In many countries, private garage, except motor vehicles, kept a large number of different kinds of things of some value. However, many automatic garage doors are protected only by the code, though very simple. Information Security Specialist Samy Kamkar (Samy Kamkar) opens these doors without any problems using a child's toy.

His instrument Kamkar called OpenSesame, and this tool is able to open almost any automatic garage door system which uses a "fixed code". Toy - IM-ME from the company Mattel, with an additional antenna and the open-source code, written by Samy. It turns out that this device can try out all the available combinations of code in a few seconds.

According to Sami, the attackers at any time can open any garage, using a toy that fits in your pocket. It is worth noting that hacking is only possible with the system, which uses the same code to communicate with the remote control. There are other options for garage doors where the code changes each time the button is pressed, pula. Who is difficult to determine which of garage doors - fixed code, in which - changing, dynamic.

However, the garage door itself Kamkara be vulnerable to such attacks. System has been activated, and when checking the automatic control garage door two friends "cracker." And in fact, and in another case, the company was a manufacturer of Linear, a subsidiary of Nortek.
