Welcome back, my hacker apprentices! To enter the upper echelons of hackerdom, you MUST develop scripting skills. It's all great and well to use other hacker's tools, but to get and maintain the upper hand, you must develop your own unique tools, and you can only do that by developing your scripting skills.
Before I start a series on remote exploitation, I think we should learn the basics of Perl. Perl, Ruby, C, C++, Cython and more are languages that some penetration testers just need to learn. Perl is a great language for multiple things, sadly, like many other scripting languages, it is limited by the environment in which it is designed to work in.
Welcome back, my fledgling hackers! Scripting skills are essential is ascending to the upper echelons of the hacker clique. Without scripting skills, you are dependent upon others to develop your tools. When others develop your tools, you will always be behind the curve in the battle against security admins.
In this tutorial we will be go over how we can make use of conditionals. In Perl the main conditional is the if statement. The if statement in
Today's post is a small go-to guide for beginner programmers in Null Byte. With many of our community members picking up programming from our Community Bytes, it only makes sense to lay out a one-stop guide for your reference. Hopefully this guide will help you make an educated and thoughtful choice on what programming languages you want to learn, and how you want to learn said languages.
Welcome back, my hacker novitiates! A short while ago, I introduced you to regular expressions. Regular expressions are a language that is particularly useful for finding complex text patterns in streams of data.
Welcome back my fellow hackerians, Today i'm going to tell a bit more about the famous DDOS thing. And on top of that we're going to DDOS a website.
Welcome back, my greenhorn hackers!
With the number of web applications out there today, it comes as no surprise that there are just as many vulnerabilities waiting for hackers to discover. Finding those vulnerabilities can be a difficult task, but there are plenty of tools available to make the process easier. While it won't help find any zero-days, web scanners such as Uniscan will detect common vulnerabilities.
Welcome back, my novice hackers! This next subject might seem a bit obscure, but I promise you, this lesson will benefit you significantly either as a hacker or system admin. This tutorial will cover what is usually referred to as a regular expression, or regex for short.
Many of my aspiring hackers have written to me asking the same thing. "What skills do I need to be a good hacker?"
Welcome back, my greenhorn hackers! Recently, I asked the Null Byte community what subject they would most like me to cover in future tutorials. Many of you cited scripting, and I decided it's best to cover this subject soon, so here goes.
This is my first contribution in an ongoing series on detailing the best free, open source hacking and penetration tools available. My goal is to show you some of the quality tools that IT security experts are using every day in their jobs as network security and pen-testing professionals. There are hundreds of tools out there, but I will focus and those that meet four key criteria:
Step 1: What Exploit Development Is and Why Should I Be Interested on About This Topic
Welcome back, my aspiring hackers!
Welcome back my fellow hackers! In my last few articles, I've concentrated on what is called a listener, which is basically the same thing as backdoor and rootkit, only "listener" sounds much less malevolent than the other two terms.
Penetration-testing frameworks can be incredibly useful since they often streamline certain processes and save time by having a lot of tools available in one place. Of course, the most popular pentesting framework is undoubtedly Metasploit, but there are many others out there that cater to particular needs. For auditing web applications and servers, Tishna comes in handy.
It's exciting to get that reverse shell or execute a payload, but sometimes these things don't work as expected when there are certain defenses in play. One way to get around that issue is by obfuscating the payload, and encoding it using different techniques will usually bring varying degrees of success. Graffiti can make that happen.
When attempting to compromise a target, we want as much control as possible over the victim. Metasploit's meterpreter allows us to have immense control over the victim, the only issue is that sometimes we can't land a meterpreter. We may only be able to land a standard shell, but fear not, there is a way to upgrade our shell into the all powerful meterpreter!
Welcome back, my rookie hackers! The more we know about a system or network, the better our chances of owning it and not leaving a trace for investigators to follow. One of the often overlooked sources for information is the Simple Network Management Protocol (SNMP). Many rookie hackers are not even aware of it, but it can prove to be a treasure trove of information, if you understand how it works and how to hack it.
Welcome back, my budding hackers! I've written several listener guides on creating a malicious PDF or malicious Word document that would carry in it a payload with the Meterpreter, or reverse shell enabling you to own the system. One of the hurdles to using these techniques is the antivirus (AV) software on the target system. For instance, if you try to email a malicious PDF or Word doc, it's likely that the victim system will alert the victim that it contains a virus or other malware.
With just one line of Ruby code embedded into a fake PDF, a hacker can remotely control any Mac computer from anywhere in the world. Creating the command is the easy part, but getting the target to open the code is where a hacker will need to get creative.
Using Netcat to backdoor a macOS device has its short-comings. If the compromised Mac goes to sleep, the Netcat background process will occasionally fail to terminate correctly; This leaves Netcat running infinitely in the background and the attacker with no new way into the device. As an alternative, we'll use the lesser-known Tcl shell which can handle abrupt backdoor disconnections.
What's up readers? Today I'll be introducing to you a new vulnerability called the Format String vulnerability (in case you missed the title). It won't be much, just a little motivation to keep you guys going. A little teaser, if you may.
I am very new to Null Byte but I find much of its content and community incredibly interesting. I spent quite a bit of time just chronologically going through the posts and I noticed a common theme in many of the beginner posts. Many people seem to want to know the 'secret' or a paragraph on "How to Hack" and become a hacker in a few minutes. I started off this post as a reply to a question from a beginner but thought it might be beneficial to have for those stumbling across this site.
Hello, multicolored-hat hackers!
Welcome back, my hacker novitiates! When we are trying to find vulnerabilities in a website to attack, we need a solid web server vulnerability scanner. Internet-facing web apps can open enormous opportunities for us as they are often riven with vulnerabilities and can often offer an entire point to the internal network and resources.
Welcome back, my tenderfoot hackers! I have written many tutorials on hacking using Metasploit, including leaving no evidence behind and exploring the inner architecture. Also, there are my Metasploit cheat sheets for commands and hacking scripts.
Welcome back, my aspiring hackers! In previous tutorials, I have shown you how to scan the globe for vulnerable servers and write simple scripts in BASH and Perl to perform other reconnaissance tasks. In a very recent guide, I taught how to scan vulnerable servers for Heartbleed.
Welcome back, my greenhorn hackers! I recently began a series on scripting and have received such positive feedback that I'm going to keep this series going. As I've said before, to graduate from the script kiddie to the pro hacker, you'll need to have some scripting skills. The better you are at scripting, the more advanced your hacking. Ultimately, we are leading up to developing the skills to build your own zero day exploits.
Configuring onion services for the first time can be tricky. A surprising number of system administrators make seemingly trivial mistakes that ultimately lead to catastrophic cases of de-anonymizing supposedly anonymous sites on the dark web. OnionScan is a tool designed to identify common misconfigurations in onion services and aid us in understanding how to fix them.
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.
Hello partners, first of all I would like to thank all those who have sent me positive feedback about my posts, to say that I'm always willing to learn and teach. I'm also open to answer the appropriate questions.
Many of our members here at Null Byte are aspiring hackers looking to gain skills and credentials to enter the most-valued profession of the 21st century. Hackers are being hired by IT security firms, antivirus developers, national military and espionage organizations, private detectives, and many other organizations.
Hello my anxious hackers, the week has started and here we begin a new series that I think will help many here and not only, for those that have the opportunity to follow our tutorials but they are not yet part of the community.
Welcome back, my fledgling hackers! Over the years, we have examined multiple ways to own, exploit, or compromise a system. On the other hand, we have not spent a lot of time on denial-of-service (DoS) attacks.
Welcome back, my greenhorn hackers, and happy New Year! Now that your heads have recovered from your New Year's Eve regaling, I'd like to grab your attention for just a moment to preview 2015 here at Null Byte. I hope you will add your comments as to what you would like to see, and I'll try to honor as many requests as I can.
Kali Linux is established as the go-to operating system for penetration testing, but in its default configuration, it's less than ideal for regular desktop use. While in many scenarios, a live boot or virtual environment can resolve these issues, in some situations, a full installation is better. A few simple changes can be made to a Kali Linux desktop to make it safer to use in this environment.
Hello and welcome to my article. I have made this article for anyone who wants to become a hacker, and wants to know how to get started.
