Kali Linux is an advanced penetration testing Linux distribution used for penetration testing, ethical hacking and network security assessments.
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.
Welcome to our fourth and final release of 2018, Kali Linux 2018.4, which is available for immediate download. This release brings our kernel up to version 4.18.10, fixes numerous bugs, includes many updated packages, and a very experimental 64-bit Raspberry Pi 3 image.
New Tools and Tool Upgrades
We have only added one new tool to the distribution in this release cycle but it’s a great one. Wireguard is a powerful and easy to configure VPN solution that eliminates many of the headaches one typically encounters setting up VPNs. Check out our Wireguard post for more details on this great addition.
Kali Linux 2018.4 also includes updated packages for Burp Suite, Patator, Gobuster, Binwalk, Faraday, Fern-Wifi-Cracker, RSMangler, theHarvester, wpscan, and more. For the complete list of updates, fixes, and additions, please refer to the Kali Bug Tracker Changelog.
64-bit Raspberry Pi 3
We have created a very experimental Raspberry Pi 3 image that supports 64-bit mode. Please note that this is a beta image, so if you discover anything that isn’t working, please alert us on our bug tracker.
Download Kali Linux 2018.4
If you would like to check out this latest and greatest Kali release, you can find download links for ISOs and Torrents on the Kali Downloads page along with links to the Offensive Security virtual machine and ARM images, which have also been updated to 2018.4. If you already have a Kali installation you’re happy with, you can easily upgrade in place as follows.
Ensuring your Installation is Updated
To double check your version, first make sure your Kali package repositories are correct.
deb http://http.kali.org/kali kali-rolling main non-free contrib
Then after running ‘apt -y full-upgrade’, you may require a ‘reboot’ before checking:
root@kali:~# uname -a
Linux kali 4.18.0-kali2-amd64 #1 SMP Debian 4.18.10-2kali1 (2018-10-09) x86_64 GNU/Linux
If you come across any bugs in Kali, please open a report on our bug tracker. We’ll never be able to fix what we don’t know about.
