This is a solution guide to the Natas4 Level at overthewire. This write-up was created on 5 March 2015.
First connect to the website
- Enter the following as the username natas4 and password Z9tkRkWmpt9Qr7XrR5jWRkgOU901swEZ
Something new this time! This time when we visit the challenge page we get the following:
Access disallowed. You are visiting from "" while authorized users should come only from (http://natas5.natas.labs.overthewire.org/
Ok, well I check the source code anyways, and nothing is really there. However, it does keep track of where I have already been when I visit the page. For example, when I refresh the page it says:
Access disallowed. You are visiting from "http://natas4.natas.labs.overthewire.org/index.php?url=http://natas5.natas.labs.overthewire.org/" while authorized users should come only from "http://natas5.natas.labs.overthewire.org/"
It just so happens that since I’m using Chrome I can use my handy dandy referrer editor. For example I changed my referrer url to “i am awesome” and it resulted in the following:
Access disallowed. You are visiting from "i am awesome" while authorized users should come only from "http://natas5.natas.labs.overthewire.org/"
Ok so enough playing around, let’s put the correct address in! Which gives us:
Access granted. The password for natas5 is iX6IOfmpN7AYOQGPwtn3fXpbaJVJcHfq
Goal! Let’s move on,
