Kali Linux is an advanced penetration testing Linux distribution used for penetration testing, ethical hacking and network security assessments. Official images hosted by us for faster downloads.

Kali Linux is preinstalled with over 600 penetration-testing programs, including nmap (a port scanner), Wireshark (a packet analyzer), John the Ripper (a password cracker), Aircrack-ng (a software suite for penetration-testing wireless LANs), Burp suite and OWASP ZAP (both web application security scanners). 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.
It was developed by Mati Aharoni and Devon Kearns of Offensive Security through the rewrite of BackTrack, their previous forensics Linux distribution based on Ubuntu. The third core developer Raphaël Hertzog joined them as Debian expert.
Kali Linux is based on Debian Wheezy. Most packages Kali uses are imported from the Debian repositories.
Kali Linux is developed in a secure location with only a small number of trusted people that are allowed to commit packages, with each package being signed by the developer. Kali also has a custom built kernel tha is patched for injection. This was primarily added because the development team found they needed to do a lot of wireless assessments.

What's New:
With the end of 2021 just around the corner, we are pushing out the last release of the year with Kali Linux 2021.4, which is ready for immediate download or updating.
The summary of the changelog since the 2021.3 release from September 2021 is:
  • Improved Apple M1 support
  • Wide compatibility for Samba
  • Switching package manager mirrors
  • Kaboxer theming
  • Updates to Xfce, GNOME and KDE
  • Raspberry Pi Zero 2 W + USBArmory MkII ARM images
  • More tools
Kali on the Apple M1
As we announced in Kali 2021.1 we supported installing Kali Linux on Parallels on Apple Silicon Macs, well with 2021.4, we now also support it on the VMware Fusion Public Tech Preview thanks to the 5.14 kernel having the modules needed for the virtual GPU used. We also have updated the open-vm-tools package, and Kali's installer will automatically detect if you are installing under VMware and install the open-vm-tools-desktop package, which should allow you to change the resolution out of the box. As a reminder, this is still a preview from VMware, so there may be some rough edges. There is no extra documentation for this because the installation process is the same as VMWare on 64-bit and 32-bit Intel systems, just using the arm64 ISO.
As a reminder, virtual machines on Apple Silicon are still limited to arm64 architecture only.
Extended Compatibility for the Samba Client
Starting Kali Linux 2021.4, the Samba client is now configured for Wide Compatibility so that it can connect to pretty much every Samba server out there, regardless of the version of the protocol in use. This change should make it easier to discover vulnerable Samba servers "out of the box", without having to configure Kali.
This setting can be changed easily via the command-line tool kali-tweaks. In the Hardening section, one can choose the value Default instead, which reverts back to Samba's usual default, and only allow using modern versions of the Samba protocol.

New Tools in Kali
It would not be a Kali release if there were not any new tools added! A quick run down of what's been added (to the network repositories):
  • Dufflebag - Search exposed EBS volumes for secrets
  • Maryam - Open-source Intelligence (OSINT) Framework
  • Name-That-Hash - Do not know what type of hash it is? Name That Hash will name that hash type!
  • Proxmark3 - if you are into Proxmark3 and RFID hacking
  • Reverse Proxy Grapher - graphviz graph illustrating your reverse proxy flow
  • S3Scanner - Scan for open S3 buckets and dump the contents
  • Spraykatz - Credentials gathering tool automating remote procdump and parse of lsass process.
  • truffleHog - Searches through git repositories for high entropy strings and secrets, digging deep into commit history
  • Web of trust grapher (wotmate) - reimplement the defunct PGP pathfinder without needing anything other than your own keyring
Desktop & Theme Enhancement
This release brings updates for all the 3 main desktops (Xfce, GNOME, and KDE), but one that is common to all of them is the new window buttons design. Previous buttons were designed to fit the window theme of Xfce but did not work well with the other desktops and lacked personality. The new design looks elegant on any of the desktops and makes it easier to spot the currently focused window.

The panel layout has been tweaked to optimize horizontal space and make room for 2 new widgets: the CPU usage widget and the VPN IP widget, which remains hidden unless a VPN connection is established.
Following the steps of other desktops, the task manager has been configured to "icons only", which, with the slight increase in the panel's height, makes the overall look cleaner and improves multitasking in smaller displays.
The workspaces overview has been configured to the "Buttons" appearance, as the previous configuration "Miniature view" was too wide and a bit confusing for some users. Now that each workspace button takes less space in the panel, we have increased the default number of workspaces to 4, as it's a usual arrangement in Linux desktops.

To finish with the modifications, a shortcut to PowerShell has been added to the terminals dropdown menu. With this addition, you can now choose between the regular terminal, root terminal, and PowerShell.
