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.
RouterSploit is a powerful exploit framework similar to Metasploit, working to quickly identify and exploit common vulnerabilities in routers. And guess what. It can be run on most Android devices.
The world is full of vulnerable computers. As you learn how to interact with them, it will be both tempting and necessary to test out these newfound skills on a real target. To help you get to that goal, we have a deliberately vulnerable Raspberry Pi image designed for practicing and taking your hacking skills to the next level.
One major component of Level 4 and Level 5 driverless cars is in very short supply. Venture capitalists and engineers from around the world are racing to fill the LiDAR production, price, and performance void.
It's been a while when the major web browsers first introduced HTTP Strict Transport Security, which made it more difficult to carry Man In The Middle (MITM) attacks (except IE, as always, which will support HSTS since Windows 10, surprised?).
Hello readers, and welcome to Null Byte. Before we start, for those of you who may not know me, my name is ghost_; I'm a relatively active member of our community and have been around for a while.
Many of my aspiring hackers have written to me asking the same thing. "What skills do I need to be a good hacker?"
One of the biggest problems in data security is authentication of data and its source. How can Alice be certain that the executable in her inbox is from the venerable Bob, and not from the not-so-venerable Oscar? Clearly Alice wants to know because if this file is actually sent to her by Oscar, the file might not be a game, but a trojan that can do anything on her computer such as sift through her email and passwords, upload her honeymoon pictures, or even turn on microphones and webcams. Thi...
Atari was one of the very first video game consoles, bringing the joy of arcades right into the living room. Now gaming consoles are a dime a dozen, but there's still something about those old retro systems that makes me want to travel back in time.
Video games are one of the few items that have successfully advanced and adapted over decades, while still holding its "old school" value.
If you've spent enough time in an arcade like me, you're probably well acquainted with the dreaded "ran out of quarters syndrome." Just when you're about to beat the last boss in Marvel vs. Capcom, or make it to the next level in Donkey Kong, you're all out of quarters to continue the level.
Spoofed phone calls originate from one source that's disguising its phone number as a different one, and you probably get these calls all the time. Maybe they're numbers from your local area code or for prominent businesses, but the callers are just hijacking those digits to fool you into picking up. Turns out, making a spoofed call is something anybody can do — even you.
When it comes to the ever-shifting sands of the augmented reality space, you never know which week will end up being truly historic. Well, this one was one for the history books.
It's already been a banner year for mergers and acquisitions in the augmented reality industry, with WaveOptics and Ubiquity6 among the notable companies acquired. Two of the more active M&A players, Snap and Epic Games, continued their respective buying sprees this week with major deals supporting their AR strategies.
Among the various components of the emerging augmented reality space, the most lucrative is the advertising market. The prospect of turning every object, every location, ever signpost in the real world into a discount code or virtual transaction interface is why AR will ultimately be more profitable than VR.
What does it mean when a software company obsessively focused on innovating the way we use our mobile devices to see and communicate with the world adds virtual voice agents? Possibly e-commerce magic, with a powerful layer of augmented reality.
Penetration testing, or pentesting, is the process of probing a network or system by simulating an attack, which is used to find vulnerabilities that could be exploited by a malicious actor. The main goal of a pentest is to identify security holes and weaknesses so that the organization being tested can fix any potential issues. In a professional penetration test, there are six phases you should know.
It's safe to say that we can call the annual ranking of AR investments a holiday tradition at Next Reality.
Equifax reported on Sept. 7 that it discovered a breach on July 29 which affects roughly half of Americans, many of whom don't realize they have dealings with the company. Hackers got away with social security numbers, addresses, and driver's license numbers, foreshadowing a "nuclear explosion of identity theft." Let's explore what really happened and what you and those around you can do to protect yourselves.
On April 7, 2017, residents in Dallas, Texas, woke to the sound of emergency sirens blaring all over the city. No one could shut them off, and after repeated efforts to contain the situation, the city had to shut down the entire system. While the media reported a sophisticated computer hack was responsible, the truth was much less high-tech.
What if the code you are trying to reverse engineer is obfuscated or somehow corrupted? What if no way is left? Here comes what I like to call (wrongly and ironically) the "brute force of reverse engineering".
We're still basking in the afterglow of the HUGE Snap Partner Summit last week, where Snap made Snapchat a much stronger augmented reality platform while also unveiling the AR smartglasses version of Spectacles. This week, we got a peek at how Spectacles AR started and got our hands on Lenses from Lego and Disney featured during the keynote.
The tech world was taken by surprise this week with the unexpected unveiling of Snap's augmented reality Spectacles smartglasses.
It's common knowledge these days that Apple puts great cameras into their iPhones. So, it probably comes as no surprise to learn that the iPhone 12, 12 mini, 12 Pro, and 12 Pro Max sport some excellent shooters. What you might not know, however, is that these cameras are quite literally capable of Hollywood-quality video. So don't be surprised to see one of these filming a Netflix series.
Many apps on your iPhone want to use your location, most of which are for valid reasons. But some apps can function perfectly fine without location permissions, while others have no business even requesting it. If you want to be more selective about which apps and services you give away your coordinates to, the best thing you could do is start from scratch.
If you live in the US, it's your civic duty to understand our governing bodies and the political system that puts them in place. It doesn't matter what your age is, knowing who to vote for is as important as voting at all. That starts with policing your own representatives to help decide whether or not we should re-elect them.
Who here binges TV on a regular basis? I know I do. Never before have we had so many options for watching our favorite shows, especially when you consider how easy it is to stream from anywhere on a mobile device. But sometimes, all that choice gets a little overwhelming. What services are really worth the money? Where should you be investing your Friday-night binges?
It's finally out. After months of testing, iOS 13 is available to install on your iPhone, which means over 200+ new features you can use right now. The update, released on Sept. 19, can be installed over the air or from a restore image using iTunes in macOS Mojave and older or Finder in macOS Catalina. Ditto for the 13.1 update issued on Sept. 24.
A hacker with privileged access to a Windows 10 computer can configure it to act as a web proxy, which allows the attacker to target devices and services on the network through the compromised computer. The probes and attacks appear to originate from the Windows 10 computer, making it difficult to detect the attacker's actual location.
The latest film addition in the American-produced Millennium series, The Girl in the Spider's Web, was just released on Blu-ray a few days ago. As you could expect, the movie has many hacking scenes throughout, just like the previous English and Swedish language movies centered around hacker Lisbeth Salander. Of course, with the quick pace of some scenes, the hacks can be hard to follow.
The gig economy is thriving, and if you aren't already making money with your phone, you could be missing out on easy residual income. Some people just want extra cash, and some even manage to completely ditch the 9–5, enabling them to work at their own pace and set their own hours.
There's a lot more to your iPhone's dialer screen than just entering phone numbers and hitting the green call button. It's not very obvious, but there are secret codes that you can enter on the dialer to find out information about your device, help troubleshoot issues, and mask outgoing calls, to name just a few things.
A burner number isn't just for criminals and cheating spouses. In this digital world, with many of our interactions being conducted online, a throwaway phone number acts as a buffer — it lets you enjoy the web without having to give out your personal information, such as real name or phone number.
During our last adventure into the realm of format string exploitation, we learned how we can manipulate format specifiers to rewrite a program's memory with an arbitrary value. While that's all well and good, arbitrary values are boring. We want to gain full control over the values we write, and today we are going to learn how to do just that.
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.
Coinbase is the primary go-to for many users when it comes to investing in Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Ripple (XRP), and more, due to its user-friendly interface. But before you join them, know that the ease of use comes with a price. Coinbase charges fees for each transaction, and your bank might even add charges on top of that. Plus, there is some fine print to be aware of.
First off, don't be frustrated. YOU CAN DO IT! Contrary to the message in the image above, it's NOT over. It's just beginning. And when it comes to solving the New York Times crossword puzzle, the old cliche does apply: practice makes perfect.
Still on the fence about Apple's native Notes app? The latest Notes update for iPhone, iPad, and Mac is about to change your mind. With some fantastic new features and plenty of valuable tools from previous software versions, Notes is becoming a clear winner when it comes to saving important information from your personal and professional life.
Lidar, a technology first used by meteorologists and aerospace engineers and then adopted in self-driving vehicles, has slowly crept into consumer electronics over the last five years. If you have a Pro model iPhone or iPad, there's a good chance it has a lidar sensor, and you're likely using it whether you know it or not.
Whether you're wielding an iPhone, iPad, Mac, Android phone or tablet, or even a Windows PC, this little-known secret holds the key to effortless assistance and unwavering obedience. Intrigued? I thought so.
