Welcome back, my fledgling hackers! One of the first issues any hacker has to address is reconnaissance. Before we even begin to hack, we need to know quite a bit about the target systems. We should know their IP address, what ports are open, what services are running, and what operating system the target is using. Only after gathering this information can we begin to plan our attack. Most hackers spend far more time doing reconnaissance than exploiting.
When it comes to attacking devices on a network, you can't hit what you can't see. Nmap gives you the ability to explore any devices connected to a network, finding information like the operating system a device is running and which applications are listening on open ports. This information lets a hacker design an attack that perfectly suits the target environment.
Computers all over the world rely on a program called "libssh" to use the SSH communications protocol, which allows trusted users to log in and administer computers remotely. Due to a flaw in libssh, fooling a computer into granting SSH access is as easy as telling it you already have permission. The vulnerability can lead to an attacker gaining complete control over a device.
There are two types of bad USBs out there. One lets you trick the computer into thinking it's a keyboard or other USB device, and the other goes straight over malicious into computer killing territory.
Alright, this will be my first tutorial in C. Note that this guide is written for Linux.
Today I will show you how to make a metasploit exploit really quickly. This tutorial is mainly applied to stack based buffer overflows and seh buffer overflows exploits .There is a simple way for rop exploits too but I will dedicate a special tutorial on this subject.
Recently, I've been learning Ruby as a second scripting language. But one topic I never covered with the many lessons online were sockets. So I did some research and came up with a very simple client/server connection that sends a string over the socket.
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.
With more people joining the internet scene each day it's important that it's security is.. well it has to be good. Of course everything can be hacked and that's the way hackers work. They know there IS a vulnerability but they don't don't know the rest. in this article i'll try to explain the big difference between HTTP and HTTPS
UnrealIRCd is an open-source IRC server that has been around since 1999 and is perhaps the most widely used one today. Version 3.2.8.1 was vulnerable to remote code execution due to a backdoor in the software. Today, we will be exploiting the vulnerability with Metasploit, examining the underlying code to understand it, and creating our own version of the exploit in Python.
While SSH is a powerful tool for controlling a computer remotely, not all applications can be run over the command line. Some apps (like Firefox) and hacking tools (like Airgeddon) require opening multiple X windows to function, which can be accomplished by taking advantage of built-in graphical X forwarding for SSH.
The $35 Raspberry Pi is an amazingly useful single-board computer (SBC) with a good balance of price, performance, and connectivity options. But for some projects, it just isn't enough. Whether you need more computing power, a smaller size, or better machine-learning capabilities, there are other options available.
The road to becoming a skilled white hat is paved with many milestones, one of those being learning how to perform a simple Nmap scan. A little further down that road lies more advanced scanning, along with utilizing a powerful feature of Nmap called the Nmap Scripting Engine. Even further down the road is learning how to modify and write scripts for NSE, which is what we'll be doing today.
Transferring hundreds of screenshots, webcam recordings, keystroke logs, and audio recordings between your VPS and a local Kali machine can be tricky. Services like Dropbox don't always have the best privacy policies and suffer data breaches just like any other website. To mitigate these risks, we'll use a secure, open source, and decentralized alternative.
Hello, I'm a new guy around here and since I'm not seeing much tutorials in C i thought of contributing with something relatively simple. This will be a short series.
Do you remember my last article on how to hook any web browser with MITMf and BeEF? Well, we are using the tool once again, but this time for auto-backdooring....
Hi all, Pro Hackers/Crackers, Let's see how we can use batch for our own Protection instead of exploiting someone with it.
NOTICE: Ciuffy will be answering questions related to my articles on my behalf as I am very busy. Hope You Have Fun !!!
Welcome back, my budding hackers! One of the most time-consuming, but necessary, activities in hacking is reconnaissance. Before we can hack a system, we need to know what operating system it's running, what ports are open, what services are running, and hopefully, what applications are installed and running.
Welcome back, my nascent Hackers! In my last blog, we looked at a passive way to gather information necessary for a hack. The advantage of using passive recon is that it's totally undetectable, meaning that the target never knows you're scouting them and you leave no tracks. The disadvantage, of course, is that it's limited to only some websites and not entirely reliable.
The conversation of which operating system is most secure, macOS vs. Windows, is an ongoing debate. Most will say macOS is more secure, but I'd like to weigh in by showing how to backdoor a MacBook in less than two minutes and maintain a persistent shell using tools already built into macOS.
If you want to carry a variety of network adapters without looking suspicious, a perfect solution is accessing them through Airserv-ng. Tucked away in the Aircrack-ng suite, this tool allows a hacker to plug any number of network adapters into a Raspberry Pi and access them over a Wi-Fi or Ethernet connection.
Automating port scanners, directory crawlers, and reconnaissance tools can be complicated for beginners just getting started with Kali Linux. Sparta solves this problem with an easy-to-use graphical interface designed to simplify a penetration tester's tasks.
A hacker with privileged access to a Windows 10 computer can configure it to act as a web proxy, which allows the attacker to target devices and services on the network through the compromised computer. The probes and attacks appear to originate from the Windows 10 computer, making it difficult to detect the attacker's actual location.
Things that are supposed to make life easier for developers and users are often easy targets for exploitation by hackers. Like many situations in the tech world, there is usually a trade-off between convenience and security. One such trade-off is found in a system known as Distributed Ruby, which can be compromised easily with Metasploit.
Hacking Wi-Fi is a lot easier than most people think, but the ways of doing so are clustered around a few common techniques most hackers use. With a few simple actions, the average user can go a long way toward defending against the five most common methods of Wi-Fi hacking, which include password cracking, social engineering, WPS attacks, remote access, and rogue access points.
Backdooring a powered-off MacBook is easy when a few minutes of physical access is allowed. That attack works well if the hacker also shares a Wi-Fi network with the victim, but this time, I'll show how to remotely establish a connection to the backdoored MacBook as it moves between different Wi-Fi networks.
Command injection is a technique used by hackers to execute system commands on a server, usually via a web application or some kind of GUI. This can happen when an application provides some sort of functionality to the user involving the use of system commands. When the input is not properly sanitized, commands not originally intended to be run are allowed to be executed.
Single sign-on (SSO) lets users login across different sites without having to manage multiple accounts. I'm sure most of us appreciate the convenience of seeing "Sign in with …" buttons that let us login with a single username. Hackers, however, see a possible avenue for exploitation, and you'll soon learn how an attacker can exploit a SAML vulnerability to assume another user's identity.
The public leaks of NSA tools and information have led to the release of previously secret zero-day exploits such as EternalBlue, which was used in the notorious WannaCry ransomware attack. Despite multiple patches being released, many users have failed to update their systems, so many devices are still vulnerable to these now-public attacks.
Welcome back everyone! It's been awhile hasn't it? Sorry for being so quiet, but my CCNA courses have really picked up recently. In the last article we covered how to import modules and how we can use them. In this article, we'll actually be covering a module that is essential to the hacking aspect of Python, sockets.
Hello aspiring hackers, It's been a while since I wrote a tutorial, so I figured I might just share one of the tools that I have created to help the community grow.
OK, In my last Tutorial we made a Server for sending Instructions to a Client. This time we will build the Client. Fire up your favourite Python environment and get the Code here.
Welcome back, my hacker novitiates! In the previous two posts in this series, we looked at the basics of buffer overflows. In this post, we will look at one technique for finding buffer overflows. We will try to send random, oversized, and invalid data at a variable to see whether we can make it crash or overflow. This process is known as fuzzing. It is often the first step to developing an exploit, as we need to find some variable that is susceptible to overflowing.
Social Engineering was mentioned a few times here on Null Byte, but not very many explained what it is, or how to do it. I love this quote because it's true: Social Engineering is the key to carrying out client side attacks, and all you need is a little creativity!

It seems like every day now that we see a new headline on a cyber security breach. These headlines usually involve millions of records being stolen from some large financial institution or retailer. What doesn't reach the headlines are the many individual breaches that happen millions of times a day, all over the world.
Welcome to this short and easy tutorial on hacking and DDosing (is that even a word I don't know) anyways lets get started
Welcome back, my novice hackers! My recent tutorials have been focused upon ways to NOT get caught. Some people call this anti-forensics—the ability to not leave evidence that can be tracked to you or your hack by the system administrator or law enforcement.
Brute-forcing is an easy way of discovering weak login credentials and is often one of the first steps when a hacker finds network services running on a network they gain access to. For beginners and experienced hackers alike, it's useful to have access to the right tools to discover, classify, and then launch customized brute-force attacks against a target. BruteDum does it all from a single framework.
