I was lucky enough to get to compete in the Northsec CTF this weekend with the cold_root team. We ended up placing 4th out of 88 teams. There was a ton of awesome (and maddening) challenges and plenty of Malört consumed. The challenges showed up on a fantasy themed forum: Scammed Again The first thing I did was go to the web page to find that it was a chat dialogue with an enchanter named….
Overview I recently took part in the Adversary Quest CTF. I utimately got stopped at 5/12 challenges. Thanks to CrowdStrike for an awesome CTF and I look forward to completing it next year. Below are writeups for some of the challenges I was able to complete. I'm excluding The Proclamation from a writeup as this was my solution- this was a very cool challenge so I'm going to refer you to @Vinopaljiri's excellent writeup.
As part of the Emacs minor mode I'm working on I've created a useful function to turn json into Org tables while maintaining the linkage of nested structures. The is cleverly named json-to-org-table. Why? Json is a great format for programming and parsing structures but a less good language for human consumption.

I recently got the question- "What is the use case for elfeed?". When I get a chance to talk about my favorite software I will NEVER pass up that opportunity. Elfeed is a RSS feed reader for Emacs that I use daily and it solves a lot of problems for me. To understand how this works let's start by looking at a snippet of my feeds config. Elfeed feeds is just a list of lists where each feed is represented by (url tag1 tag2 tagN) .
