Hack opens garage doors using toys and algorithm Dutchman
Developers may like to claim that certain hacks are child’s play, but it does not happen so often that they use real toys. An American did, to open garage doors within ten seconds. The hack has a Dutch touch.
The children used a little machine to chat, an IM-ME toy manufacturer Mattel. The researcher, Samy Kamkar, the toy to fit so that it triggers the most frequencies used for garage doors.
Many garage doors operate according Kamkar with a twelve-bit code. Because the doors to scan all possible inputs at the right code, the brute Forcen is relatively easy. For example if you send a thirteen-bit code, it automatically checks all possible combinations in which thirteen bits of eight, nine, ten, eleven and twelve bits in it.
Because he is not the whole code ‘discard’ but simply moves a bit, you can so the number of codes needed to limit the brute force by sending all the possible codes in the shortest possible large code at the check. Because the codes may overlap, it takes fewer bits and less time to open the garage door.
In addition, the algorithm of the Dutchman Nicolaas Govert de Bruijn, a mathematician who died several years ago. Thanks to its algorithm Kamkar can send all possible codes in just over eight seconds, making him the code of all garage doors work this way can crack during that time.
Kamkar is well known in the hacker world. Previously, made he a device in an adapter to eavesdrop keystrokes.Viewing:-201
