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.
Bluetooth Low Energy (BLE) is the de facto wireless protocol choice by many wearables developers, and much of the emerging internet of things (IoT) market. Thanks to it's near ubiquity in modern smartphones, tablets, and computers, BLE represents a large and frequently insecure attack surface. This surface can now be mapped with the use of Blue Hydra.
On July 20, 1969, humans set foot on the moon for the first time. But some say our microbes beat us there. With the Space Age came new questions about microscopic invaders from outer space and concern about where we are leaving our microbial footprints. The questions are even more relevant today.
Tony Parisi, the global head of VR/AR at Unity Technologies, has been passionately working with virtual and immersive spaces for a long time. And while the internet world we live in now is very different than when Parisi was co-authoring VRML (Virtual Reality Modeling Language) — an early attempt at creating 3D environments that would work in a web browser — some of the questions that were assumed answered are being asked again.
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 world is full of vulnerable computers. As you learn how to interact with them, it will be both tempting and necessary to test out these newfound skills on a real target. To help you get to that goal, we have a deliberately vulnerable Raspberry Pi image designed for practicing and taking your hacking skills to the next level.
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.
While the USB Rubber Ducky is well known by hackers as a tool for quick in-person keystroke injection attacks, one of the original uses for it was automation. In this guide, I'll be going the latter, explaining how we can use it to automate Wi-Fi handshake harvesting on the Raspberry Pi without using a screen or any other input.
Kuru is called the shaking disease, its name derived from the Fore word for "to shake." Caused by an organism that infects the part of the brain that controls coordination, people afflicted with kuru shake uncontrollably.
What happens when a entrepeneur/theme park creator and special effects artist/magician team up? You get a team crazy enough to create the first true virtual reality theme park (sorry, Six Flags). They only have a single experience so far, but it's already taken a giant leap beyond the wonders we've seen in today's consumer virtual reality headsets.
There's a common saying that separates cooks from bakers: baking is a science, while cooking is an art. When baking, one little misstep can alter the texture, taste, and consistency of any recipe.
Hello ladies and gentlemen, PySec here coming at you with another informative(hopefully) article for you all. In the last tutorial, we finally finished our discussion about IP Addressing and I intentionally didn't mention a really important concept with which IP Addressing wouldn't be feasible without it. What I'm talking about is how our network device gets the IP Address in order to communicate with other devices on the network/Internet. There are many different ways for that to be accompli...
Hey everyone. Only found the site a few days ago but really loving it. Been
Welcome to the final tutorial of the series on standard C. This article will cover the linked list abstract data type (ADT). There will be a lot of abstraction to try to deliver the understanding in the most basic way for easiest interpretation of what they are and how they work, then we will get into the guts of it and learn the technical code underneath. For those who have yet to grasp the concept of pointers, it's advisable that you do that first before approaching this. Having learned thi...
Welcome to a tutorial on crypting technology. In this article, we will be discussing types of crypters, how they work and why they work. After defining these, we will then make our own basic crypter using the function I gave to you as a task to complete by yourself in the previous tutorial.
Considering that nearly half a million brand new apps were published to the Google Play Store in 2015, you can definitely call it a banner year for Android development. In fact, it's getting to the point where we're a bit spoiled as end users, since we've grown to expect something new and exciting practically every week.
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 published on the Google Play Store.
In case you didn't know, Android has an awesome hidden settings menu called "Developer options" that contains a lot of advanced and unique features. If you've ever come across this menu before, chances are you just dipped in for a minute so that you could enable USB debugging and use ADB features.
If you're one who enjoys a good DIY project, or if you're just tired of paying exorbitant labor fees to have your vehicle serviced every 5,000 miles, changing your own oil can be a rewarding endeavor. Even though cars and trucks are becoming increasingly over-engineered these days, manufacturers generally see to it that the basic maintenance items can still be taken care of in your driveway with a few common tools.
Checking the weather ranks among the most mundane but essential tasks you can do on your smartphone. Thankfully, both the iOS App Store and Google Play are loaded with weather apps that add some much needed spice to this daily routine, giving you less of a reason to be caught unaware.
So you finally decided to make the switch from iOS to Android, huh? Well first off: welcome to the world of tomorrow. And secondly: good call, mate.
These days, that pocket-sized computer we call a smartphone is home to your entire digital life. But with the onset of mobile payments and online banking, the line between your virtual world and the physical realm is becoming increasingly blurred.
It's been a while when the major web browsers first introduced HTTP Strict Transport Security, which made it more difficult to carry Man In The Middle (MITM) attacks (except IE, as always, which will support HSTS since Windows 10, surprised?).
You can find chili peppers in practically every cuisine. From the sweet Italian variety to the spicy Thai bird's chili and the smoky Mexican chipotle, peppers are ubiquitous and universally loved. But if you find the range and scope of these little fireballs overwhelming, you're not alone.
A few years ago I went hog-wild trying to achieve a zero-waste lifestyle. I didn't succeed, but the experiment taught me that we throw away things we could—and should—be using more.
Pumpkin carving and decorating is a favorite October pastime. After you've carved an amazing design or face into a pumpkin or two, you want to show it off through your window or set it out on your porch for the neighbors to see.
Heartbleed, move over. There's a new bug in town, and this time it's also affecting Mac and Linux computers. It's called Shellshock (its original official title is CVE-2014-6271), and it's currently got a 10 out of 10 severity rating over at the National Cyber Awareness System. While some updates have been issued to fix this bug, they were incomplete, and your system is probably still vulnerable, as it has been for the last probably 20 years.
Gatorade: its popular red flavor can stain the whitest fabric, and its sweet taste is oddly refreshing after breaking a sweat. If you've ever participated in a sport, you probably spent halftime at games and practice breaks chugging the stuff. Though it made its name as a sports drink, Gatorade is also a well-known hangover helper—but its beneficial and interesting uses don't end there. The brightly colored drink can do so much more than just hydrate you.
Each day, we read about another security breach somewhere in our digital world. It has become so commonplace that we hardly react anymore. Target, J.P. Morgan, iCloud, Home Depot, and the list goes on and on.
Eggs are incredibly important to cooks, and not just because they're tasty and a complete protein (many erratic genius/artist types make a point of eating an egg or two for breakfast). Yes, they are great when perfectly poached, scrambled, hard-boiled, and even scram-boiled, but they serve literally dozens of functions when used in recipes, especially baked goods.
Break out the office supplies and kitchen utensils, because improving your morning makeup routine is about to get a lot easier. Some of the things you have lying around the house can provide the perfect solution for some of the most common beauty problems. We've collected 10 of our favorites.
If you've read any health news in the past year or so, you've probably been bombarded with headlines announcing that frequent sitters face certain death, even when you're just relaxing and watching TV at home.
If you've been to a farmer's market during tomato season, chances are you know that heirloom tomatoes are pricier (and funnier-looking) than their hybrid counterparts.
When you know how to cook it, tofu is a delicious dish in and of itself—truly. Too many people have been subjected to poor quality or badly cooked tofu and told to eat it because it's a "healthy alternative" to meat. Usually what they bite into is a bland, rubbery mess coated with a random array of flavors.
It may sound irrational, but I bet a lot of you actually avoid doing any work at work—but not on purpose. You might be simply struggling with motivation, or you might just be overdosing on the caffeine. Whatever the issue, getting focused takes lots of time and effort.
UPDATE: The mod discussed below is no longer available for download. We are looking for an alternative and will update this page when we find one.
Hard-boiled (also known as hard-cooked) eggs are notoriously easy to mess up. We've all ended up with tough, rubbery egg whites and overcooked yolks that have that unappetizing gray-green ring around the edge. An ideal hard-cooked egg has a firm yet tender white, while the yolk is creamy and well-done without being mealy.
About ten years ago, Western research figured out that green tea was a nutritional powerhouse. After all, in Asian countries where green tea is consumed throughout the day, cancer rates tend to be much lower, although there are probably other factors contributing to that fact, like less processed food and red meat in the standard Asian diet.
There's a lot of cool features rumored to be included in next year's HTC One 2 (M8), the follow up to the flagship HTC One smartphone, including a fingerprint scanner, Android 4.4 KitKat, and Sense 6.0, but it's just too far away to get really excited about yet.
Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.
