While you might suspect your MacOS computer has been infected with malware, it can be difficult to know for sure. One way to spot malicious programs is to look for suspicious behavior — like programs listening in on our keyboard input or launching themselves every time we boot. Thanks to free MacOS tools called ReiKey and KnockKnock, we can detect suspicious programs to discover keyloggers and other persistent malware lurking on our system.
One of the most common web application vulnerabilities is LFI, which allows unauthorized access to sensitive files on the server. Such a common weakness is often safeguarded against, and low-hanging fruit can be defended quite easily. But there are always creative ways to get around these defenses, and we'll be looking at two methods to beat the system and successfully pull off LFI.
When you can't think of a way to respond in Messenger with words, emojis and stickers will do the trick. Since Facebook is all about the "likes," which use a thumbs-up icon, there's a shortcut to the symbol just to the right of the chat field. It's always there to send a quick like in response to something. But it doesn't have to be the standard Facebook thumbs-up sign — it can be any emoji you want.
Say you're sending a snap to a friend at a restaurant, bar, store, what have you, but you're curious about the song that's playing in the background. You could leave the app to Shazam it, or you could ask screen-hogging Siri or Google Assistant what the track is, but why not just have Snapchat do the work for you? With its built-in scanner, you can discover a song without ever leaving the app.
Using Siri to perform tasks on your Google Home device was never possible until Apple released Siri Shortcuts in iOS 12. Actually, it wasn't possible until Google added support for Siri Shortcuts for Google Assistant in Nov. 2018. No matter the timing, the important thing here is that you can use Siri to command Google Assistant which, in turn, can command Google Home.
Directory traversal, or path traversal, is an HTTP attack which allows attackers to access restricted directories by using the ../ characters to backtrack into files or directories outside the root folder. If a web app is vulnerable to this, an attacker can potentially access restricted files that contain info about all registered users on the system, their permissions, and encrypted passwords.
Traditionally, if you were looking for end-to-end encrypted messaging, you'd stick with something like iMessage, WhatsApp, or Signal. However, if you already use Facebook Messenger, you have all you need for truly private chats with its built-in E2E encryption. It's available to all users, on Android and iOS — you just need to know where to look.
The week of the annual Consumer Electronics Show is supposed to be filled with good news for the augmented reality industry as AR headset and smartglasses makers show off their new wares.
Command injection is a technique used by hackers to execute system commands on a server, usually via a web application or some kind of GUI. This can happen when an application provides some sort of functionality to the user involving the use of system commands. When the input is not properly sanitized, commands not originally intended to be run are allowed to be executed.
If you're currently running macOS 10.11 or higher on your Mac and connect your iPhone to sync with iTunes, you may get an alert saying that "a software update is required to connect to your iPhone." Here's everything you need to know about what that means, how to update your system, and what to do if updating doesn't work.
Apple's own Photos app received some pretty amazing updates in iOS 11, but does iOS 12 have what it takes to one-up last year's Photos improvements? We think so.
It's no secret that you can protect notes on your iPhone with a password, but one thing that most people don't know is that you can actually set unique passwords for each note instead of a blanket password for all of them. It's not obvious at all in the Notes app, but it's easy to do once you've got the hang of it.
At Build 2017, the annual developer's conference, Microsoft featured a Windows Mixed Reality Academy. This class was designed to get a developer started creating Mixed Reality experiences quickly. For those of us already developing for the Microsoft HoloLens, while the class — which is now available on the Microsoft website — did offer our first real chance to work with the new Acer HMD, there was not much depth.
A 6,000-year-old forest inhabitant awakens to find life in the forest around it in crisis. Plants, trees, animals, and birds are moving north to escape increasingly heated air, even as mass extinctions take place around the world. The inhabitant stirs and remembers it has lived this before and knows what to do.
So while it is the weekend of San Diego Comic-Con, and it should not be a complete surprise — without a word of warning hitting my feed — the trailer for the upcoming film, Ready Player One was released today. And wow it looks amazing.
HIV-infected people who are treated long-term with antiviral drugs may have no detectable virus in their body, but scientists know there are pools of the virus hiding there, awaiting the chance to emerge and wreak havoc again. Since scientists discovered these latent pools, they have been trying to figure out if the remaining HIV is the cause of or caused by increased activation of the immune system.
It won't come as a surprise to hear that your cell phone, tablet, and laptop are loaded with bacteria and other organic material. While most of these bacteria are harmless, there are good reasons to reduce the capability of your mobile devices to infect you—or other people.
Six people have died from fungal infections in Pittsburgh hospitals since 2014—that fact is indisputable. The rest of the situation is much vaguer. A lawsuit has been filed against the hospitals on behalf of some of the deceased patients, alleging that moldy hospital linens are to blame. While the lawyers argue over who's at fault, let's look at how this could have happened.
What's in a sneeze? Quite a lot—dirt, mucus, and infectious germs—it seems. And sneezing the right way can reduce the germs you share with neighbors.
As researchers learn more and more about our intestinal bacteria—also called the gut microbiome—we're finding out that these microbes aren't just influencing our health and wellness, they're a useful tool for improving it, too.
Bacteriotherapy sounds a lot more amenable of a term than "fecal transplant," yet they're both treatments that use bacteria itself to cure or treat infections. Fecal transplants, specifically, are an up-and-coming treatment option for a potentially deadly and difficult-to-treat diarrheal infection called Clostridium difficile.
How do I get rid of these zits?! Whether its pimples, blackheads, or whiteheads, the name is the same, and the name is acne.
Even when no one is in your kitchen, it is crowded. The refrigerator, sink, and counters are all covered with microbes that are just hanging around. They are inadvertent remnants from the raw chicken you used in that recipe last night, brewing a bacterial cocktail in your Nespresso machine, or just growing their merry little colonies on your leftovers.
Now that we've talked about encryption and managing your passwords, let's continue this series on getting your Mac ready for hacking by turning our attention to the terminal.
Google has already issued a few updates to Android 7.0 Nougat. There aren't many headlining features, as these minor updates are mostly bug fixes and performance improvements. But there's a few security enhancements as well, so staying up-to-date with the latest patches is important for a number of reasons.
When Microsoft release an update to the HoloLens Development Edition at the end of May, there were a bunch of cool new features added in. Among them: New voice controls that make working in the HoloLens operating system much easier.
"It just ticked me off," he said. In March 2011, Neil Singh paid $50 to back the Hanfree iPad stand on Kickstarter. The project was funded at $35,000, but production stalled, and the delivery estimates kept getting pushed back.
I was on our new #nullbyte IRC channel when someone told me how tedious it is to install an OSX Virtual Machine on Virtual Box (I think it was wawa). We all know Linux rocks (gets acknowledgement from the crowd), but there are morons out there, multiplying at a never before seen rate, who use OSX. We at nullbyte should be prepared for anything and everything. So, in this guide I take you step by step to creating your OSX Yogemite VM.
Smartphones have become such a big part of our lives these days that they're now closely associated with our personal identities. No longer is it Ford versus Chevy, rock versus rap, or PC versus Mac—now, you're either an Android person or an iOS person.
I've never had a problem with veggies—we've always been the best of friends—but I do have a lot of other people in my life that have been less than enamored with this basic food group in the past. Some cite the bitter flavor associated with veggies like Brussels sprouts, while others dislike the various consistencies that come with boiling or steaming vegetables such as broccoli or eggplant.
What's up readers? Today I'll be introducing to you a new vulnerability called the Format String vulnerability (in case you missed the title). It won't be much, just a little motivation to keep you guys going. A little teaser, if you may.
Welcome to a tutorial explaining functions. This article will help clarify some things we have already been exposed to such as function prototypes, function calls, return values, etc.
In recent weeks, some people have been shunned from the Null Byte community because they expressed "black hat" aspirations. This is because Null Byte is the "white hat" hacker training/playground. Although most of us think we know what that means, it does beg the question; "Who and what is a white hat hacker?"
Smartphone cameras are so good nowadays that there's almost no reason to own a point and shoot. Once the megapixel spec race was finally settled (hint: more isn't always better), manufacturers started focusing on the quality of their camera sensors, which has led to a huge jump in color accuracy, dynamic range, and image clarity.
When there's a crappy stock app you want to hide, the easiest thing to do is just bury it in the back of a miscellaneous folder. But what if there's an app you want to hide on your home screen that you actually use? For instance, what if you don't want everybody in eyeshot to see what banks you use, or don't want anyone to know about your "dating" apps or porn shortcuts?
It's truly amazing how far smartphone camera hardware has come in such a short period of time. It took roughly 5 years to advance the image processing capabilities from a pixelated mess to the crisp and clear photos we can take today. This reaches well beyond the megapixel spec race, since camera modules these days sport vastly improved optics, wider aperture, and even larger pixel sensors that capture more light.
Google has finally released the next version of the world's leading operating system—Android 6.0 Marshmallow. This latest iteration isn't as much of a visual overhaul as Lollipop was, but it packs in more new functionality than almost any update before it. Awesome features like Now on Tap, granular permissions control, and a deep sleep battery-saving feature called Doze round out the highlights, but there is far more to it than that.
Your freezer is no one-trick pony. While it does excel at keeping your food fresh for as long as possible, it has a few secret talents it doesn't want you to know about. Like making soda slushies and pyro-friendly smoke mix, as well as reviving dead hard drives. Even better—it can help you do laundry.
No, your Apple Watch isn't totally hacker-proof, despite what some have claimed.
Welcome back, my future hackers! After my first tutorial about doxing, I decided I would dive a little bit deeper into the world of social engineering. In this tutorial we will learn some basic social engineering techniques to get into a company building, find out more information about the company's security, and maybe even exploit the company's computers if you get the chance.
