Natas 6 -> 7

Well, it looks like we need to input a secret of some sort. If only we knew what it was... Luckily, though, someone left a link to the website source code here. And, what's this? it very conveniently says, right there:

include "includes/secret.inc";

So let's start there. That looks like a folder we could try navigating to. http://natas6.natas.labs.overthewire.org/includes/secret.inc yields the secret: FOEIUWGHFEEUHOFUOIU.

 Plugging that in gives us the password!

Natas 11 -> 12

user: natas11 pass: U82q5TCMMQ9xuFoI3dYX61s7OZD9JKoK OK, this level is a bit tricky. We start out looking at the source code, and we are faced with several functions. xor_encrypt seems to encrypt any text sent to it by xoring the input character by character with the key we want. loadData checks to see if the cookie sent with the data matches the background color, and has the 'showpassword' field in it. If the background color sent with the data and sent in the cookie match,  it stores the color and the showpassword boolean - this is probably the key to getting the key. The big trick here is that there's an XOR encryption going on. At first this might seem tricky, but on closer consideration we remember that if xor myword => cypher, then xor cypher => myword. in the function saveData, we wee that the cookie for the website is set with base64-encode, xor_encrypt, and json-encode. Therefore, we start with the cookie. We know we want to base64-decode, so let...

Natas 10 -> 11

user: natas10 pass: nOpp1igQAkUzaI1GUUjzn1bFVj7xCNzu This looks familiar - but someone got smart and decided to start sanitizing their inputs, it looks like. We can't use ;, |, or & to circumvent the grep command. Clever designers. But what other command exploits might we be able to use? Let's think back to the days when we were command-line masters instead of browser-hackers. I seem to recall that grep had some fancy functionality... like, for instance, the ability to grep over multiple files at once. So what happens if we tell it to do just that? Of course, we don't know what to tell grep to look for, so let's just use the .* operator to tell it to match any number of occurrences of anything. Remember, looking at the source, that our file will be searched over first, so we won't care too much about the massive number of dictionary words that will be spit out after. Let's try it (remember, the second file we should try looking at is the same as last ...
