You Can Hack a Children's Toy to Open Random Garage Doors

By Adam Clark Estes on at

Do you value what’s in your garage? Then you’d better make sure your garage door opener uses a secure wireless system, because it is frightfully easy to hack the more basic ones. Security researcher Samy Kamkar just proved as much when he turned an old Mattel toy into a scary universal garage door opener.

The toy in question is the discontinued IM Me, a little pocket computer that let kids chat with nearby friends. With just an open source piece of hardware and a cheap antenna, Kamkar hacked the small device so that it could crack the code of any fixed code garage door system. These are the ones that use the same code every time you press the button to open your garage door. So-called rolling code systems generate a new code every time but are also vulnerable.

“It’s a huge joke,” says Kamkar, with just a tinge of sensationalism. “The worst case scenario is that if someone wants to break into your garage, they can use a device you wouldn’t even notice in their pocket, and within seconds the garage door is open.”

That is a bad scenario! But you can protect yourself and your family by paying closer attention to the security of your garage and your home. (The above video offers some details on how.) With any luck, news of this attack will prompt the companies that make garage door openers to up their game. Because there are valuable things in your garage—not to mention to rest of your home.
