Although you can use Tamper Data for this purpose, I want to introduce you to another tool that is built into Kali, Burp Suite.

How To: The Hacks Behind Cracking, Part 1: How to Bypass Software Registration

If you've ever wondered how software pirates can take software and crack it time and time again, even with security in place, this small series is for you. Even with today's most advanced methods of defeating piracy in place, it is still relatively easy to crack almost any program in the world. This is mainly due to computer processes' ability to be completely manipulated by an assembly debugger. Using this, you can completely bypass the registration process by making it skip the application'...

How To: Run Kali Linux as a Windows Subsystem

Kali Linux is known as being the de facto penetration-testing Linux distribution but can be a pain to use as an everyday OS — even more of a pain if that means carrying around a second laptop or the constant frustration of using the finicky Wi-Fi on virtual machines. But there's another option: installing a Kali subsystem on your Windows computer as a convenient compromise.

On this inexpensive board, a hacker can create fake networks, clone real ones, or disable all Wi-Fi in an area from a slick web interface.

How To: Hide a Virus Inside of a Fake Picture

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

How To: Brute-Force Nearly Any Website Login with Hatch

The tactic of brute-forcing a login, i.e., trying many passwords very quickly until the correct one is discovered, can be easy for services like SSH or Telnet. For something like a website login page, we must identify different elements of the page first. Thanks to a Python tool for brute-forcing websites called Hatch, this process has been simplified to the point that even a beginner can try it.

How To: Write an XSS Cookie Stealer in JavaScript to Steal Passwords

JavaScript is one of the most common languages used on the web. It can automate and animate website components, manage website content, and carry out many other useful functions from within a webpage.

How To: Use Mitaka to Perform In-Browser OSINT to Identify Malware, Sketchy Sites, Shady Emails & More

Web browser extensions are one of the simplest ways to get starting using open-source intelligence tools because they're cross-platform. So anyone using Chrome on Linux, macOS, and Windows can use them all the same. The same goes for Firefox. One desktop browser add-on, in particular, makes OSINT as easy as right-clicking to search for hashes, email addresses, and URLs.

How To: Set Up a Headless Raspberry Pi Hacking Platform Running Kali Linux

The Raspberry Pi is a credit card-sized computer that can crack Wi-Fi, clone key cards, break into laptops, and even clone an existing Wi-Fi network to trick users into connecting to the Pi instead. It can jam Wi-Fi for blocks, track cell phones, listen in on police scanners, broadcast an FM radio signal, and apparently even fly a goddamn missile into a helicopter.

How To: Dox Anyone

The tutorial I will provide to you now will teach you the basics of doxing and how you can prot...

How To: Use the Chrome Browser Secure Shell App to SSH into Remote Devices

Many guides on Null Byte require using the Secure Shell (SSH) to connect to a remote server. Unfortunately for beginners, learning to use SSH can become a confusing mix of third-party programs and native OS support. For Chrome OS users, using SSH is even more difficult. We'll fix this by using the Chrome Secure Shell to establish an SSH connection from any device that can run a Chrome browser.

How To: Crack Shadow Hashes After Getting Root on a Linux System

After gaining access to a root account, the next order of business is using that power to do something more significant. If the user passwords on the system can be obtained and cracked, an attacker can use them to pivot to other machines if the login is the same across systems. There are two tried-and-true password cracking tools that can accomplish this: John the Ripper and Hashcat.

How To: Hunt Down Social Media Accounts by Usernames with Sherlock

With Sherlock, we can instantly hunt down social media accounts created with a unique screen name on many online platforms simultaneously.

How To: Find Anyone's Private Phone Number Using Facebook

Facebook really wants your phone number, nagging you for one as soon as you join. This isn't all bad since it can help secure your account with two-factor authentication. On the flipside, this makes it easy to reveal the private phone numbers of virtually anyone on Facebook, including celebrities and politicians. We're going to look at how a hacker would do this and how to protect yourself.

How To: Use Ettercap to Intercept Passwords with ARP Spoofing

ARP spoofing is an attack against an Ethernet or Wi-Fi network to get between the router and the target user. In an ARP-spoofing attack, messages meant for the target are sent to the attacker instead, allowing the attacker to spy on, deny service to, or man-in-the-middle a target. One of the most popular tools for performing this attack is Ettercap, which comes preinstalled on Kali Linux.
