How To: Protect Yourself from the KRACK Attacks WPA2 Wi-Fi Vulnerability

In October of 2017, Mathy Vanhoef released "Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2." This paper demonstrates a way to decrypt traffic on practically any WPA2 network, the most commonly used form of wireless security (seeing as all other forms of Wi-Fi encryption have already been broken). Practically all of the network-connected devices we use will need to be updated in some way in order to protect against this vulnerability, each of them in a different way.

How To: Sneak Past Web Filters and Proxy Blockers with Google Translate

Do you need proxy access, but cannot have it for some reason? The most common perpetrator behind the issue is the network you're trying to access the pages from.

How To: Run Windows from Inside Linux

Something that can shy a user away from making the switch to Linux is not having the option to go back to Windows. Luckily, there are solutions like dual-booting, where you can have both OS's installed right next to each other. However, Windows 8 appears as if it will block dual-boots with its neo-space BIOS that have been developed. Sneaky-sneaky. Windows users could still throw in a Linux live CD to try out Linux, but what does a Linux user do when they need something from Windows?

How To: Remotely Control Computers Over VNC Securely with SSH

VNC is a great protocol that you can use on Windows and Linux machines to remotely control computers. This is useful if you need to control your computer when away from home, help your grandma check her email, or help a client with a disk cleanup. VNC is secure in the sense that it requires authentication in order to make the connection, but after that, the data is sent over the internet unencrypted. This means that an attacker could sniff your traffic and snoop everything that's going on. Th...
