The easiest way in Linux to check if a device has the RFMON/Monitor mode capability is to run: Two WiFi chips gets me around this problem, but if it's on-hand then a regular Ethernet cable does the same job. You can absorb traffic, but you can't transmit. This is because when you enter Monitor mode on a wireless device it kills any and all connections and the ability to use traditional Access Points. I also have a USB wifi dongle which is what I actually use for scanning since the chip supports it, but also because it allows me to browse the internet and scan at the same time.

Fortunately, my on-board Intel wireless chip does support it and the Linux Kernel drivers support interacting in this methodology. Unfortunately, it is not always possible to enable the Monitor Mode on a wireless device, often due to the OS drivers for a particular device not supporting it. For interest the others are Master, Managed, Ad Hoc, Mesh, Repeater and Promiscuous. Monitor mode is one of seven modes that the IEEE 802.11 specification allows devices to operate in. It is differentiated to the more commonly known promiscuous mode in that in addition to regular packet-sniffing, an assocation with an Access Point or Point-to-Point network is not required. 'RFMON' allows a computer with a wireless network interface controller to monitor all traffic received from adjacent wireless access points and client devices.

I only know how to do this on Linux systems although there may well be Mac and Windows tools I don't know about.
How is the Data Acquired (tell me how you do this)?Īcquiring this data is ridiculously easy (it's flying all around you for a start.). I also had to run a Security event stand for prospective Degree Apprentices and thought it would be highly engaging and interactive if I were able to show some that their phone gave away information about them. This is BAD from a security perspective, which is why I find it really interesting, and this will be explained shortly.Īdditionally, I had a genuine interest in this subject. If you believe you know someone's phone via MAC Address, you can see their past advertised networks and use a tool like Wigle to see where that network has been recorded in the real world. That is what I am interested in, as not only can you 'fingerprint' someone by their unique list of 'advertised' saved networks their phone progressively iterates through broadcasting, you can see where they've been in the real world. When your device has WiFi enabled but is not connected to an Access Point it sends out probe requests, sometimes Broadcasts (to 'anyone' who is an access point to respond to), but other times it will explicitly list the name of the network it wishes to connect to.

Take a look now on your Android or iOS phone, the list is usually in the WiFi settings somewhere. Most people then forget this and build up a massive list of 'Saved Networks'.
However, the 802.11 specification (.WiFi) also allows personal devices to send out 'Probe Requests' blindly around them in the hope that a nearby familiar access point will realise "Hey, that's me! I better Beacon again myself so that device can see me and then elect to connect to me".īut what is a 'familiar access point'? Well, every time you add a new WiFi network to your phone, you essentially add it to your 'favourites'.
Most of the packets flying around which govern Access-Point-to-Client connectivity do indeed originate from the Access Points. When device's see a familiar SSID they join, right? Most people have a misconception about WiFi and assume that the Access Points are always broadcasting somehow to make themselves visible to devices.
