How To: Build a DNS Packet Sniffer with Scapy and Python

In my last how-to, we built a man-in-the-middle tool. The aforementioned script only established a man-in-the-middle. Today we'll be building a tool to utilize it. We'll be building a DNS packet sniffer. In a nutshell, this listens for DNS queries from the victim and shows them to us. This allows us to track the victims activity and perform some useful recon.

How To: Create an Evil Access Point with MitmAP

The threat of an evil access point has been around for a long time, and with the rise of open public Wi-Fi, that threat is often overshadowed by how comfortable we are using third-party Wi-Fi hotspots at coffee shops and public spaces. While we've shown an evil twin attack using the Aircrack-ng suite of tools, MitmAP is a Python tool to configure custom APs for many types of wireless attacks.

How To: Crack WPS with Wifite

Hi, dear co-apprentices and wise masters. I've been recently trying to learn the basics to hacking here, and I've read all guides on Wi-Fi hacking and noticed no word is dedicated to this awesome script that comes bundled with Kali!

How To: Hide DDE-Based Attacks in MS Word

In a previous article, we learned how to take advantage of a feature, Dynamic Data Exchange (DDE), to run malicious code when a Microsoft Word document is opened. The biggest challenge of this attack is that it requires getting the user to agree to a pop-up prompt. Fortunately, since I posted that article, many new obfuscation techniques have been discovered to make this easier. Today, we explore and combine some of them to make the ultimate hidden DDE attack.

Exploit Development: How to Manipulate Code Execution with the Instruction Pointer

The one thing that separates a script kiddy from a legitimate hacker or security professional is the ability to program. Script kiddies use other people's tools, while hackers and security pros write their own tools. To that end, we're going to see how a stack overflow vulnerability allows us to flood a variable with enough input to overwrite the instruction pointer with our own commands.

How To: Use Cerberus to Take Control of Anyone's Android Phone

If you need to hack an Android device, try a remote administration tool. Known more familiarly as a RAT, there are open-source RATs that are barebones and exorbitantly priced RATs that are more polished. There are also low-cost and polished RATs that aren't intended to be RATs at all, such as Cerberus, an anti-theft solution available right on Google Play.

How To: Create a Wireless Spy Camera Using a Raspberry Pi

Surveillance is always a useful tool in a hacker's arsenal, whether deployed offensively or defensively. Watching targets yourself isn't always practical, and traditional surveillance camera systems can be costly, lacking in capabilities, or both. Today, we will use motionEyeOS running on a Raspberry Pi Zero to create a small, concealable Wi-Fi connected spy camera that is both affordable and easily concealed.

Guide: Wi-Fi Cards and Chipsets

Greetings aspiring hackers. I have observed an increasing number of questions, both here on Null-Byte and on other forums, regarding the decision of which USB wireless network adapter to pick from when performing Wi-Fi hacks. So in today's guide I will be tackling this dilemma. First I will explain the ideal requirements, then I will cover chipsets, and lastly I will talk about examples of wireless cards and my personal recommendations. Without further ado, let's cut to the chase.

News: The Hacking of Blackhat, the Movie

A while back, I wrote review of my favorite hacking movies of all time. Two of my key criteria were; (1) how realistic was the hacking, and (2) are the hackers portrayed as the "good guys." This past winter, a new hacker movie was released, appropriately named Blackhat starring Chris Hemsworth (from Thor fame) as a blackhat hacker who is released from prison to stop a notorious and destructive hacker that only he can stop. Although the movie did very poorly at the box office, I thought it was...

How To: OpenSSL Unique Encryption/Decryption Scripts

In this tutorial I will be explaining the purpose of unique encryption/decryption scripts ( I will be referring to these at "UEDS" for this tutorial). Then, I will show you how to make one. Finally I will talk about the downsides to the method I use. I will also provide links explaining the concepts and algorithms used in encryption to anyone who wants to see what is going on under the hood.

How To: Become Anonymous & Browse the Internet Safely

We all know about PRISM. The Surveillance Program allowing the U.S Government to access private user information. Such as, Google Searches, Tweets, Facebook Posts, Private Images, and other private user data. "Hiding" yourself can be very difficult, but it is possible. I'm here to show you How to Become Anonymous & Browse the Internet Safely.

Raspberry Pi: Physical Backdoor Part 1

This tutorial is one technique to use the full functionality of your Pi. The small size makes it ideal for inside hacks, but still has the capabilities of a average desktop or computer. I should mention that a tutorial that OTW has done, but I'm gonna take it a step further. OTW made a brilliant article, but only touched on the surface of the possibilities. I hope this article will both show you many the possibilities and also allow you to start causing havoc, but I'm planning on making this ...

How To: Diceware Gives You Truly Random Yet Easy-to-Memorize Passwords

Passwords are everywhere. We use them to unlock phones, computers, websites, encrypted disks, encrypted files... the list just goes on and on. Savvy users will already have a password manager of some sort that can generate a very strong password on a per site basis. However, these password managers also require a password. Not only that, it has to be something memorable.

How To: Hack Together a YouTube Playing Botnet Using Chromecasts

Imagine being able to play a video instantly on hundreds of thousands of devices across the globe. It's totally possible, as long as all of those devices have a Chromecast plugged in. When Chromecasts are left exposed to the internet, hackers can use add them to a botnet that can play YouTube videos at will. The "attack" is made even easier thanks to a simple Python program called CrashCast.

How To: Learn How Elliot from Mr. Robot Hacked into His Therapist's New Boyfriend's Email & Bank Accounts (Using Metasploit)

Social engineering is a pretty important item in a hacker's toolkit. In Mr robot there was a time, we saw Elliot using social engineering to gain access to his therapist's boyfriend's email and bank accounts by calling him and pretending to be someone from his bank, then Elliot asked him for some info that were really useful to gain access to his account, the target believed to be someone from the bank and gave him the info Elliot was looking for.

How To: Create a Reusable Burner OS with Docker, Part 2: Customizing Our Hacking Container

In the first part of my containers series, we learned how to install Docker on our local machine, pull down "hello-world" and Ubuntu containers, SSH into containers, and install software when in a container. Now, we're going to work on building, customizing, and storing our refined hacking Ubuntu container. Before we dive right in, though, let's make sure we still have a functional Docker installation.
