🎃 HALLOWEENCTF@UHS-CS-CLUB

Welcome to the UHS CS Club 2025 Halloween CTF Event!

This is a beginner-friendly Capture The Flag challenge where you've been trapped in a sinister mansion. You must escape before dawn by unlocking 4 locks and solving puzzles along the way!

🚀 How to Run

Step 1: Make sure Python is installed

• You need Python 3.x on your computer
• Test if it's installed by opening Command Prompt (Windows) or Terminal (Mac/Linux) and typing:

  python --version

  or

  python3 --version

Step 2: Download the files

• Make sure all .py files are in the same folder

Step 3: Navigate to the folder

• Open Command Prompt or Terminal
• Use cd to go to the folder with the files:

  cd path/to/your/folder

Step 4: Run the program

python console.py

If that doesn't work, try:

python3 console.py

🎯 Your Mission

You need to unlock 4 locks to escape the mansion:

1. Choose a lock (1-4) when prompted by the MOS system
2. Figure out the password for that lock
3. Get the lock code after entering the correct password
4. Repeat for all 4 locks to collect all codes
5. Escape!

💡 Tips for Success

• Read the code super thoroughly! - Open the .py files in a text editor
• Google is your friend - Look up things like "base64 decoder" or "python functions"
• Look for hints in comments - The code has helpful comments from the character's perspective
• Take notes - Write down lock codes as you find them
• Start with Lock 1 - It's the easiest and builds up from there
• Think outside the box - Not everything works as expected...
• Errors can be useful - Sometimes breaking things is part of the solution 😉

📚 What You'll Learn

• Reading and understanding Python code
• Base64 encoding/decoding
• String manipulation and algorithms
• Buffer overflow concepts (simulated safely)
• Basic reverse engineering techniques

⚠️ Rules

• ❌ You CANNOT modify the code AT ALL!!!
• ❌ ABSOLUTELY NO USE of a debugger!!!
• ✅ If you are REALLY stuck, ask your peers or an exec for help!
• ✅ You CAN use online tools and Google searches

🆘 Getting Stuck?

Don't worry! This is designed for beginners. If you're stuck:

1. Re-read the code comments carefully
2. Try Googling unfamiliar terms or functions
3. Ask a friend or exec for a hint
4. Remember: sometimes the answer is right in front of you!
