Capturing Roaming Events

Image
Finally! I scored a newer laptop to put Kali Linux on along with Windows to do some more wifi shenanigans. Before I was using a WLANPi on my desktop, which limited my mobility of course. Now I can follow devices and get closer to some of my other APs. Yes I know you can also use Pi as a remote capture device but that still didnt help with looking into roaming events. Now its been a few years since Ive used Kali and I was amazed at how polished its become. I think I used Backtrack about a decade ago to try and 'hack' my wifi with a WPA cracking tool. Needless to say that didnt launch my security career but it was quite interesting. There are plenty of tutorials on how to set you capture device in monitor mode so I wont go into that here. If you are curious here is the Airmon-ng website. Please note only certain chipsets are supported in Kali for this. Atheros cards seem to be the defacto standard for monitor mode support but I had a Comfast CF912 and TPLink Archer T9UH adapter ...

802.1X Easy

Image
  802.1X Easy Updated 3/19/2025 It seems I like doing things the hard way sometimes. Packetfence was that next thing. After much trial and error I fell back to something simpler that I already had running. OPNSense with FreeRADIUS. My goal is to create a wifi lab that utilizes Dot1X to better understand how enterprise wifi works. While my day job does allow me troubleshoot it, I cant easily test and play around with it. My setup is basic but that's what makes this so great and accessible for people without the space or extra money for power hungry devices. An OPNSense VM running on Proxmox (Or a standalone device) A Cisco 3560 desktop style gigabit POE switch 2 Unifi AP AC Lites And that's really all you need. You could even go a little cheaper with a basic POE switch if you don't plan on doing wired Dot1X. Once your OPNSense instance is setup you just need to download the FreeRADIUS plugin then you can begin configuring Dot1X. Configuration You'll want to crea...

IoT and Smart Home Devices: Part 1

Image
  Source: https://www.sparkfun.com/products/17146                 This is going to be a multi part post going over a little IoT smart plug I picked up on clearance at Walmart. I'll make it clear I'm generally very skeptical about these types of devices so much that I don’t even want my roommates Alexa on the same network as mine. However with these things being so prolific it is best to understand them so we can better protect our networks. Ill start with a little background of the device, how I acquired it, and my research on the brand. I will then do my best to uncover any (hopefully) FCC filings and their documentation. From there we will explore a bit of the theory on how the majority of these cheaper devices connect to our networks. Lastly Ill do my best to capture packets during the join process but we will see how that goes with my limited setup.  I was looking to purchase a new Roku and since Walmart was the closest st...
