How-To Guides from Null Byte: Page 14

Welcome to the final tutorial of the series on standard C. This article will cover the linked list abstract data type (ADT). There will be a lot of abstraction to try to deliver the understanding in the most basic way for easiest interpretation of what they are and how they work, then we will get into the guts of it and learn the technical code underneath. For those who have yet to grasp the concept of pointers, it's advisable that you do that first before approaching this. Having learned this...

Welcome back, my novice hackers!

In my last post I introduced how to use ncat to connect to your Pi remotely, but what's the point to if you can't actually hack? This tutorial I'm gonna show you how to use very simple tools for a much bigger purpose. With that said, boot up our Pi and lets wreck havoc.

Hello again, readers! In our previous crypter tutorial, we looked at how we could obfuscate our malware (or any program) by using a simple one-byte XOR key. In this quick tutorial, we will be looking at how a simple little tweak can create a better means of obfuscation. Let's get right into it!

While following a tutorial on python recon tools, I found a new way to access the command prompt on a school network. While there are other ways of bypassing security, it's nice to learn use Python's OS library.

Welcome back everyone! In the last training session we covered basic file input and output. We're going to leave this topic for a bit and start on something that will change the way we write scripts, classes.

Welcome back my friends !!

Welcome my aspiring hackers and programmers!

I mentioned in one of my earlier articles something about ghost hackers, and very shortly stated a thing or two of what they do.Sit back because this is a very long article

This tutorial is one technique to use the full functionality of your Pi. The small size makes it ideal for inside hacks, but still has the capabilities of a average desktop or computer. I should mention that a tutorial that OTW has done, but I'm gonna take it a step further. OTW made a brilliant article, but only touched on the surface of the possibilities. I hope this article will both show you many the possibilities and also allow you to start causing havoc, but I'm planning on making this a...

Welcome back, my tenderfoot hackers!

How's it goin'? In this tutorial, we will learn about the security issues of the popen and system functions. I've seen a few people attempting to run command line utilities or whatever it is they require with calls to these two functions but may not know the security implications which come along with it. I will show you using an example from the wargame IO Smash The Stack.

Hello fellow Nullbytiens, today we will be talking about IRC again (if you haven't read OTW's post about head over there now)and more specifically about using 1 nickname with multiple devices or IRC clients.

When performing something such as a mass mailer attack on a company, sending executables usually isn't the best option. That's why, in this tutorial, I'll be teaching you how to code a VBA script macro into a Word document in order to compromise a system. Combined with a little social engineering, this can be a very effective technique.

Hello fellow Nullbytiens, I'm Washu, a long time commenter but first time poster. Today we'll be making an IRC bot, if you haven't seen OTW's post about the new IRC channel I would encourage you to go check it out. He does a good job at explaining what IRC is and how to get set up.

Welcome back my networking geeks. In this part we are going to keep discussing about IP Addressing and I hope after you finish reading it you will become an IP wizzard.

Welcome back, my greenhorn hackers!

Welcome to a tutorial on XOR encryption. We'll be looking at what XOR is and how we can use it to encrypt or decrypt data.

Hello there Nullbytes,

Hello there! This will probably be the final tutorial on functions where we will be looking over a method called pass by reference. This technique allows us to modify large amounts of data without the overhead and return multiple values. Let's go!

Hello there Nullbyte users!

Hello fellow gray hat hackers, I wrote a program in python that helps me to fill up my proxychains.conf file, so I don't have to manually enter in the proxies. I figured I will give a little how-to of how I did it and maybe I could help some of you(hackers) out there to stay anonymous.

Five Phases of Hacking:-

Greetings aspiring hackers.

In this article I will show you how to obtain victim's credentials without cracking any hashes. There are a couple of ways to perform this task (for example dumping the SAM file and cracking the NTLM hashes), but here I will explain how to do it using PowerShell and a bit of social engineering. We are going to create a fake login popup.

First of all, Merry Christmas and Happy New Year to all Null-Byters that learn and teach in this wonderful site. In this article we will explore the basics of the meterpreter's IRB (Interactive Ruby Shell).

Welcome to my tutorial where Voidx and I will be expanding on my previous article to provide more clarity into the logic of the code.

Welcome back Java programmers!

Greetings all. Before I get into the tutorial, I would like to mention that I am fairly new to Null Byte (been lurking for some time though), and what really appeals to me about this place is its tight, family-like community where everyone is always willing to help each other and the constant search for knowledge that inhabits this subdomain is a driving motivator for me to join in. I'm glad I arrived at the right time. Anyway, wipes tears (not really)...

Before we dive into the world of frustration, I first would like to thank whoever of the admins and mods made the folder for Raspberry Pi in the How-To's, thank you. Now with that outta the way, this article is about Metasploit on Raspberry Pi (hence the title). I should say that I ran into a error, but I think I figured what the problem is. First of all this is not on Kali Linux, but on a regular Linux OS. With that said let's open up a terminal and begin.

Greetings all.

An exploit is a piece of software, a chunk of data, or a sequence of commands that takes advantage of a bug or vulnerability in order to cause unintended or unanticipated behavior to occur on computer software, hardware, or something electronic (usually computerized). Such behavior frequently includes things like gaining control of a computer system, allowing privilege escalation, or a denial-of-service attack.

First of all, I would like to apologize for a week long absents for the tutorials of this newly series, Raspberry Pi. But obviously I'm back and I present all you guys a article on turning your Raspberry Pi into a hacking platform. I'm gonna use the platform Kali Linux for the Raspberry Pi. I should note that I'm not gonna go into detail on how to install Kali Linux since OTW already has done a tutorial on how to turn your Raspberry Pi into a Hacking Pi. The point of this particular tutorial is...

I mentioned in 2015 I wanted to start a 'DoXing' series, and since I havent seen this on Null Byte, I am now going to introduce this to the community.

Hello, Null Byte! Mkilic here. I doubt anyone knows I even exist on Null Byte, so hopefully this post will allow me to become more involved in the community and also help me learn even more.

We all know them, and many of us despize them. And some might support them, regardless many have different opinions.

After seeing the title of this post from me, you might be thinking, "Why did The Joker made another post on a topic on which we already have a nice sticky post?"

What's up, peeps? In this quick tutorial, we will be looking at structs, a special kind of data type.

Hello again, and welcome back to another tutorial on functions, this time, covering recursion.

I have gotten comments from my last tutorial on not being able to do anything because of a lack of a monitor. In order to address this problem I'm gonna show you how to connect and control the Rasberry Pi through a SSH client on Linux, Mac, Windows, and Chromebook computers. This will probably we a long tutorial so please bear with me. Anyway, lets get to work.
