Hacking Pranks: How to Flip Photos, Change Images & Inject Messages into Friends' Browsers on Your Wi-Fi Network

Networking is built largely on trust. Most devices do not verify that another device is what it identifies itself to be, so long as it functions as expected. In the case of a man-in-the-middle attack, we can abuse this trust by impersonating a wireless access point, allowing us to intercept and modify network data. This can be dangerous for private data, but also be fun for pranking your friends.

How To: Create a Strong (Or Stronger) Passcode for Your iPhone

When you first set up an iPhone, you'll be prompted to create a six-digit passcode to unlock your screen and access certain system settings. If you skip this step, you can always go back and create one, which we highly recommend. Without a passcode, everything on your iPhone is accessible by anyone who gets their hands on it — nosey friends, hackers, thieves, local law enforcement, the FBI — and you don't want that, do you?

PSA: Don't Update Your Pixel if You're Rooted or Have Custom Recovery Installed

How To: Use the Much-Improved Face Unlock Feature in Android Lollipop

I think it's safe to assume that most of us appreciate a little privacy and security when it comes to our mobile devices, which is exactly why we have lock screens that require unique passwords, patterns, or PINs.
