How To: Burn an XDG3 Formatted Xbox 360 Game ISO with Windows

This is the Windows OS counterpart to my tutorial on how to burn the new XDG3 formatted games on Xbox 360. Microsoft invented a new disc format system to trump piracy, it's called XDG3. XDG3's standard is to burn a whole extra gigabyte of data to the disc, to allow more content, but more importantly for stopping piracy. This extra gigabyte of data makes it impossible to burn or rip a game the traditional way. So how on earth can we burn our fully-legal back-ups that we should rightfully be ab...

How To: Reveal Saved Browser Passwords with JavaScript Injections

JavaScript is the language of the internet. It is what allows us to create dynamic, interesting webpages that are fast, web-based applications and so much more. The primary use of JavaScript is to write functions that are embedded in or included from HTML pages and that interact with the Document Object Model (DOM) of the page. This is the magic that allows all of what we see to happen, and for our browser to be manipulated.

How To: Recover Deleted Files in Linux

File recovery on Linux is a bit different than Windows. It requires different software than the Windows counterparts because every OS has their own file system. Windows uses NTFS, or FAT file systems, while on the other hand, Linux uses ext-based file systems. I personally use ext4 file system because it's the latest and greatest ext-journaling system and supports a large level of directory recursion and file sizes, but most installations still use ext2 or ext3. When files are deleted from a ...

How To: Recover Deleted Files in Windows

Everyone has deleted a file or folder on accident before. Sometimes people even delete stuff on purpose, only to find out that they needed the files after all. If you're experiencing one of these mishaps, don't worry, file recovery is possible in most cases!

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: 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: 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.

How To: How Cross-Site Scripting (XSS) Attacks Sneak into Unprotected Websites (Plus: How to Block Them)

XSS stands for cross-site scripting, which is a form of web-based exploitation that uses client-side vulnerabilities in a web page to execute malicious JavaScript codes. JavaScript is referred to as "cross-site" because it usually involves an external website containing the malicious code. That code is most commonly used to steal cookies with a website that the attacker created and hosted on another server. The cookies can then be used to escalate privileges and gain root access to someone's ...

How To: Stream Media to a PS3 or Xbox 360 from Mac & Linux Computers

One of the main reasons I was held back from fully switching over to Linux was the fact that media streaming is nearly impossible. You have two choices in Windows: either you use file sharing with Windows Media Player, or you can just use the Windows Media Center. But both of these softwares are not for Linux or Mac. Microsoft doesn't like to make open source software because they believe in making a profit, instead of allowing others to innovate it.

How To: Share Your Laptop's Wireless Internet with Ethernet Devices

Sharing a laptop's wireless Internet connection with other computers connected to its Ethernet port is a great skill to know. It can be good for a number of reasons; Your computer may not have proper hardware to have a standard setup, or you may have an awkward network topology where sharing your wireless Internet via Ethernet would just be a better option.

How To: Carve Saved Passwords Using Cain

I've previously mentioned how saving browser passwords is a bad idea, but I never went into much detail as to why. Passwords that are saved in your browser can be carved out and stolen very easily. In fact, even passwords you save for instant messaging and Wi-Fi are vulnerable. Windows is very inefficient with the way it stores passwords—it doesn't store them in key-vaults, nor does it encrypt them. You're left with passwords residing in memory and filespace that's unencrypted.

How To: Mine Bitcoin and Make Money

Bitcoin is a new currency built off "Satoshi Nakamoto's" (alias) 2008 Bitcoin white-paper. Bitcoin provides its users with a way to make peer-to-peer (P2P) transactions without having to use a bank as a mediator. There is no middle man, no corporation backing it, and no one has access to your money, except you. It's decentralized from government, run by the people, for the people.

How To: Create an SSH Tunnel Server and Client in Linux

SSH is what is referred to as the Secure SHell protocol. SSH allows you to do a plethora of great things over a network, all while being heavily encrypted. You can make a remote accessible shell on your home computer that gives you access to all your files at home, and you can even tunnel all of your traffic to keep you anonymous and protected on public Wi-Fi. It has many great uses and is a must have tool for your arsenal. It was designed to replace the insecure Telnet protocol, which sends ...

How To: Use Cygwin to Run Linux Apps on Windows

You'll see a lot of Linux action going down here at Null Byte. We use Linux for hacking-related stuff because it provides a more relaxed programming environment, making it easy to write exploits and tools. Linux has many features Windows is lacking, such as full control over the OS right down to the Kernel and massive availability of mature, open source (read: free & tweakable) tools & projects.

How To: Bypass Windows and Linux Passwords

If you're interested in bypassing Windows and Linux passwords, there is a great tool from the good people at Kryptoslogic. Have you ever forgotten your administrator password? Have you ever bought a used computer with a password on it? Well, Kryptoslogic have created a boot-disc call 'Kon-Boot', which allows you to bypass any Windows 32 or 64 bit OS, as well as Linux passwords. There is both a paid and freeware version available.
