LevelupCTF is a seven flag CTF. It contains vulnerabilities from information disclosures to Remote Code execution. Each flag provides hints towards the next flag. The CTF consists of wide range of challenges which provides great learning as well. Below are the vulnerabilities and their impacts that I have found: Sensitive Data Exposure – P4 Broken…
OVERTHEWIRE NATAS level 17-18 is about blind sql injection. To make the level more complicated, the output hasn’t been displayed. Let’s dive in the level: If you look at the code below. It is a simple code which takes the username and check for its existence in the table users. but No output display! This…
The walkthrough for the last level is available on this link: http://www.anonhack.in/2018/09/overthewire-natas-series-15-16-level-walkthrough/ This level is little bit similar to the last level. Here we have to perform a command injection. Let’s have a look at the source code of this level: See the highlighted text in the code above. $key variable is the one carrying our…
If you want to see the level 14- 15, follow this link: http://www.anonhack.in/2018/09/overthewire-natas-series-14-15-levels/ Level 15-16 is also based on SQL injection but here we have to work on boolean based SQL injection technique. Let me how you how: This is what the screen looks like: I put “natas16” as the user here and it turns out…

This article will guide you to use paramiko library in Python to create an SSH bruteforcing Script. This script is similar to the script we have made on PXSSH, in case you haven’t seen that post, here is the link: http://www.anonhack.in/2018/06/hacking-with-python-series-ssh-bruteforcing-script-using-pxssh/ If you want to see the usage of paramiko before going through the below…
This is a guide about how you can create SSH bruteforcing script using python. With this script you can bruteforce the username and password for SSH protocol. Below is the requirement and explanation to create this script. Library used: PXSSH Operating System: Kali [ The above library is not meant for windows ] You can…
The pxssh library is a part of pexpect package in python. Pxssh library provides you the way to connect as SSH client to SSH enabled servers, it handles the keys itself, so you don’t need to specially specify any line of code for it. I find it quite easier for making bruteforcing script via this…
