Format strings are a handy way for programmers to whip up a string from several variables. They are designed to save the programmer time and allow their code to look much cleaner. Unbeknownst to some programmers, format strings can also be used by an attacker to compromise their entire program. In this guide, we are going to look at just how we can use a format string to exploit a running program.
Any internet user will need to download files eventually, and most simply have faith that what they are downloading is trustworthy. This doesn't give much clarity into the contents of the file, but if the file's author published the original checksum, comparing it to the SHA-256 hash of the downloaded file can ensure nothing was tampered with.
Proxies can be quicker to use than a VPN for specific applications, like web browsers or torrent clients. Both services will hide your true IP address, but a VPN is slowed down because it encrypts all data through a VPN network, while a proxy just acts as a middleman for fetching and returning requests from a server on your behalf. When speed is needed, go proxy.
Karen Gillan must have had an absolute blast chewing the scenery as Nebula in Guardians of the Galaxy Vol. 2, seeing as how Nebula is a ball of pure, seething fury pretty much 24/7. Combine that larger-than-life personality with her iconic blue and silver cyborg look, and you have a guaranteed hit for cosplay or Halloween.
Now that we have unlocked the menu movement — which is working very smoothly — we now have to get to work on the gaze manager, but first, we have to make a course correction.
Code execution in Microsoft Word is easier than ever, thanks to recent research done by Etienne Stalmans and Saif El-Sherei. Executing code in MS Word can be complicated, in some cases requiring the use of Macros or memory corruption. Fortunately, Microsoft has a built in a feature that we can abuse to have the same effect. The best part, it does so without raising any User Account Control security warnings. Let's look at how it's done.
The new iPhone X will be released on Friday, Nov. 3, in Apple Stores located in over 55 countries and territories. For those of you who would rather skip the in-stores lines that will start building well before the 8 a.m. local time openings, you can preorder the iPhone X on Friday, Oct. 27, starting at 12:01 a.m. PDT.
The dark web is an intimidating place for a newbie hacker, but it's a powerful tool once you've learned to navigate it safely. To help you out with that, this guide will cover some need-to-know information for traversing the dark corners of the internet while keeping your identity and data safe. (Hint: Using Tor is not enough.)
Cross-compilation allows you to develop for one platform (like Kali) and compile to run on a different platform (such as Windows). For developers, it means that they can work on their platform of choice and compile their code for their target platform. For hackers, it means we can compile exploit code for Windows from Kali.
At Build 2017, the annual developer's conference, Microsoft featured a Windows Mixed Reality Academy. This class was designed to get a developer started creating Mixed Reality experiences quickly. For those of us already developing for the Microsoft HoloLens, while the class — which is now available on the Microsoft website — did offer our first real chance to work with the new Acer HMD, there was not much depth.
If you need a tiny, flexible attack platform for raining down human-interface-device (HID) attacks on unattended computers, the USB Rubber Ducky is the most popular tool for the job. By loading the Ducky with custom firmware, you can design new attacks to be effective against even air-gapped computers without internet access. Today, you'll learn to write a payload to make "involuntary backups" through copying a targeted folder to the Ducky's USB mass storage.
There are many great reasons to root your phone, but if you're not experienced with tools like ADB and Fastboot, it can seem like a daunting task. Fret not, because if you want to root your HTC 10, we're here to walk you through the process.
Apple's been hard at work adding new features and finishing touches to iOS 11, and there's evidence of it everywhere. But there's one place where these changes are more noticeable than perhaps anywhere else — Safari.
WWDC 2017 is right around the corner, where Apple is expected to reveal iOS 11, the newest version of their mobile operating system. There have been many rumors floating around about what iOS 11 will have in store for us, but not all of those features will end up in the final product — and a lot of the features you want won't actually make the cut, either. But that doesn't mean we can't hope for the best.
The Samsung Galaxy Note 8 (or Galaxy Note8, depending on how you like it) is one phone which couldn't possibly have bigger shoes to fill. Samsung's latest flagship has officially been announced, so it's time to decide whether not it's capable of filing the void left by the failed Note 7. From the revealed specifications and details, the Note 8 is turning out to be one device worth pre-ordering.
Android O has finally arrived—well, it's technically a beta version, but that isn't stopping Android enthusiasts from going crazy about it. The first Developer Preview was released earlier today and is available right now to install on Nexus and Pixel devices. While Android O doesn't have an official name or Android number yet (we're betting on "Android Oreo"), Google has released a feature list and a blog post explaining almost all of the new changes and features.
The '90s were a great decade to be alive. Before the internet became a high-availability service, we were untethered from the bombardment of media present in today's culture. Children ran through the streets with levels of physical exertion beyond what's required to capture fictional creatures found in Pokémon GO. However, there were some video game consoles that kept kids indoors, such as the Game Boy, SNES, and more importantly—the first ever PlayStation.
Humanity is standing on an infection precipice. As antibacterial resistant grows, we're running out of options, and a recent scary case of total antibiotic resistance is a frighting view of our potential future. In the end, it was septic shock that took the life of a 70-year old woman with an incurable infection. One of few such cases in the US, her death could nonetheless be the shape of things to come.
Now that we've set up Vuforia in Unity, we can work on the more exciting aspects of making physical objects come to life on the HoloLens. In this guide, we will choose an image (something that you physically have in your home), build our ImageTarget database, and then set up our Unity camera to be able to recognize the chosen image so that it can overlay the 3D holographic effect on top of it.
In the perpetual search for a renewable and convenient energy source, our bacterial friends have once again stolen the limelight.
After poor sales of last year's HTC 10 and the terrible reviews their first 2017 flagship received, HTC really needs the HTC U11 to succeed. But they're not taking things lying down, as they've come up with some interesting tech for their latest handset.
When the HoloStudy Demo app for HoloLens came out in September, it was a pretty impressive start to what could be a very valuable science tool for education. Now, Moscow-based HoloGroup, makers of HoloStudy, started an Indiegogo campaign to improve their modular teaching app.
With any continuously active software, it can start to become fairly complex after a few years of updates. New features and revisions both get layered into a thick mesh of menu systems and controls that even pro users can get bewildered by. If you are new to a certain application after it has been around for many years, it can be downright intimidating to know where to begin.
I've seen my fair share of heartbreaks when it comes to used phones. As a repair tech, I often had to try and help out customers who bought used handsets which turned out to be useless, either because it was stolen or not working on their carrier's network. More often than not, there was very little I could do. To help you from being stuck in the same situation, here are some tips to prevent you from getting scammed out of your hard earned money when buying a used handset.
As a former repair tech, I've heard the same reasons over and over as to why people opt not to purchase phone insurance. Some cite the cost—why pay extra every month for insurance when you're careful with your phone? Deductibles are expensive, so why not just spend that money on a repair instead of getting a refurbished phone as a replacement?
In my days as a hardware tech, I often came across motivated do-it-yourselfers who watched a video or two on how to repair a phone and thought that they'd give it a go. More often than not, they failed miserably and damaged their phones (and wallets) even more in the process.
Reading through various internet forums, it certainly sounds like the Google Pixel and Pixel XL are attracting more iPhone users than any of Google's previous Nexus devices. The sales figures seem to back that up, too, as the Pixel is outpacing last year's Nexus 6P, and pre-order demand has exceeded Google's expectations, causing delays in shipments. (We reached out to Google but they wouldn't give us any specifics on sales numbers or numbers of switchers.)
Harry Potter fans got a treat last week when Pottermore, a site created by Harry Potter author, J. K. Rowling, released a test that let users learn what form their Patronus protective charm would take.
When we were kids, snacks on-the-go or in our lunch box were often Kellogg's Nutri-Grain cereal bars. There were flavors like strawberry, blueberry, and our beloved apple-cinnamon.
Rice is one of those incredibly versatile pantry essentials that you can make in bulk and then freeze for later use in a quick meal during the week. It keeps well in the fridge and freezer, and there are an endless number of ways that it can be used once thawed—from rice bowls and salads to stir-fry dishes.
We've always loved a good summertime hot dog, placed lovingly in a soft simple bun with ample ketchup and mustard. But after eating hot dogs this way and this way alone for the majority of our lives, we grew tired of the same old thing.
When alcohol tastes bad, there's little you can do to save it—or so you think. While it might seem easier to toss your entire bottle of old, opened wine, or to give up and drink crappy vodka anyway, there are creative ways to turn a spoiled or just plain bad boozy beverage into one you actually want to drink.
"It just ticked me off," he said. In March 2011, Neil Singh paid $50 to back the Hanfree iPad stand on Kickstarter. The project was funded at $35,000, but production stalled, and the delivery estimates kept getting pushed back.
Yes, I understand some people may consider this a repost. However, I have been searching for this answer for 3 weeks and after reading numerous reddit post, Kali Forums post and Null byte post I finally have gotten it to work for me. I would like to compile and share this information with you guys.
When performing something such as a mass mailer attack on a company, sending executables usually isn't the best option. That's why, in this tutorial, I'll be teaching you how to code a VBA script macro into a Word document in order to compromise a system. Combined with a little social engineering, this can be a very effective technique.
INTRODUCTION Hello dear null_byters here we go again with our third part of this serie.
Welcome back, my novice hackers! One of the most common questions that Null Byte readers ask is: "How can I evade detection by antivirus software on the target?" I have already talked about how AV software works, but to obtain a deeper understanding, what better way is there than opening up and dissecting some AV software?
In 1987, two brothers, Thomas and John Kroll, began work on an image editing software, which was eventually acquired in 1988 and released to the world in 1990 by Adobe. That software was Photoshop 1.0, initially exclusive for the Macintosh platform. Over the years, Photoshop became a great wizard of image editing and gained application rockstar status.
Welcome, in this tutorial we shall we looking at creating a safe(r) way to back up your important files. The contents we will be covering are as follows;
