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.

This can be dangerous for private data, but also be fun for pranking your friends.

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.

Not only are there separate installers for each Android version, but now, you also need to know exactly what type of processor is in your device to make sure you're downloading the right files. In fact, CPU architecture is becoming a factor in more and more scenarios these days, including certain sideloaded app updates and, of course, custom ROMs.

How To: Root the Nexus 6P or Nexus 5X on Windows, Mac, or Linux—The Foolproof Guide

This year, Google released two Nexus phones to glowing reviews, and as we've grown to expect, the Android community wasted no time in coming up with a root method for both. In fact, legendary root developer Chainfire even devised an entirely new "systemless" method for rooting that should make updating a bit less complicated, along with a few other benefits.
