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.
How To: The Beginner's Guide to Defending Against Wi-Fi Hacking
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.
How To: Extract Windows Usernames, Passwords, Wi-Fi Keys & Other User Credentials with LaZagne
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.
How To: Slip a Backdoor into PHP Websites with Weevely
Backdoors are convenient to leave behind once you've already found a way into a server, and they can come in handy for a variety of reasons. They're good for developers who want a quick way into machines they're working on, or for systems administrators who want similar access. Of course, backdoors are also a hacker's best friend, and can be added in a variety of ways. One good tool for doing this is Weevely, which uses a snippet of PHP code.
How To: Upload a Shell to a Web Server and Get Root (RFI): Part 2
If you remember last time, we successfully uploaded picture with a small hidden PHP command executer embedded in it onto a server. Now, our goal is to take this a step further and get an interactive shell. To do this, we need to upload another file that either binds a port for us, or connects back. For this tutorial, we will use a Python reverse Meterpreter shell.
Hack Like a Pro: How to Build Your Own Exploits, Part 3 (Fuzzing with Spike to Find Overflows)
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.

How To: Hack 200 Online User Accounts in Less Than 2 Hours (From Sites Like Twitter, Reddit & Microsoft)
Leaked databases get passed around the internet and no one seems to notice. We've become desensitized to the data breaches that occur on a daily basis because it happens so frequently. Join me as I illustrate why reusing passwords across multiple websites is a truly awful practice — and compromise hundreds of social media accounts in the process.
How To: Perform an Attack Over WAN (Internet)
So, you want to perform an exploit on a victim, but you're not on the same network as their machine. In this tutorial, I'll be showing you how to set up a meterpreter reverse_tcp attack to work over the internet.
Hack Like a Pro: Abusing DNS for Reconnaissance
Welcome back, my tenderfoot hackers! As you know, DNS, or Domain Name System, is critical to the operation of the Internet. It provides us with the ability to type in domain names such as www.wonderhowto.com rather than the IP address. This simple service saves us from having to memorize thousands of our favorite website IP addresses. Instead, we simply type in a domain name to retrieve the website.
Hack Like a Pro: How to Conduct OS Fingerprinting with Xprobe2
Welcome back, my novice hackers! I've written a couple of articles on reconnaissance and its importance, and as I've said before, a good hacker will spend 3 to 4 more times doing reconnaissance than actually exploiting the system. If your recon isn't good, you'll likely fail, or worse—end up serving time and becoming Bubba's wife for a couple years. I can't say it enough—recon is critical.
Hack Like a Pro: How to Conduct Passive Reconnaissance of a Potential Target
Welcome back, my novice hackers! Most of my tutorials up until this point have addressed how to exploit a target assuming that we already know some basic information about their system. These include their IP address, operating system, open ports, services running, and so on.

Hack Like a Pro: How to Compile a New Hacking Tool in Kali
Welcome back, my newbie hackers! Recently, I "upgraded" to Kali as my hacking platform, despite my preference for BackTrack. I did this reluctantly, primarily because new readers here could no longer download BackTrack from their site. I want to point out here that we all must keep in mind that with any software—or for that matter, any product—that is newer is not necessarily better.
How To: Use beEF (Browser Exploitation Framework)
I'm still amazed by all the things some people just don't know. Script-kiddies often refer to Metasploit if someone asks them how to hack a computer because they think there's simply no other way. Well here I am today trying to increase your set of tools and -of course- skills.

In this article, we will enable the audio recording capability on the remote system of your roommate.
Hacking macOS: How to Connect to MacBook Backdoors from Anywhere in the World
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.
How To: Use JavaScript Injections to Locally Manipulate the Websites You Visit
JavaScript is one of the main programming languages that the Web is built on. It talks directly to your browser and exchanges information with it in ways that HTML simply cannot. With JavaScript, you are able to access browser cookies, website preferences, real-time actions, slideshows, popup dialogs and calculators, or you create entire web-based apps. The list goes on nearly forever.
How To: Hack WPA & WPA2 Wi-Fi Passwords with a Pixie-Dust Attack Using Airgeddon
Design flaws in many routers can allow hackers to steal Wi-Fi credentials, even if WPA or WPA2 encryption is used with a strong password. While this tactic used to take up to 8 hours, the newer WPS Pixie-Dust attack can crack networks in seconds. To do this, a modern wireless attack framework called Airgeddon is used to find vulnerable networks, and then Bully is used to crack them.

How To: Enumerate MySQL Databases with Metasploit
It's been said time and time again: reconnaissance is perhaps the most critical phase of an attack. It's especially important when preparing an attack against a database since one wrong move can destroy every last bit of data, which usually isn't the desired outcome. Metasploit contains a variety of modules that can be used to enumerate MySQL databases, making it easy to gather valuable information.
How To: Use Zero-Width Characters to Hide Secret Messages in Text (& Even Reveal Leaks)
You may be familiar with image-based or audio-based steganography, the art of hiding messages or code inside of pictures, but that's not the only way to conceal secret communications. With zero-width characters, we can use text-based steganography to stash hidden information inside of plain text, and we can even figure out who's leaking documents online.
How To: Crack Password-Protected ZIP Files, PDFs & More with Zydra
Everybody knows not to store sensitive information in unencrypted files, right? PDFs and ZIP files can often contain a treasure trove of information, such as network diagrams, IP addresses, and login credentials. Sometimes, even certain files that are encrypted aren't safe from attackers. That's where Zydra comes in — a tool for cracking RAR files, ZIP files, PDF files, and Linux shadow files.
How To: Obtain Valuable Data from Images Using Exif Extractors
Metadata contained in images and other files can give away a lot more information than the average user might think. By tricking a target into sending a photo containing GPS coordinates and additional information, a hacker can learn where a mark lives or works simply by extracting the Exif data hidden inside the image file.
How To: Generate Crackable Wi-Fi Handshakes with an ESP8266-Based Test Network
If you've wanted to get into Wi-Fi hacking, you might have noticed that it can be pretty challenging to find a safe and legal target to hack. But you can easily create your own test network using a single ESP8266-based microcontroller like the D1 Mini.
