GSM Decoding Part 7: Extracting SMS Messages With 'grgsm_decode'

Ever since I associated an email address with my YouTube channel back in February of this year, I have been inundated with emails requesting help with decoding GSM data and questions about the usage of gr-gsm. So in response to this, I thought I would put together a four or five part video tutorial series on how exactly GSM cellular data is decoded in Linux with the gr-gsm software suite. Well, we're up to part 7 now and the series is going longer than expected. But the subject of the video pertains to the holy grail of GSM decoding, SMS interception. No hardware is required, excluding a working PC. Please refer to part one for a comprehensive list of the software needed for this tutorial. The only additional pieces of software needed are Wireshark and it's command-line variant, Tshark. Make sure you stick around until the end of a video for a bonus segment on getting GSMEvil2 working in DragonOS FocalX! I am uncertain if there will be part 8, as I am confident I have covered most of the important features of gr-gsm. Thanks for watching!
