In my last tutorial, I talked about creating a virus inside of a Word Document in the scenario of a mass-mailer attack. In this post, however, I'm going to be covering creating a fake image or screenshot with a meterpreter backdoor hidden inside to be used in a similar scenario. Step 1: Creating the Virus
Welcome back, my greenhorn hackers!
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.
Before I continue with a topic on strings, we first require some fundamental understanding of how memory works, i.e. what it is, how data looks in memory, etc. as this is crucial when we are analyzing vulnerabilities and exploitation. I highly suggest that your mind is clear and focused when reading the following article because it may prove to be confusing. Also, if you do not understand something, please verify all of your doubts, otherwise you may not completely understand when we touch on...

So this is my methodology for this project of writing a rootkit. Please leave feedback on what is right/wrong. I tried to simplify concepts the best I could however...
If you use Google Chrome as your default desktop/laptop browser, then Chrome OS will be pretty easy to get up and running if transitioning from Windows or macOS. Google has created an operating system that is fast, lightweight, and versatile enough to be adopted by pros and novices alike.
Hello all, this is my first submission to null byte! I noticed something a little strange, particularly that whenever Meterpreter is discussed, it is virtually always in the context of Windows. Granted, the Windows Meterpreter is more powerful than the version that can run on OS X (it has several more commands/options), but I think it is still worth noting how to do it. I've even seen some people mistakenly say that Meterpreter can only be run on Windows, which is not true. Meterpreter can ea...
When attempting to gain access to a server, there may come a point when you need to get around file upload restrictions to upload something. If we can find a way to get around the restrictions, then we can upload anything we want to the server, effectively compromising it. That is what we'll be doing here today, so let's get started!
Welcome back, my tenderfoot hackers! In this series, we are exploring the myriad of ways to hack web applications. As you know, web applications are those apps that run the websites of everything from your next door neighbor, to the all-powerful financial institutions that run the world. Each of these applications is vulnerable to attack, but not all in the same way.
Welcome back, my rookie hackers!
There are a bunch of new and interesting features packed inside of Windows 10, but one of the most exciting ones is the Microsoft Edge web browser, the long-awaited replacement of Internet Explorer.
Welcome back, my fledgling hackers! Let's continue to expand our knowledge of digital forensics, to provide you the skills necessary to be a digital forensic analyst or investigator, as well make you a better hacker overall. In your attempts to enter a system or network undetected, it is key to understand what a skilled forensic investigator can learn about you, the alleged hacker.
Welcome back, my greenhorn hackers! One of the most important issues any hacker must address is how to get past security devices and remain undetected. These can include antivirus software, intrusion detection systems, firewalls, web application firewalls, and numerous others. As nearly all of these devices employ a signature-based detection scheme where they maintain a database of known exploits and payload signatures, the key is to either:
Spotlight, Apple's selection-based search system, received a major facelift on Mac OS X Yosemite. Packed with dozens of new features, such as a central search window and increased app suggestions, the reworked Spotlight was a breath of fresh air.
Hi there again, aspiring hackers (and veterans as well)! I'm going to explain how to perform a dictionary attack on a WPA/WPA2 protected network with Wifite. Please note that this doesn't work with WPA Enterprise For that end, you'd have to use an Evil Twin to get the "Enterprise" auth attempt, and then crack it.
Welcome back, my novice hackers! Previously in my "Spy on Anyone" series, we used our hacking skills to turn a target's computer system into a bug to record conversations and found and downloaded confidential documents on someone's computer. In this tutorial, I will show you how to spy on somebody's Internet traffic.
NFC, or near-field communications, is a hardware feature that has been built into most Android phones for the last four years. It's essentially a low-power data connection that can be used to initiate a quick command by bringing your device within range of a compatible receiver, be it tap-and-pay with Google Wallet, a file transfer via Android Beam, or a Tasker profile triggered by a specific NFC tag.
This past year was a big one for WonderHowTo. Our biggest yet. In 2014 our writers, curators, and community members helped over 100 million people learn over 270 million new things. That's 40% more people than the total number of students enrolled in every single school from elementary through college across the entire United States. That's pretty awesome. I couldn't be more proud of our entire team, and of course you, the community members who've helped us grow to this point.
When the Chromecast first came out about a year ago, developers were quick to find a way to root the streaming device. Google was almost as fast, however, in updating the Chromecast's firmware to close the loophole that this method used.
Welcome back, my budding hackers. So many of you are interested in hacking Wi-Fi that I have decided to revisit my Wi-Fi Hacking series with some updated and more in-depth material. I strongly suggest that you look at some of my earlier posts, such as "Getting Started with Terms and Technologies" and "Getting Started with the Aircrack-ng Suite of Wi-Fi Hacking Tools," before continuing here. If you're ready, you can also check out our updated 2017 buying guide here.
Welcome back, my rookie hackers! Most often, the professional hacker is seeking protected information from the target system or network. This might be credit card numbers, personally identifiable information, or intellectual property (formulas, plans, blueprints, designs, etc.). Most of my Null Byte guides have been focused on getting into the system, but this only begs the question—"what do I do when I get there?"
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.
Welcome back, my greenhorn hackers!
Welcome back, my neophyte hackers! There are innumerable ways to hack a system. We must not overlook any of the possibilities if we want to "own" the system. As systems become more and more secure, we need to be vigilant in our search for weaknesses. In this hack, we'll look at abusing the trust that a user innately has for software updates to install our own listener/rootkit on their system.
For over 20 years, a tiny but mighty tool has been used by hackers for a wide range of activities. Although well known in hacking circles, Netcat is virtually unknown outside. It's so simple, powerful, and useful that many people within the IT community refer to it as the "Swiss Army knife of hacking tools." We'll look at the capabilities of Netcat and how the aspiring hacker can use it.
Ever see those cars so covered in dirt, dust, and grime that someone writes "Wash me" on it using their finger? Well, for those cars' sakes, as well as cases less extreme, a word of advice: procrastination is not a solution — it can only compound the problem. Self-cleaning cars are the stuff of the future, not the present, and your car needs attention now.
Your iPhone is fairly secure by default, but Apple's Lockdown Mode takes it to Fort Knox levels of protection. If you're a high-value target for spyware, phishing attempts, and other sophisticated cyberattacks, it's an essential feature. But for almost everyone else, it's an extreme move. If you simply want to verify someone's identity when chatting, Contact Key Verification is a more practical option.
Google Lens has easily been one of the more useful AR apps and a tantalizing tease of life with smartglasses in the not-so-distant future. Now, Apple has its own version of Lens, dubbed Live Text, built right into iOS 15 and iPadOS 15.
Apple officially announced iOS 15 at WWDC Monday, June 7. With that announcement, we got our first look at brand new features like redesigned notifications, FaceTime screen and music sharing, and Focus modes in Do Not Disturb. All of these new iPhone features are available to test out today, thanks to the iOS 15 beta.
Withstanding an attack from a motivated hacker is one of the most important responsibilities a system administrator must undertake. This is especially true for websites that may contain sensitive customer information and a high volume of users. So it's important for a sysadmin to take proactive measures to find and fix vulnerabilities in their websites.
Microsoft's built-in antimalware solution does its best to prevent common attacks. Unfortunately for Windows 10 users, evading detection requires almost no effort at all. An attacker armed with this knowledge will easily bypass security software using any number of tools.
When setting up a Raspberry Pi, it's easy to overlook changing the default password. Like many IoT devices, the Raspberry Pi's default Raspbian operating system installs with a widely-known default password, leaving the device vulnerable to remote access. Using a tool called rpi-hunter, hackers can discover, access, and drop custom payloads on any weak Pi connected to the same network.
Rooting. As an Android user, I'm sure you've heard the word once or twice. According to Kaspersky, 7.6% of all Android users root — but for the 92.4% who don't, we wanted to talk to you.
Some of the new features in iOS 15 take some getting used to, and the biggest one of those is Safari's relocated search bar, aka address bar. There are more than a few reasons why it's a jarring change, but the good news is that you can return Safari's search bar to its pre-iOS 15 position at the top of the screen.
QR codes are so handy. Nowadays, all you have to do to scan one is open your phone's camera app and tap a button. But creating one is a different story — online QR code generators aren't always trustworthy, and most phones don't have a built-in feature for it. Thankfully, Google Chrome now does.
One of the best reasons to enter Apple's ecosystem is iMessage, where you can communicate more securely with other Apple users and send and receive chats across all of your connected iPhone, iPad, iPod touch, and Mac devices. While those blue bubble conversations sync across devices, the green bubbles — SMS and MMS texts — remain on your iPhone alone unless you change a setting manually.
You're out and about, and nothing on your iPhone will load. A glance at the settings shows a saved Wi-Fi network with full bars that your iPhone had connected to automatically, but you're not getting any internet. If you've experienced this, you're not alone, and there's something you can do about it. You'll even increase privacy and security on your iPhone in the process.
If you want to control electronic devices, such as a relay or motor, you can do so using MicroPython with an ESP8266 and web browser. Usually, you'd program an ESP8266 using Arduino, but C++, which Arduino uses, is not always the easiest programming language for beginners to learn.
