Eggs are a staple food for most Americans, which is no surprise, considering how necessary they are in savory and sweet recipes alike. On their own, they're usually not too eggs-citing. However, these clever egg hacks will make your egg-making easier, more fun, and more intere ...more

Nmap is more powerful than you know. With a few scripts, we can extend its functionality beyond a simple port scanner and start to identify details about target servers sysadmins don't want us to know. Possibly the most popular and well-known reconnaissance tool currently ava ...more

Who am I? First let me introduce myself. I am Th3skYf0x, an -well lets call it experienced- hacker and i recently found this site and right after that i found this Null Byte "world" soo i thought... Why not teaching instead of doing nothing with my knowledge. Let me get one ...more

Leaked databases get passed around the internet and no one seems to notice. We've become desensitized to the data breaches that occur on a daily basis because it happens so frequently. Join me as I illustrate why reusing passwords across multiple websites is a truly awful prac ...more

Welcome back, my aspiring hackers! One of the areas that often gives Linux newcomers problems are the environment variables. Although Windows systems have environment variables, most users, and for that matter, most administrators, never manage their environment variables. To ...more

General Electric isn't known for their Christmas lights, but maybe they should be, because their GE Color Effects are pretty awesome. Especially the LED Color Effects G-35 String sets. And especially when someone named Darco hacks them. Darco, whose real name is Robert Sun Qu ...more

The USB Rubber Ducky is a well-known hacking device in the cybersecurity industry, but it needs to be preprogrammed before it can be used. That means it's not easy to issue commands to a target computer since you can't interact with it from afar after plugging it in. And if yo ...more

The build.prop file in an Android device is home to many system-level values and settings. Everything from screen density to video recording quality is covered in this file, and people have been editing these entries to get new functionality and better performance since Androi ...more

Welcome back, my nascent hackers! We have spent a lot of time in previous tutorials focused on hacking the ubiquitous Windows systems, but the vast majority of "heavy iron" around the world are Linux or Unix systems. Linux and Unix dominate the world of Internet web servers w ...more

Welcome back, my tenderfoot hackers! Now that we have begun this trip down web app hacking lane, we need to first address target reconnaissance. Like any hack, reconnaissance is critical. (Are you tired of me saying that yet?) There is no better telltale sign of a script-kid ...more

Pop-Tarts are a pretty iconic breakfast food. And while I'm more of a bacon, eggs, and toast person myself... sometimes a sweet, gooey, artificially-flavored treat is just what you need in the morning. Yet, despite the fact that I do enjoy Pop-Tarts, I've always found them a l ...more

Welcome back, my amateur hackers! As many of you know, Null Byte will soon be re-establishing its IRC channel. In preparation of that event, I want to show how to set up a secure IRC client with OTR, or Off the Record. OTR does all the right things to make your instant messa ...more

Welcome back, my nascent hackers! One of the many reasons I write this blog is to help you keep the Internet free and open. Throughout human history, whenever a government or other powerful entity has wanted to subjugate a people or group, the first thing they do is isolate t ...more

Welcome back, my greenhorn hackers! Earlier in this series, I showed a you a couple of different ways of fingerprinting webservers. Probably the easiest way, is to use netcat and connect to port 80 and pull the webserver banner. The banner is simply the application advertisi ...more

It's possible to stream a MacBook's entire computer screen without using Apple's Screen Sharing application and without opening any ports on the target device. A hacker with low user privileges on the backdoored Mac may be able to view a victim's every move in real time no mat ...more

If you thought humans were reading your résumé, think again. Robots do, and their one solitary objective is to systematically crush the hopes and dreams of those who don't make the cut. Instead of paying a few humans to read thousands of résumés over a couple weeks, many compa ...more

Welcome back, hacker novitiates! In the next few hacks, we will be breaking into Windows servers. In this installment, we will learn to add ourselves as a user to a Windows 2003 server. Of course, when we have added ourselves as a user, we can come back any time and simply log ...more

This tutorial is for people who want to try different types of hacks in an environment that is the same for everyone so it will help people to ask questions and learn. This series assumes you know how to run a VM and network them together. This series also assumes that the ser ...more

Welcome back, my hacker novitiates! In the previous two posts in this series, we looked at the basics of buffer overflows. In this post, we will look at one technique for finding buffer overflows. We will try to send random, oversized, and invalid data at a variable to see wh ...more

Welcome back my fellow army of hackers! Today we'll be hacking a website. Hacking is technically not the right word used here. It should be defacing! So we are going to deface a website... What's Defacing? Website defacement is an attack on a website that changes the visual ...more

Welcome back, my hacker novitiates! Finding vulnerabilities in systems can be one of the most time-consuming tasks for a hacker. There will be times, though, when you'll find yourself in a position that you know that a particular port represents a vulnerable application or se ...more

The cell phone has come a long way. The very first "mobile devices" were made and used by the military in the late 1930s, with the first commercial mobile telephone service introduced by Bell in 1946. These devices were hardly what we'd call mobile today—some took up the whole ...more

Social Engineering was mentioned a few times here on Null Byte, but not very many explained what it is, or how to do it. I love this quote because it's true: Social Engineering is the key to carrying out client side attacks, and all you need is a little creativity! Social Eng ...more

It's a common misconception that iPhones are impervious to cyberattacks and "more secure" than Android. And when an iPhone does get hacked, it's nearly impossible to tell that it happened. Vulnerabilities in iOS are common, and Apple tries to tackle them with each security up ...more

Welcome back, my hacker novitiates! In the previous part of this series, we looked at how to use Metasploit's web delivery exploit to create a script to connect to a UNIX, Linux, or OS X machine using Python. Many members of the Null Byte community have asked me, "Can we do t ...more

Encrypting payloads and encoding stagers are more effective against macOS than one might think. It's very easy to evade VirusTotal and macOS antivirus software using a few simple tricks. The goal of this project was to locate a known and easily detectable macOS payload, then ...more

Just like Leslie Knope, I love waffles. Unlike that imaginary character, I don't require that my waffles come from JJ's Diner. I have a deep affinity for frozen waffles as well as the homemade ones. They're so convenient! A few moments in the toaster, and you have a great foun ...more

Using just a small sticky note, we can trigger a chain of events that ultimately results in complete access to someone's entire digital and personal life. Imagine arriving home one night after work and there's a Post-it note on your apartment door with the website "your-name- ...more

Last Friday's mission was to accomplish solving HackThisSite, realistic 3. The third mission in a series of realistic simulation missions was designed to be exactly like situations you may encounter in the real world, requesting we help a friend restore a defaced website about ...more

Complex shell scripts can be implanted into photo metadata and later used to exploit a MacBook. In addition to obfuscating the true nature of an attack, this technique can be used to evade network firewalls as well as vigilant sysadmins. In this attack scenario, a malicious c ...more
