DragonOS FocalX Cellular Security Research w/ LTESniffer (srsRan, LimeSDR, B205mini) part 1

The purpose of this video is to support security and analysis research on cellular networks. It's also created from an educational perspective to help learn more about cellular networks in general by means of a controlled lab environment and software defined radios. Privacy is respected at all times and any use of this tool or software defined radios in general is on the user to follow all local regulations.

With that said, LTESniffer is easily installed in DragonOS FocalX, in fact it can be installed with apt after setting up an install with the following PPA.

In this first video on cellular security research, I focus on the general lab environment setup in order to use the downlink functions of the tool. While it is recommended to use a B210 w/ 2 antennas, I opted to try the LimeSDR mini against a B205mini powered srsRAN network. To fill the UE role, I chose to use a PinePhone w/ programmed SIM card, although I think I failed to setup the credentials correctly to enable proper authentication on the network. (I'll fix for next time).

Regardless, I was able to show realtime decoding on the downlink and also how to setup Wireshark to look at the pcap files. I hope this video is helpful and I encourage reading over the project page and provided research papers.
