While there are many advantages to working from home, properly managing your time can be a real issue. Working remotely requires a particular skill set, including an ability to focus, self-motivate, and communicate from a distance. Thankfully, all of these skills are teachable.
Since its introduction in iOS 11, the Screen Recording tool has been a great way to show less tech-savvy users how to use their iPhones better. It's never been easier to show your grandmother how to disable Live Photos or lower screen brightness. However, banner notifications can appear during a recording, forcing you to start over. They can even interrupt a screen share during a Zoom or Skype meeting.
Hacking web applications can sometimes be challenging due to the sheer amount of moving parts they possess. At the core of these apps are HTTP requests and parameters, but these things are often concealed from the user, due to security reasons, convenience, or both. However, a tool called Arjun can be used to discover hidden HTTP parameters in web apps.
Anyone who has used Linux long enough is familiar with sudo. Short for superuser do (or substitute user do, depending on who you ask), it allows users to run commands as either root or another user on the system. From a hacker's point of view, sudo is often all that stands between them and root access. We'll be exploring an older vulnerability in sudo that allows a user to run commands as root.
If you've ever tried to update your Android phone manually, you know the process can be unnecessarily hard. There are so many steps and parts, that if one thing goes wrong, the whole process doesn't work. Recognizing this, the Android team came up with an even easier way.
One of the scariest things about the COVID-19 virus is that you can show no symptoms but still be infected (and contagious). Naturally, we all want to know whether we're carrying the new coronavirus, but if you're showing signs of COVID-19, how can you be tested to know for sure? Websites are popping up to help with that, screening for symptoms, and directing you to a testing site if needed.
Web applications are a prime target for hackers, but sometimes it's not just the web apps themselves that are vulnerable. Web management interfaces should be scrutinized just as hard as the apps they manage, especially when they contain some sort of upload functionality. By exploiting a vulnerability in Apache Tomcat, a hacker can upload a backdoor and get a shell.
While consumer-grade smartglasses are the holy grail for tech companies, smartglasses maker Vuzix knows where its bread is buttered, and that's in the enterprise segment.
The Pixel 4 is one of the most talked-about phones of 2019, and it has many things going for it, especially in the world of rooting and modding. Just as with previous Pixel generations, unlocking the bootloader is the gateway to realizing your device's true potential. It can make way for such things as TWRP, Magisk, custom ROMs, and many other device-specific mods just the same.
Apple unveiled the latest generation of its flagship earbuds, AirPods Pro, on Monday, Oct. 28. Aside from the increased price tag, new in-ear design, and wider charging case, the biggest change by far is in Active Noise Cancellation. Finally, we can listen to AirPods on a plane, walking by a busy road, anywhere with a lot of noise pollution. But how does it work?
If you have friends who aren't privacy-conscious, you've surely heard the old "What do I have to hide?" excuse. Despite the fact that billions of people are using the internet each day, many of them don't know the dangers that can find them. And many don't know the tools to combat them.
I've been using the Galaxy Note 10+ as my daily driver for a while now. I love it, but as with any phone, it loses its pizzazz after a while. But since it's an Android phone, there's always a way to add fresh features and functionality to the UI.
Drone mishaps, such as the collision that scratched a military helicopter in New York, are becoming something of an everyday hazard.
One of the first steps in attacking a web application is enumerating hidden directories and files. Doing so can often yield valuable information that makes it easier to execute a precise attack, leaving less room for errors and wasted time. There are many tools available to do this, but not all of them are created equally. Gobuster, a directory scanner written in Go, is definitely worth exploring.
Samsung has stepped up its camera game with the Galaxy S10's dual- and triple-lens systems. But as impressive as the hardware is, the native Samsung Camera app still isn't as good with image processing and video stabilization as the Google Camera app for Pixel phones. Thankfully, you can get the best of both worlds.
Popping a shell is often the main goal of a hacker, and it can be exciting when executed properly, but sometimes they do have their limitations. Metasploit's Meterpreter probably needs no introduction, but this powerful, dynamic payload can offer a leg up over normal shells. To prove it, we'll show how to take a normal command shell and elevate it to a Meterpreter session.
Dark mode support has steadily made its way to mainstream acceptance, with big-name apps like YouTube, Reddit, and Twitter adopting the feature to satisfy user demands. In this regard, Facebook is lagging, yet to offer the sought-after feature for easier viewing in low-light conditions. If your iPhone is jailbroken, however, you don't have to suffer like everyone else.
Things that are supposed to make life easier for developers and users are often easy targets for exploitation by hackers. Like many situations in the tech world, there is usually a trade-off between convenience and security. One such trade-off is found in a system known as Distributed Ruby, which can be compromised easily with Metasploit.
Nothing beats a human translator, but Google Translate and other software-based solutions have developed into decent alternatives for help with basic translations. Need an English word translated into German? No problem — but what if you need to have a conversation with someone who doesn't speak your language? Is Google Translate capable of doing that? The answer is not really.
It wouldn't be iPhone season without a new controversy. Chargegate, Apple's latest PR nightmare, is the name being used for charging issues on some iPhone XS and XS Max devices. If you plug in your iPhone at night — or whenever — then wake up or come back later and see that your iPhone has even less battery power, you're affected. But there is a fix you can implement right now.
Having an efficient workflow is an integral part of any craft, but it's especially important when it comes to probing apps for vulnerabilities. While Metasploit is considered the de facto standard when it comes to exploitation, it also contains modules for other activities, such as scanning. Case in point, WMAP, a web application scanner available for use from within the Metasploit framework.
Android does a great job at multitasking. Split-screen mode and picture-in-picture are terrific at letting you manage more than one app at a time. But there are some limitations. For instance, when you're playing a video and you open a second video in split-screen, the first one pauses. Thankfully, Samsung has a fix for this.
A simple security flaw can allow an attacker to gain a strong foothold with little effort on their part. When a web application permits remotely hosted files to be loaded without any validation, a whole can of worms is opened up, with consequences ranging from simple website defacement to full-on code execution. For this reason, RFI can be a promising path to obtaining a shell.
Apple released iOS 12 beta 9 to public beta testers on Monday, Aug. 27. The update comes at the same time as the release of dev beta 11. This is surprising, as Apple typically releases developer betas at least a few hours before the public version. Then again, everything Apple is doing with its iOS 12 beta as of late is surprising.
On August 1, Google Play started requiring new app submissions to target at least Android 8.0 Oreo's API. Then, as of November 1, all updates to existing apps were required target the same API. While at first glance, this change may mean little to you, it will have a profound impact on Android. Now, your favorite apps will be getting better.
