Over the wire Natas Level 4


Over the wire Natas Level 4

Objective:
Get password for Level 5

Solution:

This page just shows a text box

Access disallowed. You are visiting from "" while authorized users should come only from http://natas5.natas.labs.overthewire.org/

Ok so the message here is pointing us to the referring website.

IF we fire up burp suite and turn on intercept we can see this

And forward the intercepted traffic on

RingZero CTF - Cyrptography - You're Drunk

RingZero CTF - Cyptography - Your're Drunk Problem: Ayowe awxewr nwaalfw die tiy rgw fklf ua xgixiklrw! Tiy lew qwkxinw. Solution: So just looking at this one it looks like its formatted as a sentence. There is spacing between words, punctuation and capitalization. At fist I thought Cesar cipher, but I ran through some shifts and none of them came back with english words. So then I though substitution cipher.
