How To: Add Your Own Custom Screensaver Images to Your Kindle Lock Screen

Don't be too disappointed if you don't have the spiffy new Kindle Touch, there is an up side. The benefit to owning the older (duller) models is that the firmware remains the same throughought generations, so the hacks retain their usefulness. This has given the modding community for Kindle a bunch of time to flourish, with tons of great code, hacks and homebrew. Today's Null Byte is going to show you how you can root, and then remove the crappy original screensavers that come installed on th...

How To: Get Netflix Beta on Android — Even When the Beta Program Is Full

Netflix has offered its beta program officially through the Play Store for some time now. Still, the issue most of us face — the beta availability is always scarce. Without getting lucky and landing a beta spot early on when the gates were open, there wasn't much you could do about it. However, there's now a brand new method you can use to sideload the Netflix beta app and join in on the fun.

How To: Hide All Traces of Your Apps & Pictures on Android

Unlike some of the popular app lockers out there, a nifty app fittingly named App Hider completely erases apps, files, and their associated footprints from your smartphone.

How To: The Best External Storage Options for iPhone That Work with iOS 13's Files App

The Files app received a big update in iOS 13. Before, it was limited to local and cloud-based files, but now you can access data from external storage devices, including SD cards and USB drives. But before you try to connect your favorite card or drive to your iPhone, there are a few things you need to know.

How To: Password-Protect Your Pages Documents So Only You & Allowed Collaborators Can Access Them

Your writing is just that — yours — so the work you do in Apple Pages should remain private until you choose to share it. Apple seems to share this sentiment. As another symbol of its dedication to user privacy and security, the company includes a feature in its word-processing app for iOS that allows you to lock documents behind a password, as well as with Face ID or Touch ID.

How To: Root Your Pixel 3 on Android 10

When new Android versions come out, the modding community has to find new ways to root the OS. It's a fun cat and mouse game to follow, but it also means the process of rooting isn't exactly the same as it was the last time you did it. Android 10 changes how root works on a system level for some devices, but luckily, the developers are already on top of things.

Android for Hackers: How to Backdoor Windows 10 & Livestream the Desktop (Without RDP)

The Windows 10 desktop and microphone can be livestreamed without using Remote Desktop Protocol (RDP) software and without opening any ports on the target computer. A hacker with low user privileges can monitor and exfiltrate a target's every move and private conversation in real time no matter where they are. Hackers are watching and listening, and there are few ways to protect yourself.

How To: Apply OTA Updates on Your Rooted Pixel 2 or 2 XL

So, you rooted your Pixel 2 or 2 XL and everything seems to be working quite well. However, a month passes, and you get a notification to install the monthly security update. Like clockwork, Google has been pushing out OTA security patches every single month for a while, but there is a new problem for you at this point — as a rooted user, you are unable to apply the update correctly.

How To: Perform Local Privilege Escalation Using a Linux Kernel Exploit

Getting root is considered the Holy Grail in the world of Linux exploitation. Much like SYSTEM on Windows, the root account provides full administrative access to the operating system. Sometimes even a successful exploit will only give a low-level shell; In that case, a technique called privilege escalation can be used to gain access to more powerful accounts and completely own the system.

How To: Securely Sync Files Between Two Machines Using Syncthing

Transferring hundreds of screenshots, webcam recordings, keystroke logs, and audio recordings between your VPS and a local Kali machine can be tricky. Services like Dropbox don't always have the best privacy policies and suffer data breaches just like any other website. To mitigate these risks, we'll use a secure, open source, and decentralized alternative.

How To: Use Beginner Python to Build a Brute-Force Tool for SHA-1 Hashes

Developers creating login systems know better than to store passwords in plain text, usually storing hashes of a password to prevent storing the credentials in a way a hacker could steal. Due to the way hashes work, not all are created equal. Some are more vulnerable than others, and a little Python could be used to brute-force any weak hashes to get the passwords they were created from.

How To: Extract & Back Up All of Your Text Messages on Android

It always helps to be prepared for the worst. This applies to our phones now more than ever, as we depend on them to be our record keepers for text messages from friends, family, and coworkers. If you ever lose or severely damage your phone, having a backup of your precious texts gives you the peace of mind of knowing that you can always get them back.

How To: Hack Forum Accounts with Password-Stealing Pictures

The pictures we upload online are something we tend to think of as self-expression, but these very images can carry code to steal our passwords and data. Profile pictures, avatars, and image galleries are used all over the internet. While all images carry digital picture data — and many also carry metadata regarding camera or photo edits — it's far less expected that an image might actually be hiding malicious code.

How To: Drag & Drop on Your iPhone

Apple first added a "Drag and Drop" feature to iPads in iOS 11, but your iPhone can do a little of the magic, too. It's just not so obvious. While you can't drag and drop items from one app to another like you can on an iPad using Split View and Slide Over, you can move things around in certain stock applications. And it works the same whether you're using iOS 11, 12, or 13.

How To: Get Apple's Live Fish Wallpapers Back on Your iPhone

Remember the live fish wallpapers from iOS 9? They may be a fading memory at this point since Apple removed them all from the iPhone in iOS 11, but there is a way to get those fishies animated on your device again. They'll be live photos for your lock screen, which is as good as it will get until Apple lets us use all its live wallpapers, new and old, one day, which will probably never happen.

News: Google Just Made It Easier to Flash Images & Sideload Updates on Your Android Device

Anyone who's ever flashed factory images to manually update an Android phone knows how tedious the process can be. Unlocking the bootloader and flashing Android firmware requires the use of ADB and Fastboot—but, like getting a whole pizza pie when all you wanted was a slice, users in the past had to download the entire Android Studio development package or SDK in order to get the two utilities.
