 For my video project, one of the demonstrations included using an Ubertooth One to scan for Bluetooth and BLE packets. This blog post will cover the installation of the Ubertooth One on the Mac mini M1. The official install guide for Mac devices didn't work very well for me, and I had to install some extra tools in order to get it to work. The examples assume you are using Python 3, and have homebrew installed.  To begin, follow the instructions found here:  https://github.com/greatscottgadgets/ubertooth/wiki/Build-Guide . Additionally, you may find that you need to install pytq5, numpy, and qtpy. To do this, simply run Python3 pip install pyqt5, numpy, qtpy. This will install the required libraries needed to run the Ubertooth tools. There are multiple ways to install pip on an OS X device, but I suggest using homebrew to install python3, which should install pip as well. Next, you will need to update the firmware of the device. When downloading the tools, a firmware di...

 My plan for this week was to go over and talk about IP headers and datagrams. However, while looking through some resources, I find a document that can explain it far better than I can. So instead of diving into the technical nitty-gritty of packets and headers, I'll let Burton Rosenberg of the University of Miami's Computer Science departmen t handy article explain it.  With my original plans for this article taken care of, I instead thought that it would be a good idea to cover how to actually examine a packet and apply this information. It is one thing to know the theory, and another entirely to apply it. With that in mind, I decided to play around with Wireshark and throw together a little demonstration depicting the process.  This is a Wireshark window that shows the HTTP traffic to and from my VM. To generate this information, I started Wireshark, confirmed in the capture options that it was using the correct adapter, and performed a google search. The packet that ...
