Hot on the heels of the previous CyberDefenders Challenge Solution comes this noisy installment which solves their Acoustic challenge. You can find the source Rmd on GitHub, but I’m also testing the limits of WP’s markdown rendering and putting it in-stream as well. No longer book expository this time since much of the setup/explanatory bits… Continue reading
Packet Maze: Solving a CyberDefenders PCAP Puzzle with R, Zeek, and tshark
It was a rainy weekend in southern Maine and I really didn’t feel like doing chores, so I was skimming through RSS feeds and noticed a link to a PacketMaze challenge in the latest This Week In 4n6.

After a fairly hectic set of days since said NOTE came, I had time this morning to poke at a fix. There are alot… Continue reading
Using the new Plot Javascript Exploratory Visualization Library Sans-Observable
The fine folks over at @ObservableHQ released a new javascript exploratory visualization library called Plot last week with great fanfare. It was primarily designed to be used in Observable notebooks and I quickly tested it out there (you can find them at my Observable landing page: https://observablehq.com/@hrbrmstr). {Plot} doesn’t require Observable, however, and I threw… Continue reading

The full… Continue reading
