Detecting C2-Jittered Beacons with Frequency Analysis
Hola everyone, Today we are going to learn about Frequency Analysis using Fourier, applied to Cyber Security. This tool will allow us to find patterns within our dataset, in a much easier way than doing it in the time domain.** As last time, do not worry, I will leave a link to my GitHub at the very end under "References & More Useful Information" so you can copy everything if you want. ** Disclaimer !! Remember that the problem you are trying to solve might be slightly different than the one I am presenting, and maybe time-domain tools work best for your case. Do your own analysis before copy-pasting the code in the GitHub for optimal results. ----------------------------------------------------------------------------------------------------------------------------- Executive Summary Frequency Analysis using Fourier for Detection Engineering & Threat Hunting.
