How to Hack Wi-Fi: Cracking WPA2 Passwords Using the New PMKID Hashcat Attack

Cracking the password for WPA2 networks has been roughly the same for many years, but a new attack requires less interaction and information than previous techniques and has the added advantage of being able to target access points with no one connected. This new attack against the PMKID uses Hashcat to crack WPA passwords and allows hackers to find networks with weak passwords more easily.

How To: Discover & Attack Raspberry Pis Using Default Credentials with Rpi-hunter

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.

How To: Scan, Fake & Attack Wi-Fi Networks with the ESP8266-Based WiFi Deauther

The price of hacking Wi-Fi has fallen dramatically, and low-cost microcontrollers are increasingly being turned into cheap yet powerful hacking tools. One of the most popular is the ESP8266, an Arduino-programmable chip on which the Wi-Fi Deauther project is based. 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: Steal Usernames & Passwords Stored in Firefox on Windows 10 Using a USB Rubber Ducky

A lot of people still trust their web browser to remember every online account password for them. If you're one of those users, you need to adopt a more secure way of managing passwords, because browser-stored passwords are hacker gold mines. With a USB Rubber Ducky and physical access to your computer, they can have a screenshot of all your credentials in their inbox in less than 60 seconds.

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: Fully Anonymize Kali with Tor, Whonix & PIA VPN

Hacking from a host machine without any form of proxying is reckless for a hacker, and in a penetration test, could lead to an important IP address becoming quickly blacklisted by the target. By routing all traffic over Tor and reducing the threat of malicious entrance and exit nodes with a VPN, we can configure Kali to become thoroughly private and anonymous.

Steganography: How to Hide Secret Data Inside an Image or Audio File in Seconds

Steganography is the art of hiding information in plain sight, and in this tutorial, I'll show you how to use Steghide — a very simple command line tool to do just that. In addition, I'll go over a bit of conceptual background to help you understand what's going on behind the scenes. This is a tool that's simple, configurable, and only takes a few seconds to hide information in many file types.

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 Hack Wi-Fi: Stealing Wi-Fi Passwords with an Evil Twin Attack

While Wi-Fi networks can be set up by smart IT people, that doesn't mean the users of the network are similarly tech-savvy. We'll demonstrate how an evil twin attack can steal Wi-Fi passwords by kicking a user off their trusted network while creating a nearly identical fake one. This forces the victim to connect to the fake network and supply the Wi-Fi password to regain internet access.

How To: Build a Beginner Hacking Kit with the Raspberry Pi 3 Model B+

If you want to follow Null Byte tutorials and try out Kali Linux, the Raspberry Pi is a perfect way to start. In 2018, the Raspberry Pi 3 Model B+ was released featuring a better CPU, Wi-Fi, Bluetooth, and Ethernet built in. Our recommended Kali Pi kit for beginners learning ethical hacking on a budget runs the "Re4son" Kali kernel and includes a compatible wireless network adapter and a USB Rubber Ducky.

Hack Like a Pro: How to Crack Online Web Form Passwords with THC-Hydra & Burp Suite

Welcome back, my hacker novitiates! In an earlier tutorial, I had introduced you to two essential tools for cracking online passwords—Tamper Data and THC-Hydra. In that guide, I promised to follow up with another tutorial on how to use THC-Hydra against web forms, so here we go. 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: Gain Complete Control of Any Android Phone with the AhMyth RAT

There are more than 2 billion Android devices active each month, any of which can be hacked with the use of a remote administration tool, more commonly known as a RAT. AhMyth, one of these powerful tools, can help outsiders monitor a device's location, see SMS messages, take camera snapshots, and even record with the microphone without the user knowing.

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: Understand & Use IPv4 to Navigate a Network

You may not know it, but the IPv4 address of your computer contains tons of useful information about whatever Wi-Fi network you're on. By knowing what your IPv4 address and subnet mask are telling you, you can easily scan the whole network range, locate the router, and discover other devices on the same network.

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.
