How To: Intercept Images from a Security Camera Using Wireshark

How To: Take Control of the Mouse & Keyboard in Python

While hackers adore the command line, working with the GUI (graphical user interface) of an operating system has some advantages. This is especially true when it comes to post-exploitation. When we can control the mouse and keyboard of a remote computer, we can truly say we have complete control over the device. Today, I'm going to introduce to you the PyAutoGUI module, which does just that, and just how much fun you can have with it!

Opinion: Gameloft Strikes Out with Asphalt Street Storm Racing

The Asphalt series has been a staple in the racing genre since its first incarnation all the way back in 2004 — I still remember buying it for my newly-obtained Nintendo DS. It warms my heart to see that, after all this time, Gameloft continues to produce mobile Asphalt games, releasing the latest for Android today.
