OverTheWire Natas — Complete Walkthrough Index

OverTheWire Natas — Complete Walkthrough Index

Halloo SuiiKawaii dessu!! Glad to see you again. This page is the master index for my Natas walkthroughs — actually i don’t have much to say because the title and desciption already help you figure out what is this post about so yeah today we gonna do some OverTheWire Natas 🗣️🔥🔥🔥🔥!!

Introduction

If you’re getting into cybersecurity or ethical hacking, OverTheWire (open in new tab) is one of the best beginner-friendly playgrounds for server-side web security. There’s no SSH — each level is a website at http://natasX.natas.labs.overthewire.org (X = level), logged in with the level’s username & password. :contentReference[oaicite:0]{index=0}

Natas currently spans Level 0 → Level 34. We’ll link every level below as posts go live. :contentReference[oaicite:1]{index=1}

Why play Natas?

• Hands-on web vulns from the ground up.
• Builds instincts with headers, cookies, auth, encoding.
• Touches LFI/RFI, SQLi, XSS, CSRF, uploads, regex filters, and more.
• Totally free — just a browser + network tools.

By the end you’ll be comfortable with:

• Reading/altering HTTP requests (curl, Burp, devtools).
• Inspecting source, responses, headers, cookies, sessions.
• Turning small observations into repeatable exploits.

About This Series

Each level has its own post with:

1. Login Info — how to connect for that level
2. Task — the original OTW prompt
3. Theory — short notes on the concepts
4. Solution — step-by-step, reproducible walkthrough

My goal isn’t to dump passwords but to show why each step works so you can solve similar problems on your own.

How to Play Natas (and actually learn)

1. Read the page + source carefully.
2. Try first, then peek at hints if stuck.
3. Use devtools/Burp/curl aggressively.
4. Keep a logbook of requests, payloads, dead ends.
5. Fail fast, retry until you can solve it without notes.

Pro tip: tiny, repeatable HTTP requests beat guesswork — save them and iterate.

Conclusion

There are tons of guides out there from other Blog to Youtube videos, but i made this series is my take with my own style of workflow, notes, and explanations. Even if you just skim, I hope it will helps you learn faster.

Finishing Natas feels like leveling up from “web noob” to request-slinging ninja 🥷:

• HTTP becomes a friendly toolbox.
• You can chain small tricks into real exploits.
• You can learn anything by slicing it into tiny, winnable steps.

Next adventures:

• Krypton (crypto)
• Narnia (binary exploitation)
• Labs: TryHackMe / Hack The Box

Keep playing, keep breaking (legally!), keep notes — you got this 💪

Thanks for reading!

Until next time — Otsumachi!! 💖☄️✨
