In our last ARKit tutorial, we learned how to measure the sizes of horizontal planes. It was a helpful entryway into the arena of determining spatial relationships with real world spaces versus virtual objects and experiences.
Ever notice how some augmented reality apps can pin specific 3D objects on the ground? Many AR games and apps can accurately plant various 3D characters and objects on the ground in such a way that, when we look down upon them, the objects appear to be entirely pinned to the ground in the real world. If we move our smartphone around and come back to those spots, they're still there.
Analysis of photographs and social connections can be a huge component of social engineering. Understanding who a person is, as well as who they know, can establish links within a company. This information could be used by hackers to execute elaborate social engineering attacks.
If you want to follow Null Byte tutorials and try out Kali Linux, the Raspberry Pi is a perfect way to start. In 2018, the Raspberry Pi 3 Model B+ was released featuring a better CPU, Wi-Fi, Bluetooth, and Ethernet built in. Our recommended Kali Pi kit for beginners learning ethical hacking on a budget runs the "Re4son" Kali kernel and includes a compatible wireless network adapter and a USB Rubber Ducky.
Beginners learning brute-forcing attacks against WPA handshakes are often let down by the limitations of default wordlists like RockYou based on stolen passwords. The science of brute-forcing goes beyond using these default lists, allowing us to be more efficient by making customized wordlists. Using the Mentalist, we can generate millions of likely passwords based on details about the target.
While Wi-Fi networks can be set up by smart IT people, that doesn't mean the users of the system are similarly tech-savvy. We'll demonstrate how an evil twin attack can steal Wi-Fi passwords by kicking a user off their trusted network while creating a nearly identical fake one. This forces the victim to connect to the fake network and supply the Wi-Fi password to regain internet access.
After finding and monitoring nearby wireless access points and devices connected to them, hackers can use this information to bypass some types of security, like the kind used for Wi-Fi hotspots in coffee shops, hotels, and in flights high above the ground. By swapping their MAC address for that of someone already connected, a hacker can bypass the MAC filter and connect freely.
Coinhive, a JavaScript cryptocurrency miner, was reportedly discovered on the BlackBerry Mobile website. It was placed there by hackers who exploited a vulnerability in the site's e-commerce software that allowed them to anonymously mine cryptocurrency every time the website was viewed. There's no doubt Coinhive, an innovative mining method, is being abused and exploited by hackers in the wild.
Your home has walls for privacy, but Wi-Fi signals passing through them and can be detected up to a mile away with a directional Wi-Fi antenna and a direct line of sight. An amazing amount of information can be learned from this data, including when residents come and go, the manufacturer of all nearby wireless devices, and what on the network is in use at any given time.
Millions of travelers pass through airports each day without understanding how powerful and insecure a boarding pass can be. Anyone can scan the boarding pass barcode with a mobile app, allowing access to frequent-flyer accounts and even a passenger's temporary airline account. In this guide, we will explore how hackers scan and decode the information contained in a boarding pass barcode and why.
Facebook really wants your phone number, nagging you for one as soon as you join. This isn't all bad since it can help secure your account with two-factor authentication. On the flipside, this makes it easy to reveal the private phone numbers of virtually anyone on Facebook, including celebrities and politicians. We're going to look at how a hacker would do this and how to protect yourself.
If you've never used the Home button shortcuts on your iPhone before, you've been missing out. And no, I'm not talking about opening up Siri. By clicking the Home button three times, you could quickly pull up tools such as Magnifier, VoiceOver, Zoom, and Assistive Touch, but that's all changed on the iPhone X, XS, XS Max, and XR, which don't have Home buttons to click.
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.
On April 7, 2017, residents in Dallas, Texas, woke to the sound of emergency sirens blaring all over the city. No one could shut them off, and after repeated efforts to contain the situation, the city had to shut down the entire system. While the media reported a sophisticated computer hack was responsible, the truth was much less high-tech.

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.
Running out of storage space on your iPhone is annoying, but trying to free some up is downright aggravating. Until they figure out a way to throw a terabyte of flash memory in there, you're going to have to do some spring cleaning every now and then, especially if you're trying to update to iOS 8.
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.
Over the past several weeks, I’ve had the pleasure of test driving Samsung’s next big thing, the Galaxy S4.

You probably receive an overwhelming number of notifications on your iPhone every day — maybe even every hour — which can quickly clutter your lock screen. With Apple's focus on lock screen customization in iOS 16, there are now options that can reduce the screen space that lock screen notifications take up, giving you more room to enjoy all your different wallpapers.
For years, Android has provided easy ways to view all the Wi-Fi networks you connected to in the past, and you can even see the saved passwords in plain text. With iOS 16, Apple finally gave us a similar way to view saved Wi-Fi hotspots, copy their passwords, and remove old ones without being near their access points.
Most of you have probably wondered at least once who has been checking out your social media profiles. While most platforms prohibit you from seeing who's viewed your profile, such as Facebook, Instagram, and Twitter, TikTok is one of the few places that lets you track profile visitors. And unlike with LinkedIn, you don't have to pay for the privilege.
It's easy to start panicking when you delete an important email, but it's even easier to undo the mistake on your iPhone or iPad.

Music goes well with almost every Instagram story, but adding a particular song or soundtrack isn't the most obvious task if you've never tried before or haven't done so in a long time.
Wordle has been popping up all over in the app stores, but none of them are the real Wordle. The popular word game app has amassed two million users since its launch in November 2021 but has no plans to hit the iOS App Store or Play Store any time soon — but you can still install the official Wordle app on the Home screen of your iPhone or Android phone.
If you like to listen to popular songs from huge musicians and hard-to-find music from obscure indie artists, SoundCloud is for you — and you don't have to pay a dime. When you find a song you really love and want to play it back even when you're not connected to the internet, SoundCloud has offline listening, but there is a way to download your favorite tracks onto your iPhone for longevity.
