Everyone from first responders to hotel cleaning staff use radios operating in the sub-megahertz range to communicate, often without even encoding the transmission. While encoding and encryption are increasingly used in radio communication, an RTL-SDR adapter and smartphone are all it takes to start listening in on radio conversations happening around you.
It's easy to run Kali Linux from a live USB on nearly any available computer, but many publicly accessible laptops and desktops will be locked down to prevent such use. School, work, or library PCs can be secured with a BIOS password, which is often an easily recovered default password. Once you have access, though, you can use a USB flash drive to run Kali live on any PC you find.
Defcon is the largest hacker conference with something for everyone, whether it be the talks, parties, villages, or any of the hundreds of events. In this guide, we'll take a holistic view at everything that goes into attending the con for the first time, from securing your electronics and making the most of your time to the logistics of getting there and finding the right place to stay.
Hashes containing login passwords are transmitted between Windows computers on local Wi-Fi networks. By intercepting and decrypting these hashes using Responder and John the Ripper, respectively, we can learn a target's login credentials which can be later used to gain physical access to their computer.
Contrary to popular belief, augmented reality apps have been available for a while now. I remember using the Layar app (still available for iOS and Android) to explore nearby businesses and landmarks with varying success via an early-generation Android handset.
When you tap on a URL link in a text, email, or wherever, your iPhone's default reaction will be to open it up in Safari, and there's no way to change this in the settings. However, there is a way you can work around this to open up links in Chrome instead. Even if you accidentally open a link in Safari, there's a quick way to jump the tab right into Chrome.
Hackers often rely on lazy system admins and unpatched vulnerabilities to get access to a host. Keeping intruders off of our machines requires us to update daily, only run the services we need, and read the code, among other things, but we can still make mistakes. Luckily for us, we can limit the damage caused by those mistakes by running SELinux.
With an ordinary birthday card, we can introduce a physical device which contains malicious files into someone's home and deceive them into inserting the device into a computer.
During our last adventure into the realm of format string exploitation, we learned how we can manipulate format specifiers to rewrite a program's memory with an arbitrary value. While that's all well and good, arbitrary values are boring. We want to gain full control over the values we write, and today we are going to learn how to do just that.
Networking is built largely on trust. Most devices do not verify that another device is what it identifies itself to be, so long as it functions as expected. In the case of a man-in-the-middle attack, we can abuse this trust by impersonating a wireless access point, allowing us to intercept and modify network data. This can be dangerous for private data, but also be fun for pranking your friends.
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.
Your iPhone has a lot of personal information contained within it, so of course you want your device to be secure. You don't want that information getting into the wrong hands — or any hands other than your own, for that matter.
Thanks to ever more powerful smartphones — the iPhone X with its advanced A11 processor and the Galaxy Note 8 powered by Snapdragon's 835 come to mind — the mobile industry is fast closing in on consoles and PCs with regards to gaming. Game developers have been aware of this fact, and have ported many games once dedicated to computers onto our handheld devices.
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 2013, Offensive Security released Kali Linux, a rebuild of BackTrack Linux derived from Debian. Since then, Kali has gone on to become somewhat of a standard for penetration testing. It comes preconfigured with a collection of tools accessible by a menu system, tied together with the Gnome desktop environment. However, Kali Linux isn't the only penetration-testing distribution available.
Aircraft equipped with ADS-B are constantly shouting their location into the radio void, along with other useful unauthenticated and unencrypted data. In this guide, we will make an ADS-B receiver using a Raspberry Pi with a software-defined radio (SDR) dongle, which we can use to track aircraft anywhere in real time.
It's no secret that devices leak data, but sometimes they do so in ways you may not expect. Your phone, laptop, printer, and IOT devices leak Wi-Fi information that can (and is) used to track you.
Quanergy CEO and founder Louay Eldada is, by any standard of measure, a pioneer in the development of LiDARs for driverless vehicles.
While the world is only recently becoming aware of its existence, augmented reality has been around in some form or another since the '90s. In the last decade, with the advancement and miniaturization of computer technology — specifically smartphones and tablets — AR has become far more viable as a usable tool and even more so as a form of entertainment. And these are the people behind mobile AR to keep an eye on.
Being part of the wild frontier is amazing. It doesn't take much to blow minds of first time mixed reality users — merely placing a canned hologram in the room is enough. However, once that childlike wonder fades, we need to add more substance to create lasting impressions.
One of the truly beautiful things about the HoloLens is its completely untethered, the-world-is-your-oyster freedom. This, paired with the ability to view your real surroundings while wearing the device, allows for some incredibly interesting uses. One particular use is triggering events when a user enters a specific location in a physical space. Think of it as a futuristic automatic door.
With any continuously active software, it can start to become fairly complex after a few years of updates. New features and revisions both get layered into a thick mesh of menu systems and controls that even pro users can get bewildered by. If you are new to a certain application after it has been around for many years, it can be downright intimidating to know where to begin.
Since Android is an open source operating system, that means anyone with a little know-how can download, view, and even alter its underlying code base. Manufacturers do it all the time, which is how we end up with skins like TouchWiz and Sense. But when Android's awesome third-party development community gets their hands on this code, we end up with custom ROMs like LineageOS and MIUI.
Unruly customers. Crazy exes. Horrible bosses. When you need proof of insanity or just want it for your records, recording a phone call is a must. Problem is, it's not the easiest thing to do on an iPhone — but it's completely possible.
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.
Welcome back, my rookie hackers! As hackers, we are often faced with the hurdle of cryptography and encryption. In some cases, we use it to hide our actions and messages. Many applications and protocols use encryption to maintain confidentiality and integrity of data. To be able to crack passwords and encrypted protocols such as SSL and wireless, you need to at least be familiar with the concepts and terminology of cryptography and encryption.
Once upon a time in America, there was coffee and there was decaf. That's it. No capuccinos. No espressos. And certainly no Starbucks. Coffee was just coffee, something that you bought at a gas station or donut shop. If you made it at home, it was either in a metal pot or instant coffee.
Instagram introduced Photo Maps back in 2012, a feature allowing users to showcase where they've taken photos and explore where others have been, all through an interactive map.
Staying healthy is a progressive challenge we all face throughout our lives, and figuring out just how to do that can be a challenge when it's not your job. For doctors, however, it is. Here's how they keep themselves healthy day to day.
Keeping data private is vital in the days of smartphones and the free-floating information they carry. Justin wrote a guide on many of the deeply hidden and sometimes concerning privacy settings in iOS 7. Now we're back to cover some of the new (and old) privacy settings in iOS 8 that you need to address right now.
Go to a chain supermarket, and chances are you'll see one type of garlic—maybe two or three if you're lucky. However, there's a mouthwatering slew of Allium sativum out there, far beyond those papery white bulbs most of us encounter at the nearest Stop 'n' Shop.
There are definitely some great things about iOS 7, but like any good piece of software, it's got some things to kink out—and how wallpapers work seems to be one of the biggest issues, since it's so much different than in previous iOS versions.
You saw our post on the 18 coolest new features of iOS 7, but now that you've had a chance to play around with your updated iPhone, it's time to lock it down.
This is a simple pattern, designed to produce a well-fitting mitten. Both the right and left mittens worked the same up to the shaping for the top of the mitten. A slight adjustment for making one right and one left, then they are worked the same. The gusset for the thumb constructed with the increases made in the center of the gusset, rather than on each side. This makes it easy with a minimal amount of counting stitches as you go. I have been crocheting for 56 years. In doing research for w...
Unless you're a high-schooler building a nuclear fusion reactor, the hardest part of a science investigatory project often is coming up with a good idea. You want it to be cool yet feasible, novel but still useful.
Ads aren't the only annoying part of navigating websites in Safari. Colorful banners, autoplaying videos, embedded objects, and other distracting elements can make it harder to read or watch what you want. Although ad blockers are one answer, they only get rid of advertisements, so you'll need something else to remove other irritating elements from your favorite websites.
Apple's Tapback is a great way to react to iMessages you find funny, surprising, confusing, and anything in between. However, in group chats, keeping track of who reacted with which Tapback can be difficult; iOS often just shows you how many people reacted but excludes many of the names. Luckily, there is a way around this — it's just a bit hidden.
Everyone needs a great website. Whether you want to launch the new business you've been dreaming about in 2021, increase your brand's web presence and bring it into the digital realm, or promote yourself and your portfolio, a fully optimized website is the way to do it — and the results can be life-changing.
If running out of battery while out and about weren't bad enough, the experience is a lot more painful if your iPhone has a semi-untethered jailbreak. With that kind of jailbreak, when the iPhone dies, all of the mods will be disabled after the device powers back up. Fortunately, instead of restoring your jailbreak and tweaks manually after recovering from a critically low battery, you can avoid it altogether.
When you're stuck working or learning from home, video meetings can help you stay connected to employers, coworkers, schools, students, and more. And Zoom is the hottest video conferencing service at the moment. While Zoom is easy to use, it does have a fair share of sketchy features you should know about, such as attendee attention tracking.
