OverTheWire Natas Level 0 Walkthrough

Today we're starting a series of CTF wargame walkthroughs featuring the Natas series from overthewire.org .  The levels in this series cover a lot of different web-based enumeration and exploitation techniques, and going through them will help sharpen our skills.

Each level in Natas requires you to navigate to a specific webpage and authenticate into it using the credentials captured from the previous level.

In the case of Natas level 0, we navigate to this page:

http://natas0.natas.labs.overthewire.org/

At which point we are greeting with the authentication prompt.


Here we provide natas0 as both the username and password, which leads us to the actual webpage, where we are presented with the following message:


As there is nothing else useful on the webpage, we want to look at the webpage source to see if there's anything there.  We can either right click on the page and select View Page Source or we can use the keyboard shortcut, which is Ctrl - u (using Firefox browser).  Doing so, we see this:



It's always a good practice to look at the webpage source when we're doing web-based enumeration, and so we have the password for level 1 of Natas.  It may be useful to you to keep a collection of the passwords you've collected in a separate file for reference.

Summary

Natas level 0 required us to inspect the webpage's source to locate the password for the next level.

Finish
