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.

News: 5 Major Problems Magic Leap One Faces on Day One

The mysterious technology product teased via an eccentric TED Talk nearly five years ago has finally been revealed, and it's called the Magic Leap One: Creator Edition. After all of the non-disclosure agreements, furtive comments from CEOs and insiders given early access to the device, and a seemingly never-ending string of hints dropped by the company's CEO, Rony Abovitz, on Twitter, we finally have a real look at the product.

How To: The Next Big Thing in Smartphone Cameras Is Machine Learning — & It's Already Here

As smartphones become more accessible, billions of people have come to depend on their features for daily life. One of the most important aspects these days is the camera. OEMs have been working for years to improve camera quality, and they seem to have finally figured it out — the best way to achieve DSLR-quality photos wasn't just with better sensors, but with better intelligence.

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: Generate Private Encryption Keys with the Diffie-Hellman Key Exchange

When we are building programs that communicate over a network, how can we keep our data private? The last thing we want is some other lousy hacker sniffing our packets, so how do we stop them? The easy answer: encryption. However, this is a very wide-ranging answer. Today we're going to look specifically at how to encrypt data in Python with dynamically generated encryption keys using what is known as the Diffie-Hellman key exchange.

News: 11 iPhone AR Demos That Will Change How We Use Our Phones

Apple demonstrated their continued interest and investment into the awesome world of augmented reality during their Sept. 12 event, highlighting a few new AR games that will appear on iPhones thanks to ARKit. But that's not all you can expect — as long as you have an iPhone with an A9 chip or later, there will be a ton of cool new AR tools, games, and other apps to play around from the App Store.

How To: Hack Forum Accounts with Password-Stealing Pictures

The pictures we upload online are something we tend to think of as self-expression, but these very images can carry code to steal our passwords and data. Profile pictures, avatars, and image galleries are used all over the internet. While all images carry digital picture data — and many also carry metadata regarding camera or photo edits — it's far less expected that an image might actually be hiding malicious code.

How To: Use a Virtual Burner Phone to Protect Your Identity & Security

Every time you make a call or send a text, you're giving the recipient your phone number. This can be quite the security vulnerability, opening yourself up to scammers, spammers, and the feds. In this how-to, we'll look at what a burner phone is, why you might want one, and how to get started using a free second phone number on your regular smartphone.

How To: Wardrive on an Android Phone to Map Vulnerable Networks

Tossing an old Android smartphone with a decent battery into your hacking kit can let you quickly map hundreds of vulnerable networks in your area just by walking or driving by them. The practice of wardriving uses a Wi-Fi network card and GPS receiver to stealthily discover and record the location and settings of any nearby routers, and your phone allows you to easily discover those with security issues.

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.

How To: Enable One-Handed Typing on Your iPhone's Stock Keyboard

Apple introduced third-party keyboards back in iOS 8, and swipe-input options like Gboard, SwiftKey, and Swype made typing on an iPhone one-handed much easier. Even better, apps like Word Flow moved the keyboard to the side of the iPhone, so there was less thumb-stretching. Well, ever since iOS 11, Apple has had its own option for better one-handed typing in the stock keyboard.

NR50: Next Reality's 50 People to Watch in Augmented & Mixed Reality

Throughout this NR50 series, we have talked about the incredible growth the augmented and mixed reality space has seen in the last year. More devices, software, developers, and use-cases seem to arrive daily. For this growth to have occurred, it took the work of many people, from many different backgrounds and skill sets — and Next Reality wants to recognize them for all that they have done and are doing.

HoloLens Dev 101: How to Create User Location Hotspots to Trigger Events with the HoloLens

One of the truly beautiful things about the HoloLens is its completely untethered, the-world-is-your-oyster freedom. This, paired with the ability to view your real surroundings while wearing the device, allows for some incredibly interesting uses. One particular use is triggering events when a user enters a specific location in a physical space. Think of it as a futuristic automatic door.

How To: Set Up a Headless Raspberry Pi Hacking Platform Running Kali Linux

The Raspberry Pi is a credit card-sized computer that can crack Wi-Fi, clone key cards, break into laptops, and even clone an existing Wi-Fi network to trick users into connecting to the Pi instead. It can jam Wi-Fi for blocks, track cell phones, listen in on police scanners, broadcast an FM radio signal, and apparently even fly a goddamn missile into a helicopter.

How To: Google Actually Has 4 Different 'Assistants'—Here's the Best One for You

The new Google Assistant is only officially available on three platforms—newer Android phones (Pixels and those running Marshmallow and Nougat), the Google Allo app, and Google Home. However, most of the Assistant's basic functionality is also bundled into the Google app for Android and iOS, which used to go by the name Google Now, but is now referred to only as Screen Search or your Google app's Feed.

Review: My 6 Months Using the 12.9-Inch iPad Pro

The 12.9-inch iPad Pro was released in stores on November 11, 2015, and a couple days later I went to an Apple Store and to check it out in person. I had mixed feelings about the tablet, but was intrigued overall—so much so that over the next few weeks, as I found myself hearing more and more about the device, a thought began to take hold in the back of my mind—I really want one. At the same time, I was hesitant about dropping roughly 10 Benjamins for a tablet!

How To: Security-Oriented C Tutorial 0x21 - Linked Lists

Welcome to the final tutorial of the series on standard C. This article will cover the linked list abstract data type (ADT). There will be a lot of abstraction to try to deliver the understanding in the most basic way for easiest interpretation of what they are and how they work, then we will get into the guts of it and learn the technical code underneath. For those who have yet to grasp the concept of pointers, it's advisable that you do that first before approaching this. Having learned thi...

Ingredients 101: The Essential Homemade Chicken Stock

The first written account of "stock" as a culinary staple goes back to 1653, when La Varenne's Cookery described boiling mushroom stems and table scraps with other ingredients (such as herbs and basic vegetables) in water to use for sauces. But really, the concept of stock has probably been around for as long as people have been using water to boil food.

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.
