In 2013, Offensive Security released Kali Linux, a rebuild of BackTrack Linux derived from Debian. Since then, Kali has gone on to become somewhat of a standard for penetration testing. It comes preconfigured with a collection of tools accessible by a menu system, tied togethe ...more

Anyone who has rooted their Android device has likely used a tool called Android Debug Bridge, better known as ADB, at some point during the process. For most, that is their only interaction with the ADB, but to be a true Android power user, you need to really know the tools a ...more

For a moment, picture a situation where you want to host some files or images, but you do not want it traced back to you. Perhaps you're working on a project with others and need secure data storage. Anonymity is the new shield of the 21st century—and you best protect yourself ...more

Overclocking is quite an awesome thing. When computer components are designed, they are made to run at a certain speed, otherwise known as their clock and bus speeds. These limits are not actually limits. You can overclock components, which essentially makes them go faster tha ...more

Making your own circuit boards can be a daunting challenge. You have to design a schematic, test it on a breadboard, design the board layout, and then after all of that, you still have to print and etch a board! Luckily, we have Fritzing. Fritzing is a free open-source PCB d ...more

It's common for IoT devices like Wi-Fi security cameras to host a website for controlling or configuring the camera that uses HTTP instead of the more secure HTTPS. This means anyone with the network password can see traffic to and from the camera, allowing a hacker to interce ...more
