CTF Challenges - April 2026 Event
Most of you have seen my posts on either the Basement or DarkForce about the challenges I developed for the upcoming CTF (capture the Flag) we are hosting for our students. I thought I would share them here, to give you more than what I can put on the BBS.
If you want any hints for any of the posted challenges, drop me a message and I will send one. There are at least ONE hint per challenge, but it will cost you in points. :)
The first one I will share is "The Digital Dead Drop"
Description: We intercepted a suspicious image file circulating on a local USB drive. On the surface, it looks like a completely standard photograph, but our analysts suspect it is being used to smuggle data past the perimeter firewall.
You do not need to crack complex encryption or reverse-engineer advanced cryptography for this one. You just need to look beneath the surface. Use your basic command-line forensic tools to examine the file's internal structure and extract the hidden message.
Rumor has it the smugglers hid a crucial piece of intelligence in this file that might help you bypass the physical NFC security systems later.
Points: 50
