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.
Being able to write your own hacking tools is what separates the script kiddies from the legendary hackers. While this can take many forms, one of the most coveted skills in hacking is the ability to dig through the binary files of a program and identify vulnerabilities at the lowest level. This is referred to as binary exploitation, and today we're going to check out a tool known as Protostar.
Samsung has finally rolled out the Android Oreo update for the Galaxy S8 and S8+. If you're just now getting the update, you'll be happy to know that your Galaxy just got upgraded with plenty of cool new features. Like previous updates, Samsung has improved upon its software by including a new look and new functionality.
Surveillance is always a useful tool in a hacker's arsenal, whether deployed offensively or defensively. Watching targets yourself isn't always practical, and traditional surveillance camera systems can be costly, lacking in capabilities, or both. Today, we will use motionEyeOS running on a Raspberry Pi Zero to create a small, concealable Wi-Fi connected spy camera that is both affordable and easily concealed.
Virtual private networks, or VPNs, are popular for helping you stay anonymous online by changing your IP address, encrypting traffic, and hiding your location. However, common IoT devices, media players, and smart TVs are hard to connect to a VPN, but we have a solution: Turn a Raspberry Pi into a router running through PIA VPN, which will ensure every connected device gets the VPN treatment.
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.
When WhatsApp first came out in 2010, it quickly gained notoriety as a great way to meet new people all over the world thanks to group chats, which allow multiple admins for each group that can all add participants from their own contacts lists.
Greetings all. Today I intend to append a new series to my mini-collection of posts. This series will consist of informative guides for the purpose of depicting certain aspects of the White Hat profession that I believe are of profound importance. Furthermore, I will keep this series simple for everyone to follow, regardless of your tech level. So without further ado, let's get right into it.
Have you ever used an open wifi, which after you connect displays a website to enter your credentials to get internet? That website is called captive portal and widely used in airports, hotels, universities etc. Have you ever wondered what would happen if someone would set up an open wifi with the same name displaying a very similar web page asking for credentials? Usually if there are multiple wifi networks with the same name and encryption, devices only display the one with the highest sign...
Making a good pie crust can seem intimidating to the uninitiated, but once you master this skill, a whole world opens up to you. Not only can you make all manner of fruit, custard, and cream-filled pies once you know all the tricks, you can branch out into the world of quiches, savory pies, and flaky, crispy turnovers, too. We've already told you how to get perfect, firm fruit pie fillings, so now, let's learn about crust.
The launch of Android 4.1 Jelly Bean was also the launch of Google Now, a service that was supposed to one-up Siri, the resident personal assistant for iOS devices. Google Now offered enticing features, but its launch went unnoticed by a great many Android users.
Despite the security concerns that have plagued Facebook for years, most people are sticking around and new members keep on joining. This has led Facebook to break records numbers with over 1.94 billion monthly active users, as of March 2017 — and around 1.28 billion daily active users.
I don't know how many of you had this experience in your youth, but when I was a kid, I used to actively think about what would happen if I suddenly woke up in a fantasy land, or were to pass through a portal into another space and time. I knew it wouldn't really happen, but when you're a kid, these can be important issues to you. So I slept with my glasses on every night, just in case. Photo from George Pal's The Time Machine.
One of the hardest, most intimidating parts of making your own Steampunk guns from scratch is the wooden stock of the gun. To be fair, it's probably the hardest part. It requires the most artistry, and is the easiest to mess up.
In the first part of this two-part guide, I covered cutting, grooving, beveling, making holes, and stamping/tooling. I hope you enjoyed that part, because we're pushing the accelerator to the floor and moving ahead at full speed!
Notch loves Halloween. He must, because he keeps putting scarier and scarier things into Minecraft around Halloween time!
Visit a webpage on your iPhone, iPad, or Mac, and there's a good chance you'll be bombarded with distractions such as ads, fullscreen pop-ups, cookie consents, log-in requests, notifications, email signups, sticky videos, and calls to action. If you're using Safari and content blockers, "Block Pop-ups," and Reader mode can't hide the elements you need, Apple's got a new tool you should be excited about.
Some websites require you to perform a verification task so they know you're human and not a bot. It helps websites curb spam, abuse, unauthorized access, and cyberattacks but also adds an obstacle for anyone trying to visit their content. If you find it more of a nuisance than a necessary evil, there's an easy way to reduce the number of human verification prompts you receive on your iPhone, iPad, and/or Mac.
With iOS 17, Apple News integrates more deeply with Apple Podcasts and Apple Stocks and has become a bit more fun thanks to new crossword puzzles. But that's not all that appears in the updated News app.
Of all the new features and changes on iOS 16.5, the Apple News app has the most, and there are a few big ones that will change the way you read stories. Some updates even affect Apple News on iPadOS 16.5; the most significant ones apply to both free users and Apple News+ subscribers.
Gaming just got easier, thanks to Apple. A secret feature on your iPhone or iPad makes it so much easier to beat that level or opponent you can't seem to defeat, and it can even help you learn to play a new game faster.
Is the emoji you're using really the one you think it is? While you can use any emoji that looks like it fits what you have to say, it may have been created for a different purpose. On an iPhone, it's easy to find that purpose by retrieving the actual name of the emoji in Apple's operating system.
Apple's Always-On display feature for the iPhone 14 Pro and 14 Pro Max can show important information on the screen even when the device is sleeping. While the dimmed Lock Screen may seem like a WYSIWYG component, there are actually a few ways you can customize it to fit your needs better.
Your iPhone's Camera app isn't the only place you can use Portrait mode for selfies. An easy-to-miss feature built right into iOS lets app developers leverage Apple's powerful Portrait mode effect in their own apps, so you can add a shallow focus effect to photos and videos when using the front-facing camera in FaceTime and apps like Facebook, Instagram, Snapchat, and Zoom.
Customization has always been the main draw of Android for me, but Apple has an impressive feature on iOS 16 that lets iPhone users create customized emoji wallpapers for their home and lock screens. While Android doesn't have something like that built-in by default, it's easy enough to make emoji wallpapers for your Android phone.
One of the most useful new features Apple included on iOS 16 lets you instantly lift the subject out of a photo, separating it from the background. Once extracted, you can paste, save, or drop the cutout wherever you want as a new image, and you can even make it a sticker in messaging apps.
Have you ever seen an image on social media, somebody's blog, or a news website that shows an iPhone or iPad screenshot with an actual iPhone or iPad model framed around it? You can do that too, and it's really easy to accomplish with a third-party app — but you can do the same thing with a shortcut that won't bug you to pay or subscribe.
While hitting snooze won't help you much if you fall back asleep, it can help you wake up more gently. However, your iPhone's default nine-minute snooze may be too long or too short for your preferences. If you tend to fall back asleep quickly, you might be better with a two-minute snooze.
With a simple web-based tool, you can hide secret messages for family, friends, and fellow spies inside of plain text communications, and anyone that intercepts the messages will be none the wiser.
If you've recently built a Wi-Fi spy camera out of an ESP32-CAM, you can use it for a variety of things. A baby monitor at night, a security camera for catching package thieves, a hidden video streamer to catch someone going somewhere they shouldn't be — you could use it for pretty much anything. Best of all, this inexpensive camera module can perform facial detection and facial recognition!
Apple pushed out the Release Candidate for iOS 14.6 on Monday, May 17. The 18F71 build includes new features and bug fixes, including an option to unlock your iPhone with Voice Control. It comes just hours after Apple announced Spacial Audio and Lossless Audio playback for Apple Music, new features that will require iOS 14.6 to run.
If you buy an Android phone from any of the big US carriers, it will come with several extra apps in addition to any apps the manufacturer preinstalled. It's all in the name of profit, of course. Some of these apps are from companies that paid the carriers to distribute their software, and some are from the carriers themselves, usually aimed at upselling you or perhaps collecting a little data.
MicroPython is an exciting language to use on ESP8266 boards and ESP32-based microcontrollers, but it doesn't always include all of the libraries you'll need for a specific project. This issue is less of a problem, thanks to the upip package manager.
For all of its many perks — from the best iPhone camera system money can buy, to arguably the best smartphone display on the market — the iPhone 12 Pro Max is undeniably huge. It has the largest iPhone screen to date despite being 0.46 cubic inches smaller than the iPhone 11 Pro Max in overall size. If you're finding it a little too much to handle with one hand, there are ways to make it much easier to use.
One thing you can expect from Apple is that big features work right out of the box. The company designs its products to be easy to use for any experience level, so you might expect the same to be true for 5G, one of the biggest selling points for the iPhone 12, 12 mini, 12 Pro, and 12 Pro Max. Yet, you might have trouble getting 5G to work on your brand new iPhone. Here's how to avoid that.
The 2020 Chromecast is full of new features, but one glaring omission is Stadia, Google's cloud gaming platform. The search giant confirmed Stadia wouldn't officially arrive on the new streaming dongle until the first half of 2021 — but there's an unofficial way to get it now.
Your iPhone's new home screen widgets are awesome — until they're not. Photos, in particular, is a big disappointment. It gives you a taste of having your favorite photos appear alongside your apps but ruins it by changing the photo randomly every hour without your input. While nothing can be done with the Photos widget, there is a way to get the pictures you want to see on your home screen.
There are plenty of reasons to upgrade to iOS 14, home screen widgets chief among them. With that in mind, it's ironic that Apple placed so much emphasis on "widgets" this year when the new update removes a fan-favorite widget of the past — the "Favorites" Phone widget, which was accessible via the Today View or quick actions on the home screen. Here's how to get it back.
One of Apple's key features for iOS was always its "what you see is what you get" philosophy. Sure, there were small tweaks and complicated workarounds to customize an iPhone, but, for the most part, all iPhones felt similar. These days, however, changing up your iPhone's look is much easier. In just a few steps, you can change one of the most visual parts about iOS — home screen app icons.
Have you ever watched a video on your iPhone but wanted to look at something else real quick? Before iOS 14, you had to choose between pausing the video or waiting until it's over — not exactly ideal for a device that's supposed to help you multitask. But with iOS 14 or later, we can use picture-in-picture mode to watch and perform other on-screen tasks at the same time.
