Hello CTM Applicants!!
This Repository contains the Design Assignment and challenges of CTM selection for 2025-26. Each of them is in a seperate directory.
For each challenge (unless otherwise stated). Your goal is to find a "flag" from the files provided, look at the readme file to get yourself started. You will also be required to provide a write-up for each challenge.
For challenges that you solve it will be sufficient to explain the method by which you solve them and provide any scripts/payloads you may have written to solve the challenge.
For challenges you are unable to solve your writeup should contain all the approaches you tried. Selection is not based on just finding the correct flag, we also want to see your thinking hence the writeups are crucial.
Here is the submission form
To submit create a google drive folder with appropriate sub-directories for each of the challenges. If there's a flag have it in a file called flag.txt also include a writeup in the directory. You will have to submit a link with the drive folder. (Don't forget to set visibility to anyone with link!)
To be considered for the position of CTM it is mandatory to submit the design assignment and writeups for each challenge. (Even if you are unable to solve the challenge).
