*WiFi Tracking*

Tracking people using 802.11 probe requests has been well known for some time, so long in fact that many major manufacturers of mobile devices no longer transmit probe requests and rather wait for the Wi-Fi access point to transmit its beacon.

It also relies on accurate Wi-Fi access point location information to be made available on sites like WiGLE.

In my experience, locating people using just probe requests is very hit-and-miss. If you're concerned about this, my recommendation to use a "generic" Wi-Fi access point name for your home Wi-Fi such as "Home". According to WiGLE the most common SSID names (worldwide) are:

1. xfinitywifi
2. linksys
3. BTWiFi-with-FON
4. <no SSID>
5. BTWifi-X
6. XFINITY
7. UPC Wi-Free
8. AndroidAP
9. Ziggo
10. NETGEAR

I suspect many of these are based on local service providers in the US, so probably not a great idea to use them in other countries.

True.

Yes it's well know of course,but i did these apps for more details.
Wigle was not enough accurate for this project,i used another private database for this.

Also i was looking for a mobile solution,so you don't have to stay at home to track probe requests,but you can track them anywhere.

At this time many mobile manufacturers still sending probe requests of what i saw.. but they can also send random probe requests to avoid tracking.

Some years ago I made a concept system. It was using several wifi devices, in promiscuous mode, listening to traffic. The system had a dozen nodes, placed in a grid, reporting RSSI values. It was able to do tracking of people down to 1-2m accuracy. So if they put it in a shop, together with cameras, and recipes, they would get very accurate information about your shopping habits. How much time you spent thinking which chips to buy. Did you go for your favourite beer right away, or did you stop to look for alternatives.

With the new remotely update-able price tags they can increase the price of everything after 18:00, when all the busy, working people shop, and reduce it at 10:00 when all the retirees are buying. It was discussed to place BLE beacons into each shopping cart as well.

Welcome to the new world, where we know more about you than yourself.

I love the "grid" concept.
It could open the way to many investigations....for sure our devices are constantly sending informations without our knowledge.

I'll post later another concept about wifi(scanner,sniffer,custom captive portal,honeypot) and all this in a single tiny module.

I have been using WiFi Analyzer for a long time now for setting up networks.
No special hardware required for Andriod phone.

Hello Community,



Staff: If i'm not in right section sorry and could you move it please

I'm starting to wonder if your on the wrong forum site. We don't do illegal stuff here!

[I wanted a rude username]

What OP is doing doesn't seem illegal. All the intercepted packets are being willingly broadcast, in plaintext, on a public band, by various devices. But I'm not familiar with French law.

Right. Receiving radio broadcasts is legal in most countries.

I checked the Google Play store and found several apps called 'WiFi Analyzer', could you be more specific?  Would like this functionality on my phone too... thanks.

The open source one, com.vrem.wifianalyzer

I get it from F-Droid, but it's on Google Play as well.

And yeah, it's the bee's knees.

In light of another topic i deleted for being covertly illegal I got a bad vibe about anything the OP posts....
