Smartphones and other Wi-Fi enabled devices send radio signals called probe frames to locate nearby wireless networks, which makes them easy to track by listening for their unique MAC address. To show how this kind of tracking works, we can program a NodeMCU in Arduino to sniff the air for packets from any device we want to track, turning on an LED when it's detected nearby.
Just like cash, bitcoin is used for everything from regular day-to-day business to criminal activities. However, unlike physical cash, the blockchain is permanent and immutable, which means anyone from a teen to the US government can follow every single transaction you make without you even knowing about it. However, there are ways to add layers of anonymity to your bitcoin transactions.
I was in college, and my 15-inch Sony Vaio laptop was my prized possession. It was my first PC and probably the most important thing I brought with me to my dorm — it was both how I completed my assignments and my primary source of entertainment. How could it turn its back on me in my time of need?
One of the most exciting additions to iOS 12 for iPhones is called Shortcuts, a tool integrated with Siri to help you get things done faster.

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.
Kali Linux is established as the go-to operating system for penetration testing, but in its default configuration, it's less than ideal for regular desktop use. While in many scenarios, a live boot or virtual environment can resolve these issues, in some situations, a full installation is better. A few simple changes can be made to a Kali Linux desktop to make it safer to use in this environment.
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.
A powered-off Windows 10 laptop can be compromised in less than three minutes. With just a few keystrokes, it's possible for a hacker to remove all antivirus software, create a backdoor, and capture webcam images and passwords, among other highly sensitive personal data.
Conducting phishing campaigns and hosting Metasploit sessions from a trusted VPS is important to any professional security researcher, pentester, or white hat hacker.

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.

In just a few months, Binance has experienced explosive growth, overtaking its rivals to rank among the top three cryptocurrency exchanges in the world by trading volume.

Over the years, the internet has become a dangerous place. As its popularity has increased, it has attracted more hackers looking to make a quick buck. However, as our dependency on the web grows, it becomes increasingly difficult to sever all ties. This means we have to protect one of our weakest points, the password.
The Play Store hasn't been the most secure place for apps lately. A quick Google search for "Play Store malware" will give you a taste of some of the malicious apps that snuck their way onto Android's official app store. Google is aware of the problem and they're tying to fix it, but their new Play Protect program doesn't have a great track record, so you might want to look elsewhere.
Word games can expand your vocabulary skills in all sorts of exciting and creative ways. Because of this, both the iOS App Store and the Google Play Store are awash with word games, making it hard to differentiate between good and bad titles.

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, broadcast an FM radio signal, and apparently even fly a goddamn missile into a helicopter.
If your phone has an unlocked bootloader, you can use Fastboot commands to flash factory images. That may sound like a bunch of technical jargon, but when it comes down to it, this is the best method for updating a rooted device, fixing a bricked phone, reverting to stock, or even getting new Android updates before everyone else.
Welcome back, my fledgling hackers! Hacking has a long and storied history in the U.S. and around the world. It did not begin yesterday, or even at the advent of the 21st century, but rather dates back at least 40 years. Of course, once the internet migrated to commercial use in the 1990s, hacking went into hyperdrive.
The software released in the 2015 iterations of the Samsung Galaxy line of devices—the S6, S6 Active, S6 Edge, S6 Edge+, and Note 5—have some pretty neat camera features that give these devices arguably the best smartphone camera on the market today.

I don't know how many of you had this experience in your youth, but when I was a kid, I used to actively think about what would happen if I suddenly woke up in a fantasy land, or were to pass through a portal into another space and time. I knew it wouldn't really happen, but when you're a kid, these can be important issues to you. So I slept with my glasses on every night, just in case. Photo from George Pal's The Time Machine.
One of the hardest, most intimidating parts of making your own Steampunk guns from scratch is the wooden stock of the gun. To be fair, it's probably the hardest part. It requires the most artistry, and is the easiest to mess up.
In the first part of this two-part guide, I covered cutting, grooving, beveling, making holes, and stamping/tooling. I hope you enjoyed that part, because we're pushing the accelerator to the floor and moving ahead at full speed!

Gaming on smartphones has grown considerably since the days of The Impossible Game and original Temple Run. Mobile games can be just as in-depth as console and PC video games, but some of those require external controllers for the best gameplay possible. One controller you can use is the PlayStation 5's DualSense wireless controller, and it pairs nicely with most Android devices.'

The recent announcement that Facebook will begin inserting advertisements into its VR experience on its Oculus Quest headset has set the VR and augmented reality industry into a frenzy.
When smartphones were first getting popular, apps were much more limited in scope. Because of that, it was easier to find better programs to do what was needed. Now, in the App Store alone, there are nearly two million apps for you to choose from. When you're just looking for an app that will work well for the task at hand, two million is a lot to sort through.
The Apple Watch is rapidly becoming a standalone device that you can use without an iPhone or internet connection, and Deezer and Spotify have just helped make that even more true by adding support for offline playback on the watch.

Most iPhones are more than capable of shooting crispy, high-quality video, perfect for any TikTok account to use. But if you're serious about the platform, especially in the long-run, you don't want just any iPhone. Instead, you'll want to pick up an iPhone 12 Pro or 12 Pro Max.
At launch, Chromecast with Google TV is fairly limited in the number of compatible apps. Many of the usual suspects are there, but there are some interesting omissions, like Google Stadia (though support is coming). However, at its core, the device runs on Android 10, which means you can sideload apps, including those that don't officially support Chromecast with Google TV.
With bans looming or already happening across the world, TikTok still remains one of the most popular, entertaining, and addicting apps you can download right now. The problem is, browsing TikTok can be a bit painful at night since everything outside of the video feed uses a bright white theme. Thankfully, dark mode for TikTok is here, but there's a catch.
Lossless quality isn't for everyone. If you can't distinguish between lossless audio and other formats, you probably but don't need it.

And you might not know it, but the Voice Memos app on your iPhone supports it.

If you want to only use the mic from one 'Pod or the other, there's a way to do that.
