How To: Recover WinRAR and Zip Passwords

How To: Make an Unbreakable Linux Password Using a SHA-2 Hash Algorithm

In Linux, all password hashes are normally stored using the MD5 hashing algorithm in the /etc/shadow file, but MD5 is algorithmically weak due to collision vulnerabilities. The new recommended standard are the higher level SHA-2 hashing algorithms, SHA256 or SHA512. As a friend pointed out to me, Ubuntu is currently the only distro implementing SHA-2 as the default. With SHA-2, your passwords take an unreasonably larger amount of time to calculate. This will greatly decrease how many password...

How To: Chain VPNs for Complete Anonymity

Big name individual hackers and hacker groups everywhere in the news are getting caught and thrown in jail. Everytime I see something like this happen, I won't lie, I get a little sad.

How To: Enable Code Syntax Highlighting for Python in the Nano Text Editor

With the plethora of programming that we promote at Null Byte, I figured a lot of you newbies that stop by IRC will need a big boost in the right direction to make your dive into programming a lot easier. A hot question that has been thrown around in IRC a lot when making the initial dive is, "How do I write code?". People who do not know much about computers can't understand how code is written. Code that we write here is usually scripted and written in Python, so we will use it as our examp...

How To: Hack Wireless Router Passwords & Networks Using Hydra

Leaving your wireless router at its default settings is a bad idea. The sad thing is, most people still do it. Once they've penetrated your network, hackers will change your router settings so they'll have an easy way back in. This allows them to change your network into a shell or proxy so they can forward their traffic anonymously through you when committing other dirty deeds.

News: Catch Creeps and Thieves in Action: Set Up a Motion-Activated Webcam DVR in Linux

When it comes to webcams these days, most people are using their laptops over desktops. The cameras are centered, integrated, and require no configuring. They're a cinch and usually have great resolution. So, then what do we do with all of those old wired desktop webcams that we've accrued over the years? Even if you still use an external USB one, chances are you're not using it daily, so why not come up with a better use for it?

How To: Run an FTP Server from Home with Linux

File Transfer Protocol, or FTP, is a network protocol made for transferring files in a client and host fashion over a Transmission Control Protocol (TCP) network, such as the internet. FTP is integrated into most browsers, and you have probably used it before. It is a common way to host files and transfer them easily. To access an FTP, a login is required, unless the server is configured to use anonymous logins (like the Arch Linux mirrors).

How To: Give Your GRand Unified Bootloader a Custom Theme

GRUB, or the GRand Unified Bootloader, is a program that installs to your Master Boot Record and controls what operating system you load at boot time. Normally, it is used for multi-boot systems. Multi-boots allow you to switch between operating systems installed on seperate drives, or partitions at boot time. Linux actually uses it as its default bootloader, even without multiple operating systems.

How To: Permanently Delete Files to Protect Privacy and Passwords

Permanently deleting files is something that a lot of people aren't aware of. Actually, most people think that once a file is deleted, it is gone forever. This is not the case. Hard drives write to the disk via magnetic charges, positive and negative correlate to 1s and 0s for binary. This is then interpreted into information for the computer to use and access.

How To: Get Free Wi-Fi from Hotels & More

Often times when staying at a hotel or anywhere for that matter, you'll whip out your laptop and check the local area for Wi-Fi. I know you've all been in my shoes when you find an unsecured network that appears to be public Wi-Fi belonging to the hotel or airport, and you connect to it. You connect fast and perfectly, only to find that when you open your browser, it says you don't have an account, and are filtered from accessing the web. This is because the owners of the network want to keep...
