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.
Welcome back, my hacker apprentices! Last week, I started off my password cracking series with an introduction on the principles and technologies involved in the art of cracking passwords. In past guides, I showed some specific tools and techniques for cracking Windows, online, Wi-Fi, Linux, and even SNMP passwords. This series is intended to help you hone your skills in each of these areas and expand into some, as yet, untouched areas.
The Paris-based technology conference Viva Technology, which hosted the likes of Apple's Tim Cook and Facebook's Mark Zuckerberg, is now over.
The last few weeks were fairly busy in the realm of augmented reality and remote meetings developments. Most of that activity was generated by some mammoth announcements from Snap and its Spectacles AR smartglasses, and Google, with its Project Starline experimental holographic video conferencing system.
The experience of actually using the HoloLens 2 can be difficult to describe to anyone who hasn't had a chance to directly interact with the device in person and be blown away by its immersive capabilities.
The COVID-19 pandemic has increased the demand for virtual and remote collaboration, and Microsoft has a solution that may serve as the catalyst for more such apps for augmented and virtual reality in the near future.
The past year has revealed a gaping hole of opportunity in the world of business called virtual meetings. Some existing players like Zoom hopped on that opportunity, while others like Skype seemed stuck on the sidelines, and Google Meet just managed to catch up in time to snag some of the shift in remote work.
You won't have to ask Santa for holiday-themed augmented reality experiences, because practically any social and shopping app that offers AR effects has them available now.
When learning Wi-Fi hacking, picking a compatible Wi-Fi network adapter is the first step to learning to crack Wi-Fi passwords.
As government officials scramble to contain the new coronavirus outbreak with bans on large gatherings, travel restrictions, and school closures, the rest of us have to worry about how we're going to safely purchase water, toilet paper, groceries, and other household goods during the global COVID-19 pandemic.
When Facebook launched its first hardware products last year, the Portal and Portal+ smart displays, the company mostly touted its video-calling features as it faced off against Amazon and its Echo Show.
If you want to carry a variety of network adapters without looking suspicious, a perfect solution is accessing them through Airserv-ng. Tucked away in the Aircrack-ng suite, this tool allows a hacker to plug any number of network adapters into a Raspberry Pi and access them over a Wi-Fi or Ethernet connection.
With a tiny computer, hackers can see every website you visit, exploit services on the network, and break into your Wi-Fi router's gateway to manipulate sensitive settings. These attacks can be performed from anywhere once the attacker's computer has been connected to the router via a network implant.
Setting up a new Android phone can be a pain. Although Google has some automated features, it does not restore everything. When it comes to transferring certain types of data like files and SMS logs, it's even trickier. By following our steps, you can be sure that you all your data will follow you to your new device.
Security-minded users can reduce the risk of phishing by enabling Advanced Protection on important Google accounts, requiring a U2F security token to log in. Using these keys isn't intuitive on most popular smartphone platforms, and you can find yourself locked out if you don't plan ahead. You'll need to learn and practice using U2F keys on your device before enabling this layer of security.
Threats to your privacy and security are everywhere, so protecting your data should be the highest priority for anyone with a smartphone. However, one threat many people overlook is the company who supplies the operating system your Android phone runs — Google.
In October of 2017, Mathy Vanhoef released "Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2." This paper demonstrates a way to decrypt traffic on practically any WPA2 network, the most commonly used form of wireless security (seeing as all other forms of Wi-Fi encryption have already been broken). Practically all of the network-connected devices we use will need to be updated in some way in order to protect against this vulnerability, each of them in a different way.
When we are building programs that communicate over a network, how can we keep our data private? The last thing we want is some other lousy hacker sniffing our packets, so how do we stop them? The easy answer: encryption. However, this is a very wide-ranging answer. Today we're going to look specifically at how to encrypt data in Python with dynamically generated encryption keys using what is known as the Diffie-Hellman key exchange.
Walsh, a new community under construction on 7,200 acres of former ranch land near Fort Worth, Texas, will one day contain 15,000 homes.
The Galaxy S8 has finally touched down, and it's an absolutely gorgeous device. Samsung's brand new flagship comes jam-packed with new features — some refined, and some that aren't. Luckily, we've compiled some major features to help you get started as quickly as possible so you can go about the rest of your day and show off your shiny new S8 to friends and coworkers.
For years, smartphone makers have been caught up in a megapixel spec race to prove that their camera is better than the next guy's. But we've finally come to a point where even the lower-end camera phones are packing more megapixels than they need, so it's getting harder to differentiate camera hardware.
I've been an Android user almost as long as the operating system has existed, so when I received my first iPhone in April, I felt like I was in a foreign land. Sure, it runs most of the apps I'm used to, and the phone itself feels about the same in my hand as any similarly-sized device, but everything else is just different.
Today's smartphones and tablets offer a great way for children to learn through interactive sight, sound, and touch, but they can also provide hours of genuine fun. If you have a spare tablet laying around—or at least a nice, durable case—the only thing you need to get your child started in this world of fun and learning is a handful of good apps.
Smartphone games are getting pretty good these days, but they still can't beat the retro appeal of a good emulator. I mean, who wouldn't want to have their all-time favorite console and arcade games tucked neatly in their front pocket? Classics ranging from Super Mario Bros. to Pokémon can all be played at a silky-smooth frame rate on today's devices if you can just find a good emulator to run them on.
The ability to make a meal for yourself used to be one of those life skills you had to learn or otherwise you would starve, but the rise of convenience foods, takeout, and other aspects of modern living have made it entirely possible to be a grown person and not know what to do in the kitchen.
I am an English major physically allergic to all algebraic formulas, so you're unlikely to get any help from me when it comes to solving any expressions. But in the glorious technological age we live in, there are plenty of apps that actually make math and problem solving fun, even a little bit addictive.
I love cryptography. It is like a great gigantic puzzle for me to solve. However, it is more important than that. It is also how we keep secrets safe. Not just sorta safe either, but really safe.
I admit, when the new iOS 5 update for Apple devices was coming out, I had iTunes open all morning with my iPhone 4 attached... waiting... waiting... waiting until finally the new version of iOS was available for download. I stopped everything I was doing and quickly initiated the process of updating my device. After two excruciating hours, my iPhone 4 was finally ready to go and I couldn't be anymore happy. Who needs an iPhone 4S when you've already got iOS 5?
In Android 11, music player controls have been moved from the notification tray to the Quick Settings. The change frees up space for the new Conversations notification section. It also adds media output controls, making it possible to switch from your phone speakers to a Bluetooth device with only two taps.
People fundamentally distrust magicians. And they should. The illusions they proffer are just that, illusions meant to astound rather than tangible interactions and results that have weight and meaning in our real world. Our lizard brains know this, and, no matter what the outstanding feat of "magic" presented, we nevertheless hold fast to our survival-based grip on the truth: we just saw simply "can't be real."
TouchWiz might not be the Android skin of choice for hardcore aficionados, but the Galaxy's OS still has a ton of great features up its sleeve that help provide one of the most enjoyable smartphone experiences out there. Many of these are relatively hidden and overlooked features that you may not be aware of.
They're finally here — Samsung has officially revealed the Galaxy S9 and S9+, which run Android Oreo out of the box. Since we've spent plenty of time with the Oreo beta for the Galaxy S8, we already know about some of the best new software features coming to the Galaxy S9. Like previous updates, Samsung has enhanced its software with a fresh look and brand new functionality.
Samsung has finally rolled out the Android Oreo update for the Galaxy S8 and S8+. If you're just now getting the update, you'll be happy to know that your Galaxy just got upgraded with plenty of cool new features. Like previous updates, Samsung has improved upon its software by including a new look and new functionality.
Now that smartphones have ensured that we're connected to the internet 24/7, online privacy has become more important than ever. With data-mining apps hoping to sell your information for targeted ads, and government agencies only one subpoena away from knowing every detail of your private life, encryption has become our last line of defense.
ADB and Fastboot are powerful tools that have always required a computer. But with the right setup, you can now send commands to a phone using another phone.
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.
The Digispark is a low-cost USB development board that's programmable in Arduino and capable of posing as a keyboard, allowing it to deliver a number of payloads. For only a few dollars, we can use the Digispark to deliver a payload to a macOS computer that will track the Mac every 60 seconds, even bypassing security like a VPN.
A good smartphone can be the perfect workout companion. You have music for motivation, videos for pushing through boring cardio sessions, GPS to keep you on course, and even an array of sensors for gathering data about your workout. But not all phones are created equal when it comes to helping you stay fit.
There are times when physically interacting with your iPhone is less than ideal, like when you're cooking or driving. Fortunately, iOS 13 has you covered regardless of the circumstance you may find yourself in. With the new Voice Control feature, you can control pretty much everything on your device without even touching it.
Every summer for the last 26 years, hoards of hackers have descended on the Las Vegas Strip for DEFCON, the biggest hacker conference in the US. There's a wealth of talks every season (DEFCON 27 has at least 95 scheduled), and there have been some essential topics to learn from in past discussions. We've dug through the last ten years and found the 15 most popular talks you should watch.
