Passive WiFi Tracking Posted February 26, 2014 by Edward Borrowed from: http://edwardkeeble.com/2014/02/passive-wifi-tracking/

In the last year or so, there have been quite a few stories on the use of passive WiFi tracking by advertisers, retailers, and analytics startups. Most of these articles focus on the significant privacy and security concerns associated with this practice, but few of them get into the details of how the technology works. Having built a similar system for my project, Casual Encounters, I think I can explain some of the inner workings of these systems, how to avoid being tracked, and how, for research purposes or to determine their own level of exposure, someone could build such a system. I will state that I am by no means an expert on wireless networks, signal analysis, or anything of the sort, but I have conducted a fair bit of research and trial and error, and it works for me. Your mileage may vary; don’t try this at home; etc, etc.

Preface

So in the past, I've used MAMP/MAMP Pro apps and others alike. I've also, setup my own local MAMP stack with homebrew, that used dnsmasq to dynamically add vhosts anytime I added a new folder to the Sites folder which made it very convenient. But, then I started running into other environment issues with PHP versions on remote machines/servers not being updated or some other crazy thingamabob breaking. I researched and invested time in Vagrant, but that seem to break more often than my homebrew setup. So I researched again investing time into Docker via Docker for Mac (which is BAMF), which I'm sold on and use daily, but it still seems a little bleeding edge and not so simple to wrap your head around the concept. Not to mention I don't have a real use case to play with and take advantage of all the features that come packed with Docker.

This is the beginning of trying to find something more simple, and slightly quicker to setup.

The Virginia State Corporation Commission (SCC) charges for bulk data of corporate registrations—$150/month for weekly updates, with a minimum three-month contract. I asked them for a list of their customers for this service. They are as follows:
