Remote keyless entry was once a luxury, but today it's rare to find a car that doesn't have it. Given that it's everywhere, you would expect that any possible kinks have been worked out, but you'd be wrong.
In fact, a popular model of keyless entry that uses a Megamos Crypto transponder turns out to be not as secure as car makers thought. It leaves Volkswagen, Audi, Fiat, Honda, Volvo, Porsche, Bentley and other cars brands vulnerable to thieves. But that's not the worst part.
Back in 2012, researchers at Radboud University in the Netherlands and the University of Birmingham spotted the security flaws and quickly let Megamos Crypto know. Then in 2013, the researchers told Volkswagen.
Instead of fixing the problem, Volkswagen filed an injunction to keep the researchers from publishing their findings. It took two years for the report to become public, and even now VW isn't admitting anything is wrong.
At this point, there's no way to tell which cars are affected, or if any criminals are exploiting the flaw to break into them. Of course, it seems like car thieves don't really need the help right now.
In the last few months, we've learned that a $32 gadget can open just about any car or garage door, flaws in Chrysler-Fiat entertainment systems could let a hacker take control of your car, cars with OnStar can be remotely hijacked and other car hacks will probably appear on a regular basis until manufacturers start taking security seriously.
