How To: Use Command Injection to Pop a Reverse Shell on a Web Server

Command injection is a technique used by hackers to execute system commands on a server, usually via a web application or some kind of GUI. This can happen when an application provides some sort of functionality to the user involving the use of system commands. When the input is not properly sanitized, commands not originally intended to be run are allowed to be executed.

Mac for Hackers: How to Organize Your Tools by Pentest Stages

With all of the bare-bones setup out of the way in our Mac for Hackers series, your Apple machine should be ready to run a significant amount of pentesting tools. We can pull tools from GitHub and compile them, we can pull dependencies or tools from Homebrew, we have both Python and Ruby. Everything is ready to go and now it's time to start building a toolbox on our local host.

How To: Use UFONet

With the release of the Mirai source code, botnets are back in a big way. In the early days of botnets, zombies (infected hosts) would report to IRC (Internet Relay Chat) channels for CNC (command and control) instructions. Modern botnets have evolved, but they continue to use the same concepts as their predecessors.

How To: Use a Misconfigured SUID Bit to Escalate Privileges & Get Root

Gaining access to a system is always exciting, but where do you go from there? Root or bust. Sure, a compromised host is a great way to run a botnet, or do some other boring, nefarious thing—but as hackers, we want root. We also want to take the easiest path possible, search out low-hanging fruit, and exploit them. SUID programs are the lowest of the low-hanging fruit.

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.

News: Magic Leap Founder Launches the Company He 'Really' Wanted to Start, a Film & Music Studio with Virtual Artists

The company augmented reality that Rony Abovitz was trying to build at Magic Leap apparently wasn't working out the way he hoped it would. That company, built on dreams, music, and future-looking entertainment, rather than truly new technology, came with a $2,300 price tag for a device using dynamics most mainstream consumers have never even tried.

News: Intel Labs Chief Reveals the Secrets to Taking Augmented Reality Mainstream

Because augmented reality is still so new to so many people, there are a number of would-be experts opining online, often repeating basic facts anyone with a spare 15 minutes can find on their own. That's why it's important to point out when someone delivers what could be considered the ultimate cheat sheet for ramping up your AR IQ if you're unfamiliar with the finer points of the space.

News: The Magic of Magic Leap's Hardware — Here's What We Know

It finally happened! In a world of "go big or go home," Magic Leap has finally done something other than tease us with vague promises and rendered video concepts. Although, other than actually showing us what the developer's kit will look like, it seems little more than a slightly different kind of a tease. To demystify this new product, we here at Next Reality decided to put together what we know about the hardware.

NR50: Next Reality's 50 People to Watch: Tony Parisi

Tony Parisi, the global head of VR/AR at Unity Technologies, has been passionately working with virtual and immersive spaces for a long time. And while the internet world we live in now is very different than when Parisi was co-authoring VRML (Virtual Reality Modeling Language) — an early attempt at creating 3D environments that would work in a web browser — some of the questions that were assumed answered are being asked again.

The Time Traveler's Companion: Surviving the Past and Future with Your Kindle

Not that long ago I wrote an article discussing what it would be like, realistically, if you were to accidentally travel back in time to the Victorian era. At the end of that article, I mentioned that the best thing you could bring with you on a time-traveling adventure is a Kindle, or similar e-reader, stuffed full of the knowledge of the 21st century. Why a Kindle? Well, I own a Kindle, and I love it. However, there's far more to it than that.

How To: Watch HBO Max on Your Roku TV Right Now

If you've jumped on board HBO Max to watch more than just HBO's content, such as DC films, Looney Tunes, Turner Classic Movies, Cartoon Network, and movies from Warner Bros., there is a downside to HBO's improved service. Namely, you cannot use it on all of your devices yet. The most notable omission is Roku players and TVs. But there are workarounds you can use until an official app comes out.
