Developers are fond of claiming that certain hacks are child’s play, but it happens not so often that they are really children’s toys. An American did it, to garage doors within ten seconds to open. The hack has a Dutch touch.
The used toy is a little machine to be able to chat, IM ME of toy manufacturer Mattel. The researcher, Samy Kamkar, is applying the toy in such a way that it is automatically the most common frequencies for garage door goes off.
Many garage doors operate according to Kamkar with a code of twelve bits. Because the doors all the possible input scanning for the correct code, it is brutal forcen relatively easy. For example, if you have a code thirteen-bit send, he checks automatically all the possible combinations in which thirteen bits of eight, nine, ten, eleven, and twelve bits in it.
Because he is at the check, not the whole code ‘throw away’ but simply a bit shifting, so the number of codes needed for the brute force limit by all possible codes in as short a time as possible great code to send. Because the codes can overlap, it will cost less bits and therefore less time to get the garage door to open.
Moreover, the algorithm of the Dutchman Nicolaas Govert de Bruijn, mathematician who some years ago died. Thanks to the algorithm can be Kamkar all possible codes send within a little more than eight seconds, making it the code of all garage doors that work in this way in which time can crack.
Kamkar is not unknown in the hackerswereld. Previously he was, for example, a device in an adapter for the keyboard to be able to listen.
