Kali Linux[3] is a Debian-derived Linux distribution designed for digital forensics and penetration testing.[4][5][6][7] It is maintained and funded by Offensive Security Ltd. It was developed by Mati Aharoni and Devon Kearns of Offensive Security through the rewrite of BackTrack, their previous information security testing Linux distribution based on Knoppix. The third core developer, Raphaël Hertzog, joined them as a Debian expert.[8][9][10][11][12]

Development[edit]
Kali Linux has over 600[13] preinstalled penetration-testing programs, including Armitage (a graphical cyber attack management tool), Nmap (a port scanner), Wireshark (a packet analyzer), John the Ripperpassword cracker, Aircrack-ng (a software suite for penetration-testing wireless LANs), Burp suite and OWASP ZAPweb application security scanners.[14][15] Kali Linux can run natively when installed on a computer's hard disk, can be booted from a live CD or live USB, or it can run within a virtual machine. It is a supported platform of the Metasploit Project's Metasploit Framework, a tool for developing and executing security exploits.[14]

Kali Linux is based on Debian Testing. Most packages Kali uses are imported from the Debian repositories.[18]
The Kali Linux project began quietly in 2012, when Offensive Security decided that they wanted to replace their venerable BackTrack Linux project, which was manually maintained, with something that could become a genuine Debian derivative, complete with all of the required infrastructure and improved packaging techniques. The decision was made to build Kali on top of the Debian distribution because it is well known for its quality, stability, and wide selection of available software.
The first release (version 1.0) happened one year later, in March 2013, and was based on Debian 7 “Wheezy”, Debian’s stable distribution at the time. In that first year of development, they packaged hundreds of pen-testing-related applications and built the infrastructure. Even though the number of applications is significant, the application list has been meticulously curated, dropping applications that no longer worked or that duplicated features already available in better programs.
During the two years following version 1.0, Kali released many incremental updates, expanding the range of available applications and improving hardware support, thanks to newer kernel releases. With some investment in continuous integration, they ensured that all important packages were kept in an installable state and that customized live images (a hallmark of the distribution) could always be created.[19]
Requirements[edit]
- Kali Linux requires a minimum of 3.8GB hard disk space for installation.[20]
- A minimum of 512MB RAM for i386 and AMD64 architectures.
- A bootable CD-DVD drive or a USB stick.
Supported platforms[edit]
Kali Linux is distributed in 32-bit and 64-bit images for use on hosts based on the x86instruction set and as an image for the ARM architecture for use on the Beagle Board computer and on Samsung's ARM Chromebook.[21]
The developers of Kali Linux aim to make Kali Linux available for even more ARM devices.[17]
Kali Linux is already available for BeagleBone Black, HP Chromebook, CubieBoard 2, CuBox, CuBox-i, Raspberry Pi, EfikaMX, Odroid U2, Odroid XU, Odroid XU3, Samsung Chromebook, Utilite Pro, Galaxy Note 10.1, and SS808.[22]
With the arrival of Kali NetHunter, Kali Linux is also officially available on Android devices such as the Nexus 5, Nexus 6, Nexus 7, Nexus 9, Nexus 10, OnePlus One, and some Samsung Galaxy models.
Kali Linux is available on Windows 10, on top of Windows Subsystem for Linux (WSL). The official Kali distribution for Windows can be downloaded from the Microsoft Store.[23]
Features[edit]
Kali Linux has a dedicated project set aside for compatibility and porting to specific Android devices, called Kali Linux NetHunter.[24]
It is the first Open Source Android penetration testing platform for Nexus devices, created as a joint effort between the Kali community member 'BinkyBear' and Offensive Security. It supports Wireless 802.11 frame injection, one-click MANA Evil Access Point setups, HID keyboard (Teensy like attacks), as well as Bad USB MITM attacks.[24]
BackTrack (Kali's predecessor) contained a mode known as forensic mode, which was carried over to Kali via live boot. This mode is very popular for many reasons, partly because many Kali users already have a bootable Kali USB drive or CD, and this option makes it easy to apply Kali to a forensic job. When booted in forensic mode, the system doesn't touch the internal hard drive or swap space and auto mounting is disabled. However, the developers recommend that users test these features extensively before using Kali for real world forensics.[25]
Tools[edit]
Kali Linux includes security tools, such as:[13]
- Cisco Global Exploiter, a hacking tool used to find and exploit vulnerabilities in Cisco Network systems
- Metasploit framework
- Social engineering tools.
- Reverse Engineering tools
These tools can be used for a number of purposes, most of which involve exploiting a victim network or application, performing network discovery, or scanning a target IP address. Many tools from the previous version (BackTrack) were eliminated to focus on the most popular penetration testing applications.

I just installed Kali 1.1.0, and changed
gnome-fallback
to gnome
. Is there a way for me to change the login/lock screen?I would like to change the background, but also the appearanceRumanoidRumanoid

I'm not 100% about older versions, but in later versions, you can simply goto the top-right of the workspace desktop (where you would access the quick info for Wi-Fi). Click the wrench/settings icon, and then enter settings (you can do this through any method you're comfortable with). Finally, select the 'background' icon in settings. Settings window is akin to Windows Control Panel, and going to Display, then Background.
So check if you can goto All Settings, look for a Background or similar option, and changer the lock screen and desktop separately.
I apologize if this does not work on 1.1, but I wanted to mention, Kali may be more difficult or work-intensive, for everyday use, unless your everyday use is fairly simple and you don't mind occasional commands. It is a great distro to begin getting the hang on Linux, to perform tasks and understand the CLI better. But as mentioned, it is not an optimal Linux distro to attempt to use for every day use. Its not really configured for it and you will need to learn certain commands you will commonly deal with.
It still mounts drives and plays files w/o problem, so if you are using it to watch a movie or listen to music and browse the web, it'll with fine. Not optimal, but there's nothing actually 'wrong' with doing it. Other versions can be easier to acclimate to though.
Also, GNOME is basically your desktop system. As you found out, changing this option on the lock screen only changes your environment. It does not pertain to the lock screen itself though, in terms of directly controlling it by switching that drop down option and selecting GNOME or anything else. You would need to manually set the bg pic through commands or by searching for settings.
Hope any of that helps a little.

Changing and configuring the login wallpaper for Kali 2.0 is three step process.I am not sure if this is helpful for the Kali 1.0 users though.Once in the terminal
- Find the resolution of the current login image. To do this you could use the below command.
eog /usr/share/gnome-shell/theme/KaliLogin.png
In the image-viewer look at te bottom left corner to see the resolution. - Once you get the resolution, make sure that your replacement image is of this size and more importantly in the png format. Then move your image to replace the existing image by using the below command.
mv /path/to/your/image/image_name.png /usr/share/gnome-shell/theme/KaliLogin.png
- This is an optional step. Reboot the computer to see if the new image fits perfectly into the login screen. If not, run the below command in terminal
gnome /usr/share/gnome-shell/theme/gnome-shell.css
This will open (in the text editor) the cascade style sheet which helps you set the background image settings for the login screen. In this file look for the below lines#lockDialogGroup {background: #2e3436 url(KaliLogin.png);background-repeat: no-repeat;background-size:cover;}
Change the
background-size
to contain
. Save and close the css file and reboot the computer.sjsamsjsam

I'm the same, I don't like the big 'KALI LINUX' screen that pops up at the coffee shop ;)
find a new image you want to use; look in /usr/share/images/desktop-base/
get the full path and append the name of the image you want to use to the command as shown bellow.
GalugaGaluga
You may alter the file 10-desktop-base-settings to point to a different image.location = /usr/share/gdm/dconf/10-desktop-base-settings
You may also alter the image directly.location = /usr/share/images/desktop-base
These are the default images for the login screen. alter the one that applies to your resolution.kali-wallpaper_1024x768.pngkali-wallpaper_1280x1024.pngkali-wallpaper_1280x800.pngkali-wallpaper_1600x1200.pngkali-wallpaper_1920x1080.pngkali-wallpaper_1920x1200.png
