/DayOfTheDoctor0x1-CTF

This is a reverse-engineering challenging involving a Linux binary file coded in C. Was my first time making a challenge like this, best of luck!

Day of The Doctor0x1 CTF Challenge

This will be my first attempt at making a semi-decent CTF challenge. It should not be that difficult, but I hope you enjoy it.

If you have feedback, you can find me in the Hack Nexus Discord Server

Challenge

Running the binary will present you with a "flag" that isn't quite a flag. The rest is up to you.

You are free to run the binary through VirusTotal or anything you like to check if it's malicious.

I will be updating this repository with the uncompiled challenge file when this challenge is solved for the first time.

Getting Started

Precompiled Binaries

This repository contains a single precompiled binary that can be run on a Linux system. I recommend using WSL or Hyper-V with a Linux VM to solve this.

  • Linux (x86_64): day_of_the_doctor0x1_linux_x86_64

Challenge Rules

  1. DO NOT share the solution publicly.
  2. You may use any tools or techniques to investigate the binary.
  3. The flag format is: flag{...}.
  4. Have fun, and let me know what you think afterwards.

Tools You May Need

Feedback

Good luck, and may the things you've learned in Hack Nexus help guide you to the flag.
