Hi everyone! In the previous part of this series we introduced remote code arbitrary execution via buffer overflows using all of our past experiences.
Welcome back, my tenderfoot hackers! As hackers, we often are required to get past antivirus (AV) software or other security measures. To do so effectively, we need to have some understanding of how AV software works. In this tutorial, we will take a cursory view of how AV software works so that you can better strategize on how to evade detection by it.
Welcome back, my greenhorn hackers! Continuing with my Wi-Fi hacking series, this article will focus on creating an invisible rogue access point, which is an access point that's not authorized by the information technology staff and may be a significant security vulnerability for any particular firm.
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:
Data makes the world go round. It has gotten to the point that it's considered the most valuable resource, perhaps even more important than oil. Businesses use data to collect critical information about their users and improve their services; governments utilize it to improve things like public transportation; doctors analyze data to find more ways to save lives.
Hacking web applications can sometimes be challenging due to the sheer amount of moving parts they possess. At the core of these apps are HTTP requests and parameters, but these things are often concealed from the user, due to security reasons, convenience, or both. However, a tool called Arjun can be used to discover hidden HTTP parameters in web apps.
Determining the antivirus and firewall software installed on a Windows computer is crucial to an attacker preparing to create a targeted stager or payload. With covert deep packet inspection, that information is easily identified.
One of the first steps in attacking a web application is enumerating hidden directories and files. Doing so can often yield valuable information that makes it easier to execute a precise attack, leaving less room for errors and wasted time. There are many tools available to do this, but not all of them are created equally. Gobuster, a directory scanner written in Go, is definitely worth exploring.
With a tiny computer, hackers can see every website you visit, exploit services on the network, and break into your Wi-Fi router's gateway to manipulate sensitive settings. These attacks can be performed from anywhere once the attacker's computer has been connected to the router via a network implant.
A powered-off MacBook can be compromised in less than three minutes. With just a few commands, it's possible for a hacker to extract a target's password hash and crack it without their knowledge.
If you're using a mobile device, it's a pretty safe bet that your apps are sending lots of information back and forth from their servers. To make sure there is no inappropriate data collection going on, it's worth setting up a web proxy to spy on this traffic, so you know exactly which apps are "phoning home" and when.
After a hacker has configured Metasploit on a remote private server, created a resource script for automation, and created a simple payload, he or she can begin the process of remotely controlling someone's Windows 10 computer with just a few moments of physical access — even if the computer is off.
With the addition of the OpenSSH client and server in the Windows 10 Fall Creators Update, you no longer have to rely on third-party programs to open an SSH server and connect to a Windows machine. While still a beta feature, this represents a long-overdue update fulfilling a promise made back in 2015.
Connecting to your headless Raspberry Pi on the go typically requires a network connection or carrying around bulky peripheral hardware like a screen and keyboard. With the help of an old-school connecting standard, though, you can log into your Pi from any computer using a simple cable. If you don't have a power source, you can also power your Linux distro over the cable at the same time.
The threat of an evil access point has been around for a long time, and with the rise of open public Wi-Fi, that threat is often overshadowed by how comfortable we are using third-party Wi-Fi hotspots at coffee shops and public spaces. While we've shown an evil twin attack using the Aircrack-ng suite of tools, MitmAP is a Python tool to configure custom APs for many types of wireless attacks.
After exploiting a vulnerable target, scooping up a victim's credentials is a high priority for hackers, since most people reuse passwords. Those credentials can get hackers deeper into a network or other accounts, but digging through the system by hand to find them is difficult. A missed stored password could mean missing a big opportunity. But the process can largely be automated with LaZagne.
A man-in-the-middle attack places you between your target and the internet, pretending to be a Wi-Fi network while secretly inspecting every packet that flows through the connection. The WiFi-Pumpkin is a rogue AP framework to easily create these fake networks, all while forwarding legitimate traffic to and from the unsuspecting target.
While the USB Rubber Ducky is well known by hackers as a tool for quick in-person keystroke injection attacks, one of the original uses for it was automation. In this guide, I'll be going the latter, explaining how we can use it to automate Wi-Fi handshake harvesting on the Raspberry Pi without using a screen or any other input.
Maybe you thought sitting behind a Mac gives you special protection when it comes to getting hacked. Thanks to a a new report from Check Point, you can kiss that theory goodbye. The cyber security company just uncovered the latest strain of malware — OSX/Dok — infecting all versions of macOS (previously Mac OS X).
In this tutorial I am going to show you how to create an undetectable Meterpreter Trojan using a Domain name. I have taken a few guides/tutorials and built it into one. The first part is creating the DNS Payload. The second part is creating the Executable file. Part 3 is using both in Shellter to create your undetectable Trojan. Part 4 is setting up your listener using Armitage.
Greetings fellow students! I'm currently reading a book called "Violent Python: A Cookbook for Hackers, Forensic Analysts, Penetration Testers and Security Engineers"
Hello people, I'm back for Part-3. In this part, as promised, we are going to create a client program and then we are going to test it with our server program made in Part-2.
Hello everyone! This is my first attempt at a tutorial here. There are a couple great assembly tutorials here, and I wanted to toss my coin in the fountain.
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.
If you use a wireless mouse or keyboard, you could be leaving yourself open to attacks from hackers. Researchers at Bastille had discovered in January 2016 that attackers could make use of a cheap $15 antenna to sneak into your computer through a wireless mouse or keyboard dongle (receiver).
Welcome to a tutorial on crypting technology. In this article, we will be discussing types of crypters, how they work and why they work. After defining these, we will then make our own basic crypter using the function I gave to you as a task to complete by yourself in the previous tutorial.
Welcome back, my aspiring hackers! In this series, we continue to examine digital forensics, both to develop your skills as a forensic investigator and to avoid the pitfalls of being tracked by a forensic investigator.
Welcome back Null-Byters! You finally have the pre-basics of CSS and we can begin with styling our web page. If you did not read our last adventure, I suggest you go and read it.
Welcome back, my hacker novitiates! There are many ways to hack databases, and most of these techniques require SQL injection (SQLi), which is a way of sending SQL commands back to the database from a web form or other input. In this tutorial, we will use SQL injection to get access to the underlying server. So instead of getting access to the database and its data, we will use the database as an intermediary to gain access to the underlying server.
Hello, everyone! Many of you don't even know about my existence here on Null Byte, so I thought of contributing something rather interesting. Recently, someone asked how to make your own "Bad USB," and I promised to make a how-to on this topic. In addition, it would be nice to have something related on our WonderHowTo world. So here it is!
WPA Enterprise is widely used in large corporations as it offers individual and centralized control through a server that authenticate the users (RADIUS server). In this tutorial I will show you how to break the barrier and obtain the user credentials.
Welcome back, my tenderfoot hackers! Recently, Microsoft released a new patch (September 8, 2015) to close another vulnerability in their Windows Vista, 7, 8, and 8.1 operating systems. The vulnerability in question (MS15-100) enabled an attacker to gain remote access to any of these systems using a well-crafted Media Center link (MCL) file.
Welcome back, my fledgling hackers! In this series, I am trying to develop your knowledge of digital forensics, which is valuable whether you're choosing a career in it or just want to know how your hacker activity can be traced. Few professional digital forensic investigators have a hacking background, but the best ones do.
A while back, I wrote review of my favorite hacking movies of all time. Two of my key criteria were; (1) how realistic was the hacking, and (2) are the hackers portrayed as the "good guys." This past winter, a new hacker movie was released, appropriately named Blackhat starring Chris Hemsworth (from Thor fame) as a blackhat hacker who is released from prison to stop a notorious and destructive hacker that only he can stop. Although the movie did very poorly at the box office, I thought it was...
I'm sure that many of us have heard of that nasty Shellshock vulnerability, but not very many people know how to exploit it. Try these few tricks on vulnerable websites!
As many of you know, I firmly believe that hacking is THE skill of the future. Although the term "hacking" often conjures up the image of a pimple-faced script kiddie in their mother's basement transfixed by a computer screen, the modern image of the hacker in 2015 is that of a professional in a modern, well-lit office, hacking and attempting to development exploits for national security purposes. As the world becomes more and more digitally-dependent and controlled, those that can find their...
Welcome back, my novice hackers! In this continuing series on Metasploit basics, let's next look at a module that many aspiring hackers find useful—autopwn.
Welcome back, my aspiring hackers! As I mentioned in earlier posts, the best hackers (or at least those not behind bars) have a keen understanding of digital forensics. If I am tasked to intrude upon an enemy's file server to retrieve war plans, such as in this tutorial, it is essential to my country's (and my own) well-being that it not be traced back to me. Understanding digital forensics helps us to leave without a trace and never have a trail back to us or our employer.
Probably SSH is not as clean and fast as other useful tools like netcat, but it has some features which are very useful, and when you'll need them, here's how to behave with that huge amount of computers all over your house.
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.
