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.
Have you ever heard someone else's iPhone ringing and thought it was yours? Of course you did. iPhone ringtones are iconic, but not varied. If you're using one of the more popular iOS sounds, you'll likely encounter it in the wild multiple times. Why bother, when you can create your own custom ringtones right on your Mac.
On iPhones, the share sheet is a powerful yet largely underestimated tool. For the uninitiated, the share sheet is the menu that opens whenever you tap the share button (the box with the up-arrow). This menu features sharing options to first and third-party apps, as well as extra functions like saving, copying, duplicating, and more. Best of all? It's surprisingly customizable.
It's finally out. After months of testing, iOS 13 is available to install on your iPhone, which means over 200+ new features you can use right now. The update, released on Sept. 19, can be installed over the air or from a restore image using iTunes in macOS Mojave and older or Finder in macOS Catalina. Ditto for the 13.1 update issued on Sept. 24.
It is said that the best way to avoid detection when hacking is to leave no trace, and often that means not touching the filesystem at all. But realistically, in most cases, it's impossible not to interact with the filesystem in one way or another. The next best thing to do to throw off any investigators is to change the file attributes to hide activity. We can do this with Metasploit's Timestomp.
Picture this: You finally get that awesome angle, the perfect selfie. You can't wait to post it on your Instagram, except there's one problem — it looks a little flat and the colors just seem off. Maybe it's the lights? Or maybe your new smartphone camera isn't as good as you thought? How are your friends getting those beautiful photos they've been posting on social media?
When we reviewed the best file managers on Android, MiXplorer easily topped our list with its abundance of features, including tabbed browsing, support for up to 19 different cloud services, file and folder encryption, and much more. The only major complaint we had was the fact it couldn't be installed from the Play Store, but now, that is no longer the case.
It's not uncommon for hackers to attempt to move laterally between devices in proximity of a compromised device to maintain a prolonged presence in the network. Malware utilizing USB flash sticks to self-replicate and compromise air-gapped machines isn't a new concept.
In most macOS hacks, a non-root terminal is used to create a backdoor into the device. A lot of damage can be done as a low-privileged user, but it has its limitations. Think twice before granting a file permission to execute — an attacker might be able to convert your harmless scripts into persistent root backdoors.
Kali Linux is established as the go-to operating system for penetration testing, but in its default configuration, it's less than ideal for regular desktop use. While in many scenarios, a live boot or virtual environment can resolve these issues, in some situations, a full installation is better. A few simple changes can be made to a Kali Linux desktop to make it safer to use in this environment.
Talk about rapid-fire. Apple released the sixth beta for iOS 11.4 on Thursday, May 17. The update comes just three days after the release of iOS 11.4 beta 5, indicating that Apple is readily approaching the official release of the software. Apple has not issued an official iOS update since 11.3.1, which found its way to users over three weeks ago.
Apple is speeding things up in the iOS 11.4 development. The company released to developers the fifth beta for iOS 11.4 on Monday, May 15. Public beta testers got the update just hours later. The update comes just one week after the release of the fourth 11.4 beta, which introduced minor bug fixes and security patches to iPhone running the software. This beta version doesn't seem any different.
Apple released the fourth developer beta for iOS 11.4 on Monday, May 7, followed the next day with the public beta release. This update arrives just six days after the company seeded beta 3 to users, which fixed an 11.3 issue with 3D Touch, among other various bugs.
Apple released the third beta for iOS 11.4 on Tuesday, May 1. This update comes exactly two weeks after the release of the second beta, which, in addition to adding a new wallpaper, fixed issues with AirPlay, Music, and Keychain. The only noticeable change in beta 3 is a fix for unresponsive 3D Touch.
Deleted bank statements and private photos are still within an attacker's grasp, so don't think that emptying your recycling bin is enough to keep your files from coming back to life. It's possible for a hacker to recover compromising files and images from a backdoored computer completely without the victim's knowledge.
While installing the new Android 9.0 Developer Preview is fairly easy if you're using a Windows machine, it's a little trickier if you want to use macOS instead. To help you get the latest Android OS on your Google Pixel phone, we'll break down the whole process so using your Mac can be as simple as Windows.
The Galaxy S9 was announced February 25, and it's jam-packed with features like AR Emojis and and a Dual Aperture camera. You really love the cut of its jib, but maybe you don't have the means to get your hands on one. Well now, you can get the Galaxy S9's notification sounds and ringtones, to help you feel like you own one.
Android's share intents system is great in theory, but the execution can sometimes be frustrating. When you tap the "Share" button next to a link, app, or file, you see a list of apps you can share that item with. But it seems like every time you use this function, the list of apps is in a different order — especially when it comes to the Direct Share targets at the top.
Apple's codec for photos and videos in iOS 11, HEVC (High-Efficiency Video Coding), as well as the container, HEIF (High-Efficiency Image File Format), result in a reduction in size for pictures and movies without sacrificing quality. Seems like a win-win situation, but Windows-users can't open the .heic extension that these files use. In order to open HEIC files on a Microsoft Windows PC, you'll have to turn to third-party apps and tools. One of these tools, CopyTrans HEIC for Windows, essen...
File inclusion can allow an attacker to view files on a remote host they shouldn't be able to see, and it can even allow the attacker to run code on a target.
Any internet user will need to download files eventually, and most simply have faith that what they are downloading is trustworthy. This doesn't give much clarity into the contents of the file, but if the file's author published the original checksum, comparing it to the SHA-256 hash of the downloaded file can ensure nothing was tampered with.
Since the release of the T-Mobile G1, the Play Store has been flooded with apps that claim to improve performance by clearing cache and storage. These apps are typically useless, rarely providing more than a temporary fix which Android undoes immediately. As Android has continued to improve cache and storage management, such apps have become more trivial. However, there are few decent ones out there.
Scanning important paperwork on smartphones is a tedious process, often relying on either external scanners or third-party apps that had to be either purchased or were loaded with annoying ads just to get the job done. Thankfully, iOS 11 now lets you easily scan documents using your iPhone, and finally does away with the need for third-party apps or machines.
There are a ton of new features in iOS 11, but some of the best ones, in my opinion, are in the Camera app. They're not huge features, but they're much appreciated to anyone who's ever taken a Live Photo or portrait, or even to those who've needed to scan a QR code quickly.
One major iOS 11 improvement that Apple skimped out on during its WWDC presentation was the redesigned storage management system, which makes it easy to view storage consumption in greater detail on your iPhone — and even easier to free up storage space with surgical precision.
A new feature in Android Nougat lets you add your own custom tiles to the Quick Settings panel. This menu, which can be accessed by swiping down from the top of any screen, lets you quickly adjust settings and toggle system features on and off. So now that it's been opened up for third-party development, we're starting to see all sorts of cool and useful tiles roll in.
The LG V20 was released in the fourth quarter of 2016 as a flagship phone with audio capabilities far superior to that of anything else on the market—but only if you have your headphones connected. The single bottom-firing speaker, on the other hand, is just unpleasant to listen to. At first, it was believed there was a software issue with the speaker. However, it turned out to be an issue with the speaker grille impeding sound.
As the first phones to be made by Google, the new Pixel and Pixel XL have several slick customizations that you won't find on any other Android device. There's tons of functional stuff like the new Google Assistant and a much-improved camera app, but also a few aesthetic tweaks to help class up the joint.
Android Nougat came with a lot of new features, including a futuristic and sleek circle animation. When this article was originally published, it was rumored that the circular design would be used as the new boot animation in Android 7.0—but as it turns out, you'll only see this screen while you're installing a firmware upgrade or working with ADB.
When it comes to sharing files between a smartphone and a computer, there are several solutions available for a Windows and Android pairing. But for those of us with Apple devices, the selection of apps in this category isn't quite as great. You can use AirDrop to quickly share files, but searching for files is not so easy.
When you delete a file, Android doesn't actually remove it from your storage drive—instead, it simply marks that space as empty and pretends the file doesn't exist anymore. But deep down inside, the file that you originally wrote to that location is still physically there, at least until you randomly happen to save another file on top of that same spot.
Android's flexible operating system allows for lots of customization, and one of the most common ways to add personal flair to your smartphone is to set your own ringtones and notification sounds.
Whether scheduling meetings, events, tasks, or even keeping tabs on the weather, a good digital calendar can help you stay on top of your game in ways that a normal calendar could never do. Indeed, there are many calendars to choose from, but Google Calendar is one of the best due to Google's excellent cloud service, feature-rich web-client, and their easy-to-use Android and iOS applications.
If you're experiencing issues with an app or custom ROM and would like to report your problem to the developer, there's no better way to do it than by capturing a logcat. Android keeps track of all the commands that have been executed by various apps and services, which means that when something goes wrong, the error is clearly shown in this so-called logcat.
Welcome back, my aspiring hackers! In this series, we continue to examine digital forensics, both to develop your skills as a forensic investigator and to avoid the pitfalls of being tracked by a forensic investigator.
3D Touch is a new feature on the iPhone 6S and 6S Plus that's reinventing the way we interact with our smartphones. With just a little bit of added pressure when tapping on the display, you can perform Quick Actions from an app's home screen icon, "Peek" at emails, stories, and photos in-app, as well as perform other app-specific gestures. Since 3D Touch is such a new concept, here are some of the apps that currently support it, along with the shortcuts you can use.
While Windows 10's new File Explorer is just as, if not more, useful as it was in previous iterations of Windows, it could definitely still be better. Two features that would greatly improve File Explorer are tabbed results and a customizable user interface, similar to how they are in Google Chrome.
Welcome back, my hacker apprentices! A you know, Mr. Robot is my favorite TV show this year, and not just for the realistic hacking. Rami Malek, the actor who plays Elliot, is incomparable in his depiction of a young man with social anxiety who is alienated from a superficial, materialistic society and wants to make a better world. I believe we will see a lot more of this actor in coming years.
In modern versions of Windows, Microsoft made quite a few changes to Windows Explorer, the first of which is a new name—File Explorer. Another huge change that most will notice is that File Explorer now has a new look sporting the Ribbon interface.
If your Android device wasn't manufactured by Samsung, chances are it uses on-screen navigation buttons. Colloquially referred to as "Soft keys," these have become commonplace due to their flexibility, as well as the fact that manufacturers don't have to include extra hardware buttons with a propensity to fail.
