There's a project on github for just that kind of thing: https://github.com/DanMcInerney/wifijammer Regardless of the hardware you choose to use, however, keep in mind that you're going to be using a much higher fraction of the radio amplifier in the wifi adapter's time than normal use, so there will be proportionally greater power consumption. (Radio theory isn't really infosec, but is a design consideration for something like this; I can talk about it out-of-band if you need to know) On 07/16/2014 02:26 AM, Keira Cran wrote:
Hey, It's great that companies like Apple recognising the threat of tracking people via their devices wifi cards' MAC addresses, by randomising them. Naturally, I wondered i it was possible to jam the measurement beacon by spoofing tons of wifi clients. At one point in London, there was an advertising firm with tracking bins [1] and I have a nice clip of a technician looking puzzled at one beacon trying to figure out what's wrong. (Unfortunately, it's bit too close to home (literally) to share.) In the US I believe some ad "analytics" firms like SenseNetworks do something similar. [2] Consider this a call to arms then, to put those unused raspberry pies you have lying around to good use. best, keira [1] http://www.theguardian.com/world/2013/aug/12/city-london-corporation-spy-bins [2] http://sensenetworks.com/ _______________________________________________ Sent through the Full Disclosure mailing list http://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
