Download Kali Linux, from the creators of BackTrack

Great news for Hackers and Backtrack Linux fans! The most awaited penetration testing Linux distribution has been released called 'Kali Linux' or 'Backrack 6', from the creators of BackTrack itself. From last 7 years we have seen five awesome versions of Backtrack Linux. But this time to achieve some higher goals, team decided to leave the 4 years old development architecture and 'Kali Linux' born today.

Kali Linux is based upon Debian Linux, instead of Ubuntu and new streamlined repositories synchronize with the Debian repositories 4 times a day, constantly providing users with the latest package updates and security fixes available.

Another great feature introduced is that, because of Debian compliant system, it is now able to Bootstrap a Kali Installation/ISO directly from Kali repositories. This allow any user to easily build their own customization of Kali, as well as perform enterprise network installs from a local or remote repository.

The Kali Linux ARM Architecture images work like charm on Samsung ARM Chromebook, Raspberry Pi, ODROID U2 / X2 and SainSmart SS808.

With more than 300 penetration testing tools, completely free, Open source, Vast wireless device support, GPG signed packages and repos, Multi-language, Completely customizable make this distribution one of the best available masterpiece of  hacking community.

Once again, default root password is same “toor“, you can download Kali Linux here.

What is Kali Linux ?

Kali Linux is an advanced Penetration Testing and Security Auditing Linux distribution.

Kali Linux Features

Kali is a complete re-build of BackTrack Linux, adhering completely to Debian development standards. All-new infrastructure has been put in place, all tools were reviewed and packaged, and we use Git for our VCS.

• More than 300 penetration testing tools: After reviewing every tool that was included in BackTrack, we eliminated a great number of tools that either did not work or had other tools available that provided similar functionality.
• Free and always will be: Kali Linux, like its predecessor, is completely free and always will be. You will never, ever have to pay for Kali Linux.
• Open source Git tree: We are huge proponents of open source software and our development tree is available for all to see and all sources are available for those who wish to tweak and rebuild packages.
• FHS compliant: Kali has been developed to adhere to the Filesystem Hierarchy Standard, allowing all Linux users to easily locate binaries, support files, libraries, etc.
• Vast wireless device support: We have built Kali Linux to support as many wireless devices as we possibly can, allowing it to run properly on a wide variety of hardware and making it compatible with numerous USB and other wireless devices.
• Custom kernel patched for injection: As penetration testers, the development team often needs to do wireless assessments so our kernel has the latest injection patches included.
• Secure development environment: The Kali Linux team is made up of a small group of trusted individuals who can only commit packages and interact with the repositories while using multiple secure protocols.
• GPG signed packages and repos: All Kali packages are signed by each individual developer when they are built and committed and the repositories subsequently sign the packages as well.
• Multi-language: Although pentesting tools tend to be written in English, we have ensured that Kali has true multilingual support, allowing more users to operate in their native language and locate the tools they need for the job.
• Completely customizable: We completely understand that not everyone will agree with our design decisions so we have made it as easy as possible for our more adventurous users to customize Kali Linux to their liking, all the way down to the kernel.
• ARMEL and ARMHF support: Since ARM-based systems are becoming more and more prevalent and inexpensive, we knew that Kali’s ARM support would need to be as robust as we could manage, resulting in working installations for both ARMEL and ARMHF systems. Kali Linux has ARM repositories integrated with the mainline distribution so tools for ARM will be updated in conjunction with the rest of the distribution. Kali is currently available for the following ARM devices:
• rk3306 mk/ss808
• Raspberry Pi
• ODROID U2/X2
• Samsung Chromebook

Kali is specifically tailored to penetration testing and therefore, all documentation on this site assumes prior knowledge of the Linux operating system.

OS X

Hardware and software made for each other.

Since the software built into every Mac is created by the same company that makes the Mac, you get a fully integrated system in which everything works together perfectly. OS X works with the processor in your Mac to deliver the best possible performance. It works with the Multi-Touch trackpad in Mac notebooks so they feel natural to use. Power Nap takes advantage of the Mac hardware to keep the entire system up to date while it sleeps.¹ And OS X gives you long battery life by working with the computer’s built-in sensors to dim the screen in low-light conditions and even regulating processor activity between keystrokes.

Multi-Touch, Mac style.

Use your fingers to tap, scroll, pinch, and swipe your way around the Mac. Because Apple makes both the hardware and software, Multi-Touch gestures are remarkably precise. This precision makes Multi-Touch the most natural and intuitive way to use a computer. When you scroll down on your trackpad or Magic Mouse, your document scrolls down. When you scroll up, your web page scrolls up. When you swipe left, your photos move left. These and many more gestures make all you do on your Mac easier, intuitive, and fun. Learn more about Multi-Touch gestures.

Microsoft Windows

Microsoft Windows

Microsoft Windows 7 Desktop

Microsoft Windows is a family of proprietary operating systems designed by Microsoft Corporation and primarily targeted to Intel architecture based computers, with an estimated 88.9 percent total usage share on Web connected computers. The newest version is Windows 7 for workstations and Windows Server 2008 R2 for servers. Windows 7 recently overtook Windows XP as most used OS.
Microsoft Windows originated in 1985 as an operating environment running on top of MS-DOS, which was the standard operating system shipped on most Intel architecture personal computers at the time. In 1995, Windows 95 was released which only used MS-DOS as a bootstrap. For backwards compatibility, Win9x could run real-mode MS-DOS and 16 bits Windows 3.x drivers. Windows Me, released in 2000, was the last version in the Win9x family. Later versions have all been based on the Windows NT kernel. Current versions of Windows run on IA-32 and x86-64 microprocessors, although Windows 8 will support ARM architecture. In the past, Windows NT supported non-Intel architectures.
Server editions of Windows are widely used. In recent years, Microsoft has expended significant capital in an effort to promote the use of Windows as a server operating system. However, Windows' usage on servers is not as widespread as on personal computers, as Windows competes against Linux and BSD for server market share.

About Ubuntu The Ubuntu story

ubuntu |oǒ'boǒntoō|

Ubuntu is an ancient African word meaning 'humanity to others'. It also means 'I am what I am because of who we all are'. The Ubuntu operating system brings the spirit of Ubuntu to the world of computers.

Where did it all begin?

Linux was already established as an enterprise server platform in 2004. But free software was still not a part of everyday life for most computer users. That's why Mark Shuttleworth gathered a small team of developers from one of the most established Linux projects – Debian - and set out to create an easy-to-use Linux desktop, Ubuntu.
The vision for Ubuntu is part social and part economic: free software, available free of charge to everybody on the same terms, and funded through a portfolio of services provided by Canonical.

Ubuntu releases

The Ubuntu team broke new ground in committing to a programme of scheduled releases on a predictable six-month basis. It was decided that every fourth release, issued on a two-year basis, would receive long-term support (LTS). LTS releases are typically used for large-scale deployments.
Ubuntu is different from the commercial Linux offerings that preceded it because it doesn't divide its efforts between a high-quality commercial version and a free, 'community' version. The commercial and community teams collaborate to produce a single, high-quality release, which receives ongoing maintenance for a defined period. Both the release and ongoing updates are freely available to all users.

Governance

Version 4.10, codenamed the 'Warty Warthog', the first official Ubuntu release, was launched in October 2004. Global interest in Ubuntu was dramatic from the outset. The year following the Warty Warthog release saw huge growth in the Ubuntu community as thousands of free software enthusiasts and experts joined.
The governance of Ubuntu is somewhat independent of Canonical, with volunteer leaders from around the world taking responsibility for many of the critical elements of the project. It remains a key tenet of the Ubuntu Project that Ubuntu is a shared work between Canonical, other companies, and the thousands of volunteers who bring their expertise to bear on making it a world-class platform for the whole world to use.

Ubuntu today

The first version of Ubuntu was based on the GNOME desktop. We have since added a KDE edition, Kubuntu, and a server edition. All of the editions of Ubuntu share common infrastructure and software, making Ubuntu a unique platform that scales from consumer electronics to the desktop, and into the cloud for enterprise computing. Developers can work on their desktop of choice, and smoothly deliver code to cloud servers running the stripped-down Ubuntu Server Edition.
In recent years, special emphasis has been placed on netbooks for lightweight, connected, mobile computing, and on the cloud as a new architecture for data centres. Ubuntu is a pioneer in both fields, with Ubuntu Netbook Edition and Ubuntu Enterprise Cloud setting the standard for easy deployment and management. Ubuntu is hugely popular on Amazon's EC2 and Rackspace's Cloud, and is pre-installed on computers from Dell, Lenovo and other global vendors.
Ubuntu still is and always will be free to use, share and develop. We hope it will bring a touch of light to your computing – and we hope that you'll join us in helping to build the next version too.
