to waste time with some expensive scanner to carry around that may or may not work.

A hammer works on EVERY car regardless and it's much easier and quicker.

Don't keep valuables in car, best advice, no need to worry about people stealing stuff if there is nothing to steal, literally.

This article is mere hype.. sure there are vulnerabilities.. but they are difficult to attain.

go read the article about how they conducted their tests, it was isolated they know the car and codes in advance (that's important), so they do these tests on the SAME vehicle over and over until they get in.. that's hardly a real world test.

Then they say the car is easy to enter, again look at the details.. *IF* you know when someone presses a button on their remote and *IF* you happen to be in the same location as that remote, and *IF* the car systems is able to respond to a foreign key with a few seconds of entry *THEN* the car can be opened by a key other than 2 the 2 that were paired with the car initially...

It's all media hype, they make it SOUND easy but it's hardly that simple.. You can take the device and walk around a VW dealership.. I DARE you to repeat their steps.. if you open 1 in 100.. yeah you would call that success, but 1 in 100?

I will take those odds.. On top of that this ONLY gains entry to the vehicle not the starter, not the trunk (that's a different key usually) or you can lock out trunk \ glove box with valet mode.. if you are paranoid just leave valet mode on.

Put valuables in the trunk.. voila. problem solved.. yeah you can climb in the back seat, lift the arm rest and wiggle your arm inside the trunk in the hopes you might something valuable that would fit in that same hole, good luck.

A thief is in and out in under 30 seconds its smash and grab, they aren't going to waste time scanning vehicles for potentials vulnerable vehicles..

besides talk to ANY master locksmith, they can use a slim jim and get in and out of ANY car in 10 seconds using a specially designed piece of metal, how do you think they can unlock your car in the first place? Yeah so this is more advance but a locksmith can break into your car..

don't get me started on the anti-theft alarm, and car start you have to bypass and lojack.. if you are REALLY concerned don't keep expensive stuff in your car, period.

Pull the fuse.. or buy a cheap car with no frills.. but it's a standard on every car now..

No need to be paranoid about something you can't control, if someone REALLY wants something in your car, they break glass, can be done in 2 seconds, steal whatever is in back seat, and run, no sense wasting time carrying around a code scanner when a rock hammer will do the job much easier...

Hmmm does this device give the "hacker" the ability to also start the engine, or just enter the vehicle?

Anyone even remember why we need remote keyless entry? Are we that lazy we can't put a key in a lock anymore? Do we have to be able to unlock our car from 20 feet? In the end technology is not always a friend but another security risk. Not to mention a annoying bulky key fob I have to deal with. Change the battery every couple years and hope I never lose it because their not cheap. I could go to my local hardware store before and for a buck or two get a copy of my key. Yea, technology is great isn't it?

Seriously? Wireless is not the problem, sure we can use a key and put in the door.... ALL 4 of them, yeah that's a terrific idea (rolling eyes).

The reason we use keyless is not merely for convenience it's for safety.. you are obviously a guy because a woman would know that they can use the key to not only unlock the door but sound an alert for one, and secondly having the door open at an instant instead of fumbling for key is WAY more secure.. so yes we NEED keyless.

Instead of just grumbling about why such a "convenience" is unnecessary do some research first.. it's quite easy to establish reasons why keyless became the standard.

I can cite more examples but you should be able to find these on your own.. I would hope.

But much of this wireless technology is poorly done and so its no better than traditional keys. Stop defending a wireless technology that's easily cracked.
