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.
Before we dive any further into getting your Mac ready for hacking, I wanted to continue on with the concept of encryption. In the last part, we talked about full disk encryption on your Mac, but now I want to quickly cover the encryption of disk images before we dive into managing passwords, terminal emulators, etc.
These days, there are Android apps for every budget—forgive me if that sounds like a car commercial, but that's just the way things are in the age of the smartphone and tablet. You've got apps that require monthly subscriptions, paid apps that will run you a $30 one-time installation fee, and even games that start at 99 cents, but quickly skyrocket in price with in-app purchases.
Welcome aboard my inquisitive comrades. I am starting a new series that nobody expected coming. It may not seem very exciting at first, but await the last few parts as many startling discoveries will be made. This is a series which I plan to continue after the completion of Nmap, unless you have major objections.
Before I continue with a topic on strings, we first require some fundamental understanding of how memory works, i.e. what it is, how data looks in memory, etc. as this is crucial when we are analyzing vulnerabilities and exploitation. I highly suggest that your mind is clear and focused when reading the following article because it may prove to be confusing. Also, if you do not understand something, please verify all of your doubts, otherwise you may not completely understand when we touch on...
Smartphones are almost always connected to the internet, so it stands to reason that they can be hacked remotely. Or perhaps a jealous boyfriend or girlfriend got hold of your device physically, in which case they could've potentially installed a keystroke logger, a virus, or any other type of tracking app to spy on you.
Hello fellow training hackers. I do not know if many of you are familiar with ruby, but since it is a useful scripting language, that hasn't been covered too much here on Null Byte, I thought why not do some How-tos about it now and then.
If you're having a "Netflix and chill" night, the last thing you want to worry about is finding something to watch—after all, you have better things planned for the night.
As a hacker or an aspiring one, You need to be careful and anonymous if your doing anything illegal. But you slipped up. Now someone is tracking you! Well luckily you read this post ahead of time and have a backup plan!
Throwing a party means making sure everyone has fun, but that pursuit can quickly get out-of-hand. Before you know it, you're once laid back get-together has received so many RSVPs that it becomes obvious you're throwing the party of the century. With an over-abundance of beer and an inflated guest list, your newly-formed epic reputation must live up to the hype.
We've showed you how to make Butterfingers and Kit Kats, as well as custom-shaped chocolates, but have you ever thought about making your own gourmet chocolate bars?
The drinking straw isn't just there to help you make annoying noises when you get to the bottom of your soda. That little tube of plastic is extremely versatile and can make your life a lot easier with a little know-how. Curious? Read on to find out more.
Straight out of the box, the Nexus 5 is an awesome device, but even it can be faster with better battery life. Luckily, one of the things that makes it so awesome is that there are tons of developers creating mods for it, since it runs stock Android by default. When it comes to gaining speed and better battery life, flashing a custom kernel is the way to go.
Autumn is a time of year when everything looks, smells, and tastes good. The scents of cinnamon and spices are everywhere you go, and even the dead leaves that fall off the trees are pretty. In particular, the fruits and vegetables of the season are gorgeous.
Automation is everywhere in our daily lives. Faucets and hand dryers that turn on for you when they detect your presence. Automated teller machines to handle your bank account. Timed sprinklers to water your lawn every morning. DVRs to record your favorite TV shows when you're not home.
Cryptography is the science of keeping secrets, or more specifically, the science of disguising them. As a point of fact, cryptography has progressed quite a bit farther and now encompasses file and message integrity, sender authentication, and pseudo-random number generators.
Now that iOS 7 is out, what can you do that you couldn't do before? In this softModder guide, I'm going to cover all that's new and noteworthy about iOS 7. I've been playing around with it on my iPhone 5 since the first beta came out, so I'm excited to show you some of the secrets that are lurking within Apple's newest mobile operating system.
It may not be as large as the Samsung Galaxy Note 2, but the Galaxy S3's screen size is still big enough to make iPhone owners cry themselves to sleep. The 4.8-inch AMOLED display with 720 x 1280 pixels makes the GS3 a great mobile companion—and an even better portable gaming device.
The airline is not your friend. It will do anything it can to gouge your dignity, time, and most of all, money. One of the biggest scams to get a few extra bucks out of you are those dreaded baggage fees. If the lines, security, "random" screenings, and unwanted fondling aren't bad enough, you have to pay them to check your bags (which, most of the time, is done poorly). Flying truly is the most inconvenient way to travel.
In Minecraft, many people enjoy "Faction" aka "Raiding" multiplayer servers for their unique gameplay and survival aspect. Plus, it's always fun when you find a chest full of somebody else's free stuff.
There was recently a case that came to national attention where a gentleman was arrested at an airport for having a watch that looked like a bomb, among other things. As it came out, the watch was, in fact, not a bomb, and the man was just an artist who was probably trying to make a statement of some sort. Well, that message was lost amongst the hail of people shouting that either he had been stupid for bringing that watch on the plane and so deserved to be arrested, or that it's a free count...
In the first part of this series, we took a factual and technical look at the history of the Internet. I explained how all of these wires and servers got here in the first place. Obviously, a firm did not just create and build the Internet around 1995! Now that we know how the Internet came to be, we can get into the really fun stuff—what the Internet looks like now! Well, that's not quite the network design I was talking about, but it does show what the Internet looked like back in 2007 befo...
Apple's Messages app already has a ton of great features, from audio message transcriptions to message editing and screen effect triggers. But there are some important new changes to go along with the newest software updates for iPhone, iPad, and Mac that make Messages even better.
Things just got a lot better in your iPhone's Messages app, and the most significant change lets you text Android users with iMessage-like features such as typing indicators, read receipts, large file sharing, high-quality photos and videos, and even emoji reactions.
Your iPhone is fairly secure by default, but Apple's Lockdown Mode takes it to Fort Knox levels of protection. If you're a high-value target for spyware, phishing attempts, and other sophisticated cyberattacks, it's an essential feature. But for almost everyone else, it's an extreme move. If you simply want to verify someone's identity when chatting, Contact Key Verification is a more practical option.
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.
While you can quickly see the edit history of a modified iMessage in the Messages app, there's no way to view an iMessage that somebody in the conversation deleted unless you happened to see it before it disappeared. But that's only true if you didn't implement these security measures on your iPhone.
The Messages app for iOS and iPadOS has a lot of hidden features, but one in particular can save you time and energy whenever you need to forward or copy and paste messages from within an SMS, MMS, or iMessage conversation.
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.
If you were to summarize the path Snap has taken towards augmented reality smartglasses with a meme template, how it started would be the first-generation Spectacles camera glasses and how it's going would be the next-generation Spectacles with AR capabilities.
Ever since Snapchat rebuffed its acquisition attempts, Facebook has morphed Instagram with features from Snapchat, such as stories, chat, and, of course, augmented reality.
The era of virtual meetings has been evolving every few months, with augmented reality filters leading the charge in changing the way we interact when chatting via video streams.
The NFT space is moving so fast that if you're not already engaged, you've probably already missed several history-making events.
Google My Business lets you connect with customers across Google Search and Maps through a unique business profile. The web app allows you to connect and chat with customers in real-time and provides rich analytics to help you manage and grow your company.
It's incredible what technology can do these days, but sometimes, it gets a little scary. For instance, FaceTime's "Eye Contact" feature, which Apple beta-tested in iOS 13 but released with iOS 14, makes it appear like you're looking right at the camera, even when you're actually looking at your friend on the screen. If you find this artificial trick a bit creepy, rest assured you can turn it off at any time.
If you've ever received an email only to focus on the sender's signature — the hi-res image, the sharp design, the vibrant colors — you're not alone. Humans are visual creatures, and with something as ubiquitous as emails, it helps to stand out.
If you're a hacker, pentester, or any other type of Null Byte reader, and would like to create a website to showcase your services and skill set, you may not have the time or energy to do it the long way.
Apple's big iOS 14 update includes Memoji improvements such as new hairstyles and headwear to choose from for your personalized Animoji character. Even better, there are now face coverings, so you no longer have to resort to that one masked emoji to get the point across in these times of COVID-19.
SSH, or the secure shell, is a way of controlling a computer remotely from a command-line interface. While the information exchanged in the SSH session is encrypted, it's easy to spy on an SSH session if you have access to the computer that's being logged in to. Using a tool called SSHPry, we can spy on and inject commands into the SSH sessions of any other user logged in to on the same machine.
