Null Byte Features

How To: Use Cygwin to Run Linux Apps on Windows

You'll see a lot of Linux action going down here at Null Byte. We use Linux for hacking-related stuff because it provides a more relaxed programming environment, making it easy to write exploits and tools. Linux has many features Windows is lacking, such as full control over the OS right down to the Kernel and massive availability of mature, open source (read: free & tweakable) tools & projects.

News: Anonymity, Darknets and Staying Out of Federal Custody, Part Two: Onions and Daggers

In the first part of this series, we learned about darknets, as well as how they came about. But these patches of forgotten Internet are not the oasis of free information you might think. Despite being hidden—or just harder to come across—these networks are no more safe then anywhere else on the 'clear' Internet. The nature of networking and routing means your location is always known in server logs. It only takes one phone call to your ISP with your IP address to obtain both your physical ad...

News: Anonymity, Darknets and Staying Out of Federal Custody, Part Three: Hidden Services

For a moment, picture a situation where you want to host some files or images, but you do not want it traced back to you. Perhaps you're working on a project with others and need secure data storage. Anonymity is the new shield of the 21st century—and you best protect yourself. As always here at Null Byte, we are trying to make that happen. Before someone can learn how to root a box, they need to learn how not to be found. I can not stress that point enough.

Hack Like a Pro: Metasploit for the Aspiring Hacker, Part 6 (Gaining Access to Tokens)

Welcome back, my tenderfoot hackers! Hacker newbies have an inordinate fixation on password cracking. They believe that cracking the password is the only way to gain access to the target account and its privileges. If what we really want is access to a system or other resources, sometimes we can get it without a password. Good examples of this are replay attacks and MitM attacks. Neither requires us to have passwords to have access to the user's resources.

How to Hack with Arduino: Building MacOS Payloads for Inserting a Wi-Fi Backdoor

Arduino is a language that's easy to learn and supported on many incredibly low-cost devices, two of which are the $2 Digispark and a $3 ESP8266-based board. We can program these devices in Arduino to hijack the Wi-Fi data connection of any unlocked macOS computer in seconds, and we can even have it send data from the target device to our low-cost evil access point.

Hack Like a Pro: Linux Basics for the Aspiring Hacker, Part 22 (Samba)

Welcome back, my aspiring hackers! Those of you who use Windows in a LAN environment understand that Windows machines can share directories, files, printers, etc. using "shares." This protocol dates back to the 1980s when the then dominant computer firm, IBM, developed a way for computers to communicate over the LAN by just using computer names rather than MAC or IP addresses.

News: Performance Hacks & Tweaks for Linux

If you have made the switch from Windows to Linux, I want to congratulate you in advance. I'm sure you have noticed a huge performance increase when using Linux over other operating systems. This is only half the battle, though! Most users who are new to Linux end up using Ubuntu. I have no gripes with Ubuntu, but I do not agree with their philosophy. It almost mimics Windows. Ubuntu favors ease of use, and despite valiant efforts by the development team thus far (Ubuntu is crazy fast), all o...

How To: Do an Idle Scan with Nmap

Welcome back my fellow hackers. Today I'm going to teach you how to preform an Idle Scan. You may be asking what is an Idle Scan. Its a very stealthy scan because you don't use your own ip you use a zombie (in computer terms).

Networking Foundations: Exploring UDP via Wireshark(Part 1)

Hello ladies and gentlemen, I'm back with another informative(hopefully) article for you all. Once again I would like to apologize for my absence for about a week or so. I have some stuff going on with my life and university and I haven't found enough time to make a fully in-depth article. In this article I'm going to walk you through one of the main networking protocols when it comes to communication across the Internet between programs, aka UDP(User Datagram Protocol).

News: Block Cell Phone Signals on the Carrier of Your Choice by Hacking a Radio Frequency Jammer

Cell phone jammers, a DIY endeavor for the darker crowd. I'm pretty sure we've all considered having one at some point: whether the obnoxiously loud woman next to you is announcing private bedroom stories to a crowd on the subway, or your kids are grounded from using the phone (and consequently snagged a hidden prepaid phone), sometimes having a cell phone jammer comes in handy.

I have been lurking the site for a while now reading and learning from the great minds that reside here. I, too, have some knowledge that I would like to share with all of you. This post actually comes from a personal problem I faced and had to find a solution for. Without further ado, here it is:

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: Hack WPA/WPA2-Enterprise Part 1

WPA Enterprise is widely used in large corporations as it offers individual and centralized control through a server that authenticate the users (RADIUS server). In this tutorial I will show you how to break the barrier and obtain the user credentials.

Tor vs. I2P: The Great Onion Debate

In my recent Darknet series, I attempted to connect the dots on the Deep Web. I covered the two largest anonymity networks on the Internet today, Tor and I2P. While my initial four articles were meant as an introduction, I ended up receiving a lot of interesting comments and messages asking the technical differences between the two. I'd like to thank all of you for letting me know what was on your minds, as you should always!

Hack Like a Pro: How to Hijack Software Updates to Install a Rootkit for Backdoor Access

Welcome back, my neophyte hackers! There are innumerable ways to hack a system. We must not overlook any of the possibilities if we want to "own" the system. As systems become more and more secure, we need to be vigilant in our search for weaknesses. In this hack, we'll look at abusing the trust that a user innately has for software updates to install our own listener/rootkit on their system.
