Locking Down Linux: Using Ubuntu as Your Primary OS, Part 2 (Network Attack Defense)

After installing Ubuntu as your primary OS, you should have protected against USB Rubber Ducky payloads, defended against hard drive forensics, and reduced the overall attack surface against physical strikes. When defending against network-based attacks, you'll want to minimize hardware disclosures, prevent packet sniffers, harden firewall rules, and much more.

How To: Hide Apps on Your Samsung Galaxy's Home Screen, App Tray, and Search

You don't have to see every app installed on your phone if you don't want to. Samsung One UI makes it easy to hide apps from your Samsung Galaxy's home screen, app tray, and search tool, whether you want to declutter, simplify things, or keep other people from seeing some of the apps you use.

How To: Get One UI's Rounded Corners on Non-Samsung Devices

The two primary design paradigms in Samsung's One UI Android skin are vertical padding and rounded UI elements. The extra empty space at the top of most menus moves touchable elements closer to your thumb, and the rounded UI elements match the curved corners of modern smartphone screens. While you can't add the vertical padding on other Android phones, you can now get the rounded corners.

News: Apple's iOS 14 Developer Beta 6 for iPhone Contains Spatial Audio & Fixes for Files, Widgets, Automations, Mail & More

At first, Apple's six developer beta for iOS 14 isn't much to look at, but there wouldn't have been an update if there weren't some important issues to address. Most of the serious updates in build number 18A5357e revolve around SwiftUI, which even has a few new features, and there's a fix to Shortcuts automation that will likely please you if you use those.

How To: Switch from Grid to List View for Apps on Your iPhone's Home Screen in iOS 14

The average iPhone user has between 60 to 90 applications installed. On one of my devices, I have over 600. With a ton of apps to sort through, it can sometimes be challenging to find the one you're looking for without having to use the Search tool (which is even better in iOS 14). Even then, you may still come up dry.

How To: See if Your Phone Has A/B Partitions for Seamless Updates

If your phone has an A/B partition layout, there are two virtual hard drives that each contain a copy of Android. After every restart, it picks a partition to boot from, then the other lays idle. The idle partition can be overwritten with a new copy of the OS and it won't affect the active one. So the next time you reboot, it just switches partitions and it's as if you updated instantly.

How To: Change a Phone's Coordinates by Spoofing Wi-Fi Geolocation Hotspots

In many urban areas, GPS doesn't work well. Buildings reflect GPS signals on themselves to create a confusing mess for phones to sort out. As a result, most modern devices determine their location using a blend of techniques, including nearby Wi-Fi networks. By using SkyLift to create fake networks known to be in other areas, we can manipulate where a device thinks it is with an ESP8266 microcontroller.

How To: Android 10 Drastically Updated Location Permissions — Check Your Settings ASAP

With Android 10, there are now three options when an app asks to access your location: Allow, Deny, and Allow While In Use. That last one prevents apps from seeing your location unless you're actively using them, and it's the default now. But when you first update, most of your apps will still be allowed to access your location in the background — at least, until you do something about it.

How to Hack with Arduino: Building MacOS Payloads for Inserting a Wi-Fi Backdoor

Arduino is a language that's easy to learn and supported on many incredibly low-cost devices, two of which are the $2 Digispark and a $3 ESP8266-based board. We can program these devices in Arduino to hijack the Wi-Fi data connection of any unlocked macOS computer in seconds, and we can even have it send data from the target device to our low-cost evil access point.

How To: Get Started with MicroPython for ESP8266 Microcontrollers

For anyone interested in using cheap, Wi-Fi-connected microcontrollers like the ESP8266, the Arduino programming language can be a barrier to entry. Based on C++, Arduino requires knowledge of more computer science than languages like Python. Fortunately for beginners, setting up MicroPython on an ESP8266 allows anyone to write Python on affordable microcontrollers in a matter of minutes.

Android 10 Changelog: 60 New Features You Should Know About

|Choose Your View: Quick Bullet Points | Detailed Descriptions Android's newest major update is a special one — it's the tenth full version of the world's most commonly used operating system. The latest release, dubbed simply Android 10 (codename Android Q), was first showcased as a beta back in March 2019, so we've been digging around in it for several months. There's one dramatic visual change, plus there are a lot of goodies in general.

How To: Enable Dark Mode in Magisk

With Android 10 "Q" right around the corner, now would be a great time to get accustomed to the new system-wide dark mode it's bringing with it. Dark themes not only allow for more comfortable viewing at night, but can also consume less battery at the same time. With a single button tap, you'll be able to enable this new dark theme for all compatible apps without having to jump through hoops.

How To: Obtain Valuable Data from Images Using Exif Extractors

Metadata contained in images and other files can give away a lot more information than the average user might think. By tricking a target into sending a photo containing GPS coordinates and additional information, a hacker can learn where a mark lives or works simply by extracting the Exif data hidden inside the image file.
