ISSessions CTF 2024

The Second CTF I competed in this year was decently successful. This CTF was put on by a club at Sheridan College for students throughout Canada. 46 Canadian teams were competing with anywhere from 1 to 4 people. I paired up with another peer to have a team of two called "ICUP-905," akin to "I See Your Ping." We tied for 5th place with the completion of a final challenge in the final moments before the end, and I placed 11th overall.

I made these as different posts, and with the additional content, it became a very long page, and I wanted to break it up.   Only the Challenges I had a part in solving are documented here, which is why you will notice some blacked out.  This represents the "Other Challenges."

Review

Going through my documentation and “parsing” through my notes is always a fun time for a CTF. I have tried to do this over the last few CTFs after seeing similar challenges, but I also want to expand on things I may not know or places I messed up to help improve my efficiencies.

First, though, I would like to thank my team member from school Purvam.  In the end, due to others' obligations, it ended up being a team of two, and I felt like we did an amazing job.  We worked off each other’s strengths and helped bounce ideas for challenges. I think what's important to note for all, though, is that CTF challenges are exactly those challenges. They are made to test your thinking, and you don’t always have to solve every challenge. However, just attempting one is the first start, and seeing where your strengths and weaknesses lie.  If you don’t know something, do a search, look at old Challenges, and practice. And in the end, it’s always said just because you aren’t great at a CTF doesn’t mean you wouldn’t be good at Security. It’s no different than other puzzles, just with security twists.  All in all, the team at Sheridan College did a fantastic job.
