How To: Fix Kali 2016 Repository/Mirror Error

Recently, I decided to install Kali 2016 as dual boot on my laptop. Everything install perfectly up until the installer gave me the option to set up the package distribution mirror. No matter what setting I provided, no mirror would set up correctly. I was forced to continue the install without setting up the mirror. If you do not know what this means, I will explain it. Basically, you will not be able to update or install any tools onto your Kali distribution.

How To: Bypass Windows Passwords Part 2

This is the second installment of the short series on how to remove user passwords in Windows. Once again this has only been tested on Windows 7. If I can find some time between two jobs and school I'll test all the ways on Windows 10 and Windows 8/8.1.

How To: OSX VM Image Install Guide

I was on our new #nullbyte IRC channel when someone told me how tedious it is to install an OSX Virtual Machine on Virtual Box (I think it was wawa). We all know Linux rocks (gets acknowledgement from the crowd), but there are morons out there, multiplying at a never before seen rate, who use OSX. We at nullbyte should be prepared for anything and everything. So, in this guide I take you step by step to creating your OSX Yogemite VM.

How To: Bypass Windows Passwords Part 1

This is my first article on here, it's based off of a project that I'm working on at school which is on three ways to bypass windows user password's. If all goes as planned and you all would like I'll work on part two and part three and post them as soon as I can. I do have to give credit to Puppy Monkey Baby and The Defalt, both of whom are my classmates at college and have helped me with writing this article.

Networking Foundations: Subnetting Based on Host Requirements

Hello everyone! I hope you are having a great day so far. Today, instead of caring about networks we are going to talk about subnetting based on host requirements as promised in my first article about subnetting. Just like in the previous articles we will jump right into the examples because that's the best way to learn.

Networking Foundations: Subnetting Madness

Hello everyone! How's subnetting going? Did you practice a lot? I hope you did, but even if you didn't we will go through some more examples so you can be feeling confident after reading this article. It's all about that bad boy binary!

Decrypting [Part 1]: How to Decrypt Caeser Encrypted Texts

In this Tutorial I will show you how you can use the frequency of letters to decrypt the famous Caesar cipher. I hope it is easy to understand and helpful for getting in touch with basic cryptanalysis. If you find any mistakes or have questions feel free to ask me. Finally I ask you to give me feedback which I will take into account for the next part.

How To: Build a Directory Brute Forcing Tool in Python

While attempting to hack a web app, there may come a point where the attacker may have to escape the default directory in order to access unauthorized files. This is known as a directory traversal attack. Much as the name implies, this attack involved traversing the servers directories. But in order to move to an unauthorized directory, we need to know where those directories are. Today we'll be building a tool to brute force these directory locations based on HTTP response codes. Before we g...

How To: A Simple Udp Flooder Pt 3

in the oncoming tutorials we will post more about forging packets. I originally posted this, but because I found the techniques to be too advanced for this serie, I will post them in a new series which I will be posting in a few months. Sorry guys, but stay tuned!

Sorting (Part 3.0): Insertion Sort

Note: a bug was found in the Insertion Sort implementations. The bug was corrected in each language. Please refer to the pastebin links for the most up-to-date versions of the sample code. Any screenshots may be behind. More about the bug can be found here.

How To: Bypass Facebook's HSTS

Hey everyone, this will be a quick post. Facebook does not use HTTP Strict Transport Security (A header that tells the browser to only use HTTPS when communicating with the server) on subdomains of facebook.com. That means, if someone uses facebook in a different language, the browser will attempt to connect using HTTP first. An attacker can intercept that request and serve a different page, including a fake login one.

Networking Foundations: Exploring UDP via Wireshark(Part 2)

Hello ladies and gentlemen, welcome back to the Part 2 of our UDP & Wireshark adventure as I promised. Last time we discussed about what DNS is and how it uses UDP as its transport protocol but we left some unexplained parts behind and I'm about to investigate those with you. I would advice you to go back to Part 1 so you can have a clear understanding in case you don't feel comfortable with the topic. So our computer made its request to the DNS server and asked "Hey, I want to find out what ...

How To: Introduction to the C.H.I.P by Next Thing Co - IoT Hacking Device?

Hello NullByte, it's mkilic! This time I'm here with the C.H.I.P from NTC. Although it is not too popular, the C.H.I.P is a brand new micro computer. It is very similar to the Raspberry Pi or Beaglebone Black. The key difference with this particular board is its cost and size. The C.H.I.P only costs $9 and measures 2.5 x 1.5 inches. In addition to this, the C.H.I.P has built in 802.11 b/g/n Wifi and Bluetooth 4.0. Considering these great specs, what could a Hacker use this for? Step 1: The In...

Networking Foundations: Exploring UDP via Wireshark(Part 1)

Hello ladies and gentlemen, I'm back with another informative(hopefully) article for you all. Once again I would like to apologize for my absence for about a week or so. I have some stuff going on with my life and university and I haven't found enough time to make a fully in-depth article. In this article I'm going to walk you through one of the main networking protocols when it comes to communication across the Internet between programs, aka UDP(User Datagram Protocol).
