Control Computer Using

I obviously do a lot of Steampunk projects, but there are a ton of things out there that I haven't tried yet. So, in an effort to broaden my horizons, I recently taught myself how to use Arduinos, which I plan to incorporate into some of my future Steampunk builds. Since ther ...more

Welcome back, my tenderfoot hackers! A number of you have written me telling me how much you enjoy the Mr. Robot series on USA Network. I am also a huge fan! If you haven't seen it yet, you should. It may be the best show on TV right now. Mr. Robot is about a young man with ...more

Hackers and makers are often grouped under the same label. While hackers draw on computer science skills to write programs and find bugs, makers use electrical engineering to create hardware prototypes from microprocessor boards like the Arduino. We'll exercise both sets of sk ...more

Apple's macOS operating system is just as vulnerable to attacks as any Windows 10 computer or Android smartphone. Hacker's can embed backdoors, evade antivirus with simple commands, and utilize USB flash drives to completely compromise a MacBook. In this always-updated guide, ...more

Generally speaking, in terms of modern devices, the more simple you make an interface to navigate, the more successful the product is. The product could be a coffee maker, an electric piano, a smartphone, or computer operating system. This very idea was one reason that Window ...more

Every Windows system includes command prompt; and while a lot of people on Null Byte and WonderHowTo in general know how to use it, some people don't know anything about it, even how to access it. Even if you aren't a Windows user, it's good to know how command prompt works b ...more

This tutorial was written with Windows 7 in mind, but the principle applies to all versions starting from 7. User Account Control (UAC) Processes in Windows run at different levels of integrity, representing the different amounts of "trust" they have to interact with the com ...more

The Pi-hole project is a popular DNS-level ad blocker, but it can be much more than that. Its DNS-level filtering can also be used as a firewall of sorts to prevent malicious websites from resolving, as well as to keep privacy-killing trackers such as Google Analytics from eve ...more

Remembering keyboards shortcuts can prove difficult, especially when there are so many to remember, not to mention that they differ from app to app. While tools like CheatSheet can make them easier to use, today I'm going to show you how to enter them without using your keyboa ...more

If you're a user of Google Play Music, but not a fan of being relegated to a browser tab, I've got you covered. Developer Sajid Anwar has created a desktop client for Google's music service, but since he made no attempt to hide logos and trademarks, it may not be long before t ...more

For anyone interested in using cheap, Wi-Fi-connected microcontrollers like the ESP8266, the Arduino programming language can be a barrier to entry. Based on C++, Arduino requires knowledge of more computer science than languages like Python. Fortunately for beginners, setting ...more

When you're out and about in the dangerous world of Wi-Fi, it's hard for the average computer user to stay protected, or even know what being protected entails. Little do most people know, Windows 7 has a built-in security that few people take advantage of: a VPN (Virtual Priv ...more

I love surprises. Surprise parties, surprise visits, surprise Patrick... But there are times when a surprise is the last thing you want, like reaching into your pocket to find that your Samsung Galaxy S3 is not where it should be. Having your phone stolen used to be the end o ...more

If you're using iOS 10 or lower, there is no built-in way to record an iPad, iPhone, or iPod touch screen, and Apple doesn't allow any third-party apps to screen record either. If malicious, an app could theoretically continue recording even after you think it's off, allowing ...more

When the Steam Link app was first introduced in 2018, I was impressed. As long as you were on the same network as your PC, you could play your Steam games on your phone. But now, it's even more impressive. By enabling a few extra settings, you can play your Steam library on mo ...more

Just like Apple and Google, Facebook has been working to develop computer vision shortcuts designed to give mobile apps augmented reality superpowers. And while Apple's ARKit and Google's ARCore use computer vision to guess the position of horizontal and vertical surfaces, Fa ...more

Back in the eighties, I used to hate television commercials, but I eventually got used to them. Had to, in order to enjoy my favorite shows. Then, the increasing number of billboard ads annoyed me in the nineties. They followed me everywhere I went—no escape—persuading me to b ...more

All of Apple's products are praised for being extremely easy to use. So much so, that your grandma can pick one up and be a "pro" within a few hours. However, this isn't necessarily a good thing for us real power users who want more granular control of our devices. Luckily, M ...more

With just one line of Ruby code embedded into a fake PDF, a hacker can remotely control any Mac computer from anywhere in the world. Creating the command is the easy part, but getting the target to open the code is where a hacker will need to get creative. Ruby is just one wa ...more

The Raspberry Pi is a credit card-sized computer that can crack Wi-Fi, clone key cards, break into laptops, and even clone an existing Wi-Fi network to trick users into connecting to the Pi instead. It can jam Wi-Fi for blocks, track cell phones, listen in on police scanners, ...more

As someone with a pretty nice TV, I've never found the allure in purchasing a projector. While they're certainly smaller and sleeker than a television, and more portable, they can be pricey and produce a less than stellar image. And who really buys a projector anyways? They're ...more

Hello all, this is my first submission to null byte! I noticed something a little strange, particularly that whenever Meterpreter is discussed, it is virtually always in the context of Windows. Granted, the Windows Meterpreter is more powerful than the version that can run on ...more

There are already a few ways to use your home computer on the go, but none of them feel very natural when you're out and about, and are clunky options at best. Samsung wants to change that with Monitorless, their upcoming augmented reality smartglasses, which offer remote desk ...more

Your iPhone comes packed with a long list of excellent text tones to choose from. Bamboo anyone? Of course, for some of us, stock sounds from 2013 don't cut it anymore. We want customizability, something that's found more on Android than iOS. However, you can add your very own ...more

It would only make sense that Google is one of the most active app developers on the Android platform, particularly when you consider that they develop the platform itself. From my count, there are an astounding 117 unique apps that the search giant and its subsidiaries have p ...more

In 2019, the Raspberry Pi 4 was released with specs including either 1 GB, 2 GB, or 4 GB of memory, a Broadcom BCM2711B0 quad-core A72 SoC, a USB Type-C power supply, and dual Micro-HDMI outputs. Performance and hardware changes aside, the Pi 4 Model B runs Kali Linux just as ...more
