However, the attack requires correctly guessing the real MAC address of the device - a brute force attempt across the entire 2 48 address space is not feasible to count devices at a conference. Recently, an interesting paper emerged from the Naval Academy showing how MAC randomization can be defeated due to a hardware layer flaw. A device using MAC randomization will quickly fill a probe request sniffer with false positives. MAC randomization prevents probe request tracking by sending a random MAC address with each probe request packet.

Apple introduced MAC randomization in iOS 8) and it was introduced into Android with the 6.0 Marshmallow) release.
Retail stores used the unique MAC address to track customers across multiple visits and the TfL tracked passengers' movements throughout the London Tube.įortunately Unfortunately, it's not as easy to track devices as it once was. Every Wi-Fi chipset has a unique MAC address that is sent with the probe request. If a device is not currently associated with a wireless access point it will probe for all known networks with a probe request packet. On the surface, tracking devices via Wi-Fi is very straightforward. from being used to launch scripts at boot. Also, Raspbian uses systemd, so systemd is used in this tutorial but there is nothing preventing runit, sysv, upstart, etc. In fact, the lack of a Real Time Clock ( RTC) on the Raspberry Pi made the task a little more challenging. I picked a Pi because I had one on hand and I didn't particularly care if it was lost/stolen/broken at the conference. ARM development boards, laptops, some Android phones, desktops, etc. In a nutshell, a Raspberry Pi with a wireless dongle operating in promiscuous mode tracked particular 802.11 packets via tcpdump and unique MAC addresses were logged and used as a proxy for visitors.īefore I get into the details of this project, I have to say that it is possible to use nearly anything running Linux with a promiscuous-capable Wi-Fi chipset. Luckily, it was safe to assume most of our visitors were carrying a smartphone so it was feasible to track Wi-Fi beacons. Rather than use a tedious mechanical clicker to count guests, I set out to create an automated method. C:\>python > from scapy.all import * > ip = IP () > ip.I was recently a vendor at a large conference and was tasked with keeping track of how many interactions we had at the booth.
The following lines will actually import all scapy modules, functions and variables, then we create and show an IP packet for testing purposes. Using Interactive Shell C :\ > scapy Welcome to Scapy ( 2.4. There are two ways of running scapy, one is using the interactive shell and the second is to import it in python script.

When you finish installing these dependencies in various platforms, you can easily install scapy using the following command: In Windows, you gonna need to install npcap here. If you are a linux user, you can run scapy without libpcap, you need to install tcpdump by the following commands:įor Mac users, You may need to install libpcap first using the following commands: InstallationĪlright, enough talking, now let's dive into the installation of this amazing module.įirst you are going to need Python 2.7+/3.4+ installed, if you don't have Python yet, head to python official website.

You are free to put any value you want in any field you want of the packet you want and stack them like you want, the authors assume that you are an adult. The authors of scapy designed it to be much easier for beginners, as well as powerful tool for network analysts.Īs mentioned in the official documentation, s capy enables you to build exactly the packets you actually want. You may say now that you don't really know these tools, well if you don't, no worries. It can literally replace most of any penetration tester's favorite utilities such as tcpdump, hping, arpspoof and some parts of tshark and nmap. Well, the fact is that it provides us with a lot more functionalities than any other tool or module.
Now you're maybe wondering, ok well, but why scapy specifically ?
Install tcpdump mac portable#
It mainly provides a Python interface into libpcap, which is a portable C/C++ library for network traffic capture. So you can use nearly all of scapy's features on a Windows machine as well.
Install tcpdump mac mac os#
It runs natively on Linux (as well as Mac OS X), but the latest versions of scapy actually supports Windows out-of-the-box. Scapy is a packet manipulation tool for computer networks written in Python.
