Since I first announced the new Null Byte recognition for excellence a few weeks ago, several of you have written me asking, "How can I study for this certification exam, and what material will be covered on the exam?" Now I have an answer for you. The White Hat Hacker Associate (CWA) will cover 14 domains or areas. Everything you need to know is here on Null Byte. There will be no questions that are not covered here on this site, guaranteed.
Like the majestic mountain structure it's named after, Apple's latest version of OS X, El Capitan, goes a little deeper to expand on the foundation laid by Yosemite. While the update may not be as monumental as some have hoped, it is an improvement and includes tons of useful new features you don't want to miss.
Nothing gets me functioning in the morning better than strong coffee. And if I'm going to start my day with a dreaded workout, that steaming cup of caffeine is the exact motivation I need to get going. Although coffee might not seem like the best beverage to drink before hitting the gym, it actually has a few hidden benefits over water that may surprise you.
Hi nullbytes! I've been recently reading the whole Linux Basics for the Aspiring Hacker series and felt like it was missing some stuff I know, so I felt like sharing it with anyone who might find it useful too.
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.
Each flavor of sake, the national spirit of Japan, comes with its own fans, not unlike whiskey aficionados here in the States. While sake is often called "rice wine," it is more akin to a malted beverage like beer.
Lemons and limes might be among the most useful fruits in the kitchen and even beyond. Their bright, tart flavor livens up just about any dish, while their mildly acidic nature makes them incredibly useful when you want to clean your house safely. We already knew lemons were great for keeping fruits and vegetables from turning brown, deodorizing garbage disposals, disinfecting cutting boards, and neutralizing odors. But just when we thought we knew all the ways that lemons can be used around ...
Look on any bistro or pub menu in America and you'll likely find the term caramelized onions as an option for your burger. The word "caramel" may conjure up images of candy, which is somewhat correct.
No one wants to appear stupid. Whether you rely on lengthy, complicated vocabulary to show your smarts, or enjoy highlighting your speedy mental math skills, everyone prefers emphasizing intelligence over hiding it.
Bad news, guys. The shelf life for liquor leftovers does not apply to your two-buck chuck. While an opened bottle of your favorite whiskey will stay respectable for ages thanks to its high ABV (which makes it inhospitable to outside elements), an opened bottle of merlot will sour quickly. However, it turns out that red and white wines have different life spans once they're opened—for reasons which we'll cover below.
MacBooks are built for creation and creativity. They're built to withstand our careers, our hobbies, and our everyday use. I use mine every day, and there's nothing I'd recommend more for computing needs.
Remember the feeling you had the moment you removed your shiny new Nexus device from its packaging and booted it up for the first time? You swiped through the app drawer at lightning speed and thought to yourself, "This is the last Android phone I will ever need, they just aren't going to get any better than this."
We all know that it's important to drink water regularly throughout the day. After all, it has so many benefits, including flushing toxins out of the body and maintaining kidney health and good bowel movements. Turns out that's only part of the story. While being properly hydrated is key to maintaining overall health, it's also a big component of maintaining and even increasing cognitive ability. Plus, drinking enough water regularly can help you lose weight, if you know when to drink it and ...
Welcome back, my fledgling hackers! A short while ago, I did a tutorial on conducting passive OS fingerprinting with p0f. As you remember, p0f is different from other operating system fingerprinting tools as it does not send any packets to the target, instead it simply takes packets off the wire and examines them to determine the operating system that sent them.
Welcome back, my apprentice hackers! As many of you know, I have been hesitant to adopt the new Kali hacking system from Offensive Security. This hesitancy has been based upon a number of bugs in the original release back in March of 2013 and my belief that BackTrack was easier for the novice to work with.
Welcome back, my greenhorn hackers. When Wi-Fi was first developed in the late 1990s, Wired Equivalent Privacy was created to give wireless communications confidentiality. WEP, as it became known, proved terribly flawed and easily cracked. You can read more about that in my beginner's guide to hacking Wi-Fi.
Welcome back, my greenhorn hackers! I've been writing these Linux tutorials in an attempt to fill the void in the education of some aspiring hackers into the Linux operating system. There is a lot to know, and in this tutorial, we'll look at Linux file permissions. Step 1: Checking Permissions
Whenever a friend borrows my Samsung Galaxy S3 to browse the web or make a quick call, I always pause to make sure there's nothing incriminating on it. I'm no superfreak, but some of my friends are, so I have more than a few photos on my device that I wouldn't wish upon anyone. I like to avoid these kinds of looks.
The vast majority of people involved in Steampunk are interested in history but, like with science, there's something about history that we don't talk about very often: The holes.
Caller ID is great to have, but there are certain situations where you don't want the person you're calling to have your number. People who sometimes use their personal phones for work may not want clients knowing where to reach them outside of work, and anytime you're dealing with Craigslist, it's better to be safe than sorry.
If you've never heard of geocaching, it's kind of a grown-up treasure hunt you play everywhere in the world. GPS coordinates are given as clues and the players must find the cache box. There is usually a log book to write your name and a small toy or present to collect.
Tech tends to move forward without looking back, but that doesn't mean new is always better. One feature that dominated mobile phones in the late '90s had made a comeback thanks to Apple, and you can take advantage of it on your iPhone when making calls.
Apple has a secret iMessage effect so hidden that there's only one way to unlock it, and it's not by digging through the Messages app's settings, tools, effects, or interface. However, it's used the same way whether you're messaging from an iPhone, iPad, or Mac, so it's easy to remember once you know.
It's no secret that Apple and Spotify haven't exactly gotten along in the past, but things are looking better than ever in iOS 14.5.
Apple's stock keyboard for iPhone has gone through many changes over the years. Some have been significant, and others more subtle. Overall, most of these updates have been fairly obvious, so you're probably already using them — but there are more than a few interesting features that were slipped in under the radar that you may not know about.
Every now and then, an iOS secret surfaces that makes me wonder, "How am I just learning about this?" I remember the first time I found out how to delete numbers in the Calculator app, and when I discovered you could bulk-move apps around the Home screen. Now, there's another tip to add to the list: a hidden iOS app whose icon you quite literally can't find unless you know where to look.
The average iPhone user has between 60 to 90 applications installed. On one of my devices, I have over 600. With a ton of apps to sort through, it can sometimes be challenging to find the one you're looking for without having to use the Search tool (which is even better in iOS 14). Even then, you may still come up dry.
With Samsung's One UI version of Android, it's easier than ever to take a screenshot and quickly edit the captured image. However, the downside to that convenience has manifested itself in an overlay ribbon that can also get in the way.
Many of us install TikTok just to see what it's like, but most of us stay for good. Inevitably, that involves creating an account. The problem is, TikTok assigns you a username, usually based on your email address — an odd choice for a platform made for self-promotion. If you're not happy with your random TikTok handle, you can change it.
In iOS 11, Apple made it easier for you to share passwords with friends. Back then, it was just Wi-Fi passwords, which made sense. "What's the Wi-Fi?" gets old after a while. But now, whether you're running iOS 12 or 13, you can share any password you want with any iPhone around, all with one of iOS' best features: AirDrop.
Remember when typing without physical keys seemed ridiculous? Now, touch typing is the smartphone norm. That said, mistakes are inevitable on small screens. So before you start hammering on that delete key or shaking your iPhone like a madman, know that there's a better way to undo text you didn't mean to type — no shaking involved.
Facebook Messenger Lite is more than just a battery-friendly version of the full-fledged Messenger app for Android. It's still packing some pretty neat features and it's so much snappier than its bloated counterpart. All of the essentials are present, down to the ability to give your contacts nicknames.
If the name Leroy Jenkins elicits a reaction from you, then you are old enough to remember the iconic title World of Warcraft from its heydey (whether or not you actually played the massively multiplayer online role-playing game).
If you're worried about the security of your Mac, there are easy measures to prevent the most dangerous attacks. Named after the tactic of accessing an unattended computer in a hotel room, we can thwart "evil maid" attacks with Do Not Disturb and LuLu, free macOS tools by Objective-See that keep an eye on unattended computers and flag suspicious network connections that indicate a malware infection.
Like last year's beta release of Android Pie, Google has allowed the Android Q Developer Previews to support some non-Pixel devices. Announced at Google I/O 2019, there are 15 non-Pixel smartphones eligible for the Android 10 Beta, including 2017's Essential PH-1.
You would think that recovering your smartphone or another important item that you leave behind in an Uber ride would be a simple process, but it can actually be a pain in the ass. You have to find out how to report it to the driver, hope the driver is honest, pay a fee, and contact Uber directly if none of that works. But we're here to help make this process as easy as possible for you.
Your social security number, credit card information, and medical history can fall into the wrong hands if you're not careful about how and where you share your data online. If you really care about your data, there are tools and techniques you can utilize to protect yourself from cyberstalkers, advertisers, and hackers in a time when digital lives are a high commodity.
The New York Times has made a habit of publishing augmented reality stories throughout 2018, and now the media giant's magazine is getting into the act, too.
Over the years, Magic Leap's long-cultivated shroud of mystery led some onlookers to buy into the company's dream before even trying the device, while for others, the secrecy seems to have stoked the kind of resentment and overcorrecting critique usually reserved for the mighty Apple.
It's not uncommon for hackers to attempt to move laterally between devices in proximity of a compromised device to maintain a prolonged presence in the network. Malware utilizing USB flash sticks to self-replicate and compromise air-gapped machines isn't a new concept.
