How to Write a Good CTF Writeup

Hi everyone! This is an example writeup to show you the structure we're looking for when you submit yours to the HackDev MY site.

1. Challenge Info

State the challenge name, category (web/pwn/crypto/forensics/etc.), and point value. If it's from a specific CTF, name it.

2. Recon / Initial Approach

What did you see first? Include screenshots, nc output, source code snippets — whatever you were handed at the start.

##3. The Process

Walk through your actual thought process, not just the final answer. Include:

• What you tried that didn't work (this is often the most useful part for readers).
• Tools/commands you used, with exact syntax.
• Any "aha" moment that unblocked you.

4. The Solution

The final exploit/script/payload that got the flag. Fenced code blocks, please.

5. Flag

This is an example of a flag: flag{example_flag_here}

6. Takeaways

One or two lines on what you learned or what pattern to watch for next time.

Tips

You can import your image as your proof of working by clicking the "insert image" button on top right.

For example, this is my desktop background:

You can import multiple photos. Also, please keep in mind that this is in markdown format! so you can even put a link!

Submit yours through this form, even "I didn't solve it but here's how far I got" writeups are welcome.
