After the article on cracking a WEP key using a MAC, many users have requested similar *testing* of their security procedures using a popular LINUX distro and WinXP. This article delves into cracking a WEP key and a WEP key force using the most popular and user friendly LINUX distro out there : UBUNTU. All you need is a laptop with a wireless card and a copy of Ubuntu Linux. NOTE: Most of the Intel wireless adapters that come in built in most laptops these days should work.

Ubuntu (IPA pronunciation: /u’buntu/) is a Linux distribution offering an operating system predominantly targeted at desktop computers. Based on Debian GNU/Linux, Ubuntu concentrates on usability, freedom from restriction of use, regular releases, and ease of installation. Ubuntu is sponsored by Canonical Ltd., by South African Mark Shuttleworth; the name of the distribution comes from the African concept of ubuntu (roughly, “humanity towards others”).

First step, obviously, is to install Ubuntu. Just boot from the CD and follow the directions. If you have problems or need help installing UBUNTU, follow this guide straight from Ubuntu. Once you have the OS installed and configured/customized to your liking we can proceed with the first step. I’d suggest performing the following steps in order, otherwise you may have problems.

Next, install the extra repositories and all the programs that Ubuntu doesn’t preinstall. Make sure your machine is able to establish a connection to the Internet. If you can only connect via wireless and are having problems, there is a package called Wi-Fi radar that is helpful. To install the extra repositories, open a terminal window and type the following:

This article is a tutorial on how to trick Windows XP into giving you system priviledges. Using simple command line tools on a machine running Windows XP, we will obtain system level priviledges. The system run level is higher than administrator, and has full control of the operating system and it’s kernel. On many machines this can be exploited even with the guest account. This system account allows for several other things that aren’t normally possible (like resetting the administrator password).
The Local System account is used by the Windows OS to control various aspects of the system (kernel, services, etc); the account shows up as SYSTEM in the Task Manager process list, as seen in the following screen shot:
Local System differs from an Administrator account in that it has full control of the operating system, similar to root on a *nix machine. Most System processes are required by the operating system, and cannot be closed, even by an Administrator account; attempting to close them will result in a error message.

The following quote from Wikipedia explains this in a easy to understand way:
Quote: In Windows NT and later systems derived from it (Windows 2000, Windows XP, Windows Server 2003 and Windows Vista), there may or may not be a superuser. By default, there is a superuser named Administrator, although it is not an exact analogue of the Unix root superuser account. Administrator does not have all the privileges of root because some superuser privileges are assigned to the Local System account in Windows NT.

Under normal circumstances, a user cannot run code as System, only the operating system itself has this ability, but by using the command line, we will trick Windows into running our desktop as System, along with all applications that are started from within.   Procedure to get system level access and previlege escalation in windows I will now walk you through the process of obtaining SYSTEM privileges and a demonstration of this Windows XP admin exploit / super user hack 

This article contains information about how to modify the registry. Make sure to back up the registry before you modify it. Make sure that you know how to restore the registry if a problem occurs.If you use a “leaked” product key (a product key that is known to be available to the general public) for the deployment of Microsoft Windows XP across multiple computers (a Volume Licensing installation), you may not be able to install Windows XP or later versions of Windows XP or automatically obtain updates from the Windows Update Web site. Some common error messages you might have to deal with include” The product key used to install Windows in invalid”.
