Having fun while learning about and pivoting into the world of DFIR.

BSides NYC 0x05 hosted a few different CTFs and CTFd put a call out for volunteers to submit a few CTF Challenges. I decided to give it a shot and submitted three forensic type challenges. It was a fun experience as I have never written a CTF challenge. The CTFd people were a great bunch to work with!
Interestingly, making the challenges really helped cement some understanding of the forensic artifacts involved. It’s one thing to find and read forensic artifacts; it’s another to create or change them so they show a flag like flag{find me}. I learned a lot in the process of making the challenges.
I believe you can still find my challenges at https://bsidesnyc.ctfd.io/challenges. When I get a chance, I might throw up a repo to hold any challenges I write. The three challenges I wrote are:
They all had a Star Wars theme just for fun. The Secret Map challenges centered on a digital image and the last challenge involved Windows Notepad.
If you tried them during BSides NYC 0x05 or after, I’d love to hear your feedback.
