Thanks to its intuitive interface that makes sending and receiving money a breeze, Venmo has become the go-to app for millions in the US. In fact, you've probably heard the term "Venmo you" being tossed around between friends. But before you take the plunge and sign up, it's always a good idea to read the fine print and know what you're getting into. Money is involved, after all.
JavaScript is one of the most common languages used on the web. It can automate and animate website components, manage website content, and carry out many other useful functions from within a webpage. The scripting language also has many functions which can be used for malicious purposes, including stealing a user's cookies containing passwords and other information.
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?).
Sometimes you come across problems and glitches when you're playing FarmVille, FrontierVille, any of your facebook games, or even just using the internet for ordinary purposes! It might just be getting really slow, or you might start losing data or in-game items. As the Zynga customer support article will tell you, you sometimes need to clear you browser and flash cache! Here are some simple steps to do just that!

In this motorcycle maintenance video series, learn how to change a tire on your bike. Our expert mechanic will walk you through the process, with tips on what tools to use, how to remove the carter pin and axle nut, how to loosen chain bolts and punch the axle, types of tires to choose from, how to replace the tire and properly alig...
Using either iMessages or FaceTime on the iPhone is a great alternative for coworkers to stay in touch in the event that messaging services like Slack go down. They're also a handy means of communicating between buyers and sellers, as it provides a more intimate way of either checking out or showcasing a product. But you're not always going to want to give out your real number to everyone.
Amazon just unveiled the Kindle Oasis, the latest model in its popular line of e-readers. There are a couple of nice new features, but it's pretty hard to see how any of them justify the whopping $290 price tag (or $310 if you don't want ads littering your screen).
Hi everyone! Last time we finished analyzing the assembly representation of our vulnerable piece of code (have I ever told you it is vulnerable?). This time we are going to introduce some fundaments about exploitation by demonstrating how to crash a program's execution. If that sounds lame, next time we will see how this crash can in fact be useful to control the program's execution, achieving remote code execution!
Whether you're a celebrity or someone with something to hide, Facebook allows you to keep your "friends list" private so you can protect the identities of your Facebook friends. But it only kind of protects them.
The transcribing app can be an invaluable tool, especially if you're a student or are in a profession that relies on audio journals or interviews. These apps can convert important recordings like lectures and meetings into text for you to carefully read through to better comprehend.
There are loads of reasons for somebody to want to recover a Windows password, and there are lots of different ways of doing it. My favorite of all of these ways is to use a piece of software called Ophcrack because:
The iOS 14.4 developer beta was pushed out a day ago, and now the iOS 14.4 public beta is out and ready for your iPhone. At first glance, there's not much to look at in the new beta release, and it's not yet known if it lays out the groundwork for missing features such as 5G data with dual SIMs, shared third-party app subscriptions, and Xbox Core Controller.
The next big phase of iOS 14 has started with the release of the iOS 14.4 beta. Right now, the developer-only beta features only one known item. Apple introduced the ability to scan App Clip Codes in iOS 14.3 with the Code Scanner control, and now in iOS 14.4, you can launch a local App Clip experience via Camera, NFC, Safari Smart App Banner, or iMessage.
PayPal is one of the most popular payment systems across the globe. It makes payments fast, easy, and secure, and with 250+ million users, it's not going anywhere. If you're new to the online service, one of the first things you should learn is how to add your bank account, credit card, or debit card to PayPal, and make your life easier when it comes to online payments and withdrawals.
Our universe has never been closer thanks to Apple's ARKit. YouTube user Jenil Kansara has been playing around with ARKit features and created a solar system in his room.
Devastating and deadly, land mines are a persistent threat in many areas of the world. Funding to clear regions of land mines has been decreasing, but new research may offer a less dangerous method of locating hidden, underground explosives by using glowing bacteria.
Once you've designed some holograms with HoloLens, you'll need to get them to interact with the environment. That's where Spatial Mapping comes in. There are five basic purposes for using HoloLens's Spatial Mapping with your app:
Welcome back, my greenhorn hackers! The Holy Grail of any hacker is to develop a zero-day exploit—an exploit that has never been seen by antivirus (AV) and other software developers, as well as intrusion detection system (IDS) developers. In that way, you can exploit systems with your newly discovered vulnerability with impunity!
Newer gaming systems like the PlayStation 4 have a nice, subtle feature that goes a long way towards helping create a more immersive experience. Any time you're on the main menu or home screen, an ambient background music track is playing, which adds an aural appeal to an experience that would otherwise be all about the visuals.
Welcome back, my hackers apprentices! To own a network and retrieve the key data, we only need to find ONE weak link in the network. It makes little sense to beat our heads against heavily fortified systems like the file and database server when we can take advantage of the biggest weak link of all—humans.
Fluorescein is a commonly used fluorescent dye that is quite hard to come by in a concentrated form. Fortunately, it's used in relatively large quantities in highlighter markers and can be extracted by a fairly simple process. Fluorescein makes spectacular explosions of color as it dissolves into water and can be used for many different purposes that are addressed in the video below.
In this video, I'll be demonstrating how anyone can make their own iodine clock reaction with simple over-the-counter chemicals.
Welcome back, my hacker apprentices! In recent weeks, the revelation that the NSA has been spying on all of us has many people up in arms. I guess I take it all in stride as I just assume that the NSA is spying on all of us—all of the time. Don't get me wrong, I don't condone it, but I know the NSA.
There's a lot that goes into making a nice crystal radio set, so this is going to have to be broken down into two parts. The first part is the actual making of a functional radio, and the second part is making the whole arrangement look nice. In this part, I'm actually going to tell you more than just how to make a crystal radio, but I'm also going to explain how and why they work. Crystal radios are pretty Steampunk in and of themselves, since they were first developed in the late 19th centu...
This is a cool little trap that me and some friends came up with while messing around with TNT and redstone on a big platform in the sky. The reason we called it the 'Roof Lever Trap' is because it utilizes the ability to place levers on the bottom side of blocks, which was introduced in Minecraft 1.3.1.
This is a refreshing spring update on your classic hamburger slider. Instead of using a ground beef patty, I am using shrimp tempura. This recipe calls for fresh truffles, but fresh truffles are hard to come by so feel free to use truffle oil (it is much more affordable and what I usually like to use). The flavor will be just as good.
The best chemistry experiments are those you can perform with items already laying around your house. With only some sugar, salt substitute and an instant cold pack, you can make your very own gunpowder! Being able to make homemade gunpowder without a trip to the store can be a lifesaver, no matter if it's just for testing out a Civil War-era musket, blowing up stubborn tree stumps, or preparing for battle when imperialists overrun your country.
A convincing domain name is critical to the success of any phishing attack. With a single Python script, it's possible to find hundreds of available phishing domains and even identify phishing websites deployed by other hackers for purposes such as stealing user credentials.
A remote administration tool, or RAT, is a piece of software used for remotely controlling machines. They are commonly used by tech support to gain remote access for troubleshooting purposes, but RATs are also an important part of a hacker's advanced persistent threat (APT) toolkit. Unlike standard administration RATs, these tools are designed to be delivered stealthily and operate undetected.
Welcome back, my greenhorn hackers! As all you know by now, I'm loving this new show, Mr. Robot. Among the many things going for this innovative and captivating program is the realism of the hacking. I am using this series titled "The Hacks of Mr. Robot" to demonstrate the hacks that are used on this program.
Apple is widely known for keeping a tight grip on iOS, disallowing open-source and third-party downloads. While there are many reasons for this, the three most frequently referenced are quality control, malware prevention, and of course—money.
Apple no longer has an exclusive province to LiDAR for the purposes of augmented reality. This week, headset maker Varjo unveiled its new VR-3 and XR-3 headsets, the latter of which includes LiDAR sensors and stereo RGB cameras to enable depth sensing and inside-out tracking of real-world environments for "pass-through" mixed reality experiences.
We've all seen the login pages that allow you to log in to third-party accounts using your credentials from Facebook, Google, or Twitter. It saves you the trouble of creating another account and remembering more passwords — but it can also become a privacy and security issue, which is why Apple created the "Sign in with Apple" feature for iOS 13.
You may have recently seen a plethora of Instagram users, including celebrities and politicians, sharing a screenshot declaring that the platform will implement a new "rule" where it would own and could use your photos and videos however it wishes. The screenshots are part of an internet hoax, one that's been around in one way or another since 2012, but what can Instagram actually do with your media?
Don't look now, but stock photo mega-site Shutterstock may have the most extensive library of augmented reality content available.
