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.
Welcome back, my greenhorn hackers! As hackers, we often take for granted that nearly all of our hacking tools and operating system are free and open source. I think it's important to examine a bit of background on how we arrived at this intriguing juncture in the history of computer software. After all, we pay for nearly all of our other software (Microsoft, Adobe, etc.) and nearly everything else we use in life, so how is it that Linux and all our hacking tools are free?
Even if you're a good cook, sometimes home-cooked food just doesn't taste the same as it does in a restaurant. Of course, there are some utensils and appliances in a professional kitchen that the average person doesn't have access to, but it's not just about the tools.
Despite some of the biggest players in tech still lagging in terms of offering smartglasses options, there are nevertheless a number of smartglasses makers, including North and Vuzix, with consumer-grade smartglasses on the market right now.
The pictures we upload online are something we tend to think of as self-expression, but these very images can carry code to steal our passwords and data. Profile pictures, avatars, and image galleries are used all over the internet. While all images carry digital picture data — and many also carry metadata regarding camera or photo edits — it's far less expected that an image might actually be hiding malicious code.
Greetings my fellow hackers.
If you haven't read the last article, feel free to stop by and give it a read, but abstaining from reading it will not, for the most part, be detrimental to your understanding.
Welcome back, my tenderfoot hackers! As hackers, we often are required to get past antivirus (AV) software or other security measures. To do so effectively, we need to have some understanding of how AV software works. In this tutorial, we will take a cursory view of how AV software works so that you can better strategize on how to evade detection by it.
People who know that I am a professional hacker often ask me what they can do to make their computers and personal information safe from people like me. The answer, of course, is that nothing will make you completely safe, but there are a number of measures any computer user can take to reduce the chances of being a victim of a hacker.
It has been a long while since I last came here to write an article. Graduate school keeps you busy. After I looked over what I had written previously, I decided that I should introduce another fun topic from cryptography. In this case, steganography.
The world of Lego is timeless primarily because everyone, regardless of age or background, can build a wide variety of amazing things with the simple component blocks from the classic toymaker.
You may be familiar with image-based or audio-based steganography, the art of hiding messages or code inside of pictures, but that's not the only way to conceal secret communications. With zero-width characters, we can use text-based steganography to stash hidden information inside of plain text, and we can even figure out who's leaking documents online.
If you're using a mobile device, it's a pretty safe bet that your apps are sending lots of information back and forth from their servers. To make sure there is no inappropriate data collection going on, it's worth setting up a web proxy to spy on this traffic, so you know exactly which apps are "phoning home" and when.
Kali Linux is the obvious first choice of an operating system for most new hackers, coming bundled with a curated collection of tools organized into easy-to-navigate menus and a live boot option that is very newbie-friendly. But Kali isn't the only distribution targeted at pentesters, and many exciting alternatives may better fit your use-case. We've already covered BlackArch Linux, now it's time to talk about Parrot Security OS.
In the aftermath of the unindicted police killings of Michael Brown and Eric Garner, we've been told that the system worked as intended. When our legal system's outcome is at conflict with what a majority of Americans believe is just, it's clear that some changes are needed. But what specifically needs to change? And what can an average citizen with a moral and just cause do to prevent these kinds of tragedies from repeating themselves again and again?
Like theme music, I always feel that I need more fog in my life. Fog can be useful for many reasons—warding off smaller siblings from your bedroom, keeping curious hands out of your cupboard, and tricking your friends into thinking there's something horribly wrong with their vehicle. So, today we'll be making a very simple fog machine for small scale applications.
In less than a month, WWDC, Apple's Worldwide Developers Conference, will reveal the company's plans for the upcoming iOS 18 and iPadOS 18 software updates. But we already know what accessibility features will be hitting iPhones and iPads later this year, and many of them will be helpful to everyone, not just users with accessibility issues.
Apple's iMessage is one of the main reasons to use an iPhone, and there's a lot you can do in chats without being overly complicated. But there's one issue that continues to drive people nuts, and that's the blue typing bubble indicator with the moving ellipsis (•••). Can you stop it? Not officially, but there are workarounds.
If you have Snap Spectacles 3, the dual camera-equipped sunglasses capable of capturing 3D photos and video, by now you've likely jazzed up the videos you've captured on the wearable with Lenses via Snapchat.
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.
On April 26, 2019, Sinemia posted a note on its website stating it has ceased all operations in the United States. It's not known if it continues to work in other countries or if US users will be getting any refunds, particularly, for annual subscribers.
You can mod every aspect of your phone's software with root, but if you want to make changes at the hardware level, you'll need a custom kernel. If you've looked into custom kernels before, one name undoubtedly kept coming up: ElementalX. It's easily the best custom kernel out there, and the reason for that is its awesome developer, flar2, aka Aaron Segaert.
Many lazy cooks skip rinsing off their grains before they cook 'em, but that's a big mistake for a few reasons. Some grains have coatings on them that need to be rinsed off to cook properly and taste good.
Thought I would cross-post a piece I did a while ago.
When you enable Low Power Mode on your iPhone, it's not always clear what measures it's taking to reduce battery drain and conserve power. Changes to energy-hungry features you use daily may be immediately noticeable, but some things you frequently use may be disabled or reduced without any apparent indicators.
The year 2020 was a pivotal span of time during which the word "virtual" took on a brand new meaning. Instead of referring to VR or augmented reality, the term was hijacked to describe meeting across long distances through a variety of software tools, most often through video.
