How to Hack Wi-Fi: Capturing WPA Passwords by Targeting Users with a Fluxion Attack

With tools such as Reaver becoming less and less viable options for penetration testers as ISPs replace vulnerable routers, there becomes fewer certainties about which tools will work against a particular target. If you don't have time to crack the WPA password, or it is unusually strong, it can be hard to figure out your next step. Luckily, nearly all systems have one common vulnerability you can count on—users!

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 Wi-Fi: Disabling Security Cameras on Any Wireless Network with Aireplay-Ng

Electronic warfare tactics work by jamming, disrupting, or disabling the technology a target uses to perform a critical function, and IoT devices are especially vulnerable to attacks. Wireless security cameras like the Nest Cam are frequently used to secure critical locations, but a hacker can surgically disable a webcam or other Wi-Fi connected device without disturbing the rest of the network.

Hack Like a Pro: How to Clone Any Website Using HTTrack

Welcome back, my hacker novitiates! Recently, I demonstrated a hack where you could redirect traffic intended for one site, such as, to your fake website. Of course, to really make this work, you would need to make a replica of the site you were spoofing, or better yet, you could simply simply make a copy of the original site and host it on your own server!

How To: Seize Control of a Router with RouterSploit

A router is the core of anyone's internet experience, but most people don't spend much time setting up this critical piece of hardware. Old firmware, default passwords, and other configuration issues continue to haunt many organizations. Exploiting the poor, neglected computer inside these routers has become so popular and easy that automated tools have been created to make the process a breeze.

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.

How To: Hack Coin-Operated Laudromat Machines for Free Wash & Dry Cycles

Most people have had the unfortunate experience of not having a washer and dryer at some point. Apartments in my area tend to charge at least one hundred dollars extra for the units with washer and dryer hookups, and even more if you want a unit with an actual washer and dryer installed already. If you are young and just starting out, this may be hard for you to manage with your current salary. If you have no washer and dryer, the only alternative is the laundromat.

How To: Create a Bump Key to Open Any Door

Lockpicking is a skill that takes years upon years to master. Locks come in all sorts of shapes and sizes, but have common ground in how they work. Most cylinder locks have "tumblers," which are metallic cylindrical objects that sit vertically to the actual locking mechanism. Tumblers have five or six holes with rounded key pins of various height in them, each needing to meet an exact height or the cylinder in the center (the lock itself) will not be allowed to turn. This is the reason why yo...

Hack Like a Pro: How to Use Netcat, the Swiss Army Knife of Hacking Tools

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.

How to Hack Wi-Fi: Creating an Evil Twin Wireless Access Point to Eavesdrop on Data

Welcome back, my greenhorn hackers! Now that we're familiar with the technologies, terminology, and the aircrack-ng suite, we can finally start hacking Wi-Fi. Our first task will be to creating an evil twin access point. Many new hackers are anxious to crack Wi-Fi passwords to gain some free bandwidth (don't worry, we'll get to that), but there are so many other Wi-Fi hacks that are far more powerful and put so much more at risk than a bit of bandwidth.

How To: Leverage a Directory Traversal Vulnerability into Code Execution

Directory traversal, or path traversal, is an HTTP attack which allows attackers to access restricted directories by using the ../ characters to backtrack into files or directories outside the root folder. If a web app is vulnerable to this, an attacker can potentially access restricted files that contain info about all registered users on the system, their permissions, and encrypted passwords.

How To: Make Your Own Bad USB

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!

Video: How to Crack Weak Wi-Fi Passwords in Seconds with Airgeddon on Parrot OS

A weak password is one that is short, common, or easy to guess. Equally bad are secure but reused passwords that have been lost by negligent third-party companies like Equifax and Yahoo. Today, we will use Airgeddon, a wireless auditing framework, to show how anyone can crack bad passwords for WPA and WPA2 wireless networks in minutes or seconds with only a computer and network adapter.

How To: Dox Anyone

Doxing is the act of finding one's personal information through research and discovery, with little to no information to start with. You may have seen doxing in the news, for instance when not so long ago, hacker team Anonymous doxed and reported thousands of twitter accounts related to ISIS. Doxing can be useful for finding the address of a coworker, or simply investigating people on the internet. The tutorial I will provide to you now will teach you the basics of doxing and how you can prot...

How to Hack Wi-Fi: Automating Wi-Fi Hacking with Besside-ng

In this how-to, I will be demonstrating a few of the tactical applications of Besside-ng, the hidden gem of the Aircrack-ng suite of Wi-Fi hacking tools. When run with a wireless network adapter capable of packet injection, Besside-ng can harvest WPA handshakes from any network with an active user — and crack WEP passwords outright. Unlike many tools, it requires no special dependencies and can be run via SSH, making it easy to deploy remotely.
