Kali's ARM History

 

Kali's ARM History

When BackTrack ARM first came out, it was one image, for a Motorola Xoom. The work was done on the Xoom itself by @muts. He started from an Ubuntu image for it, built all of the packages for BackTrack on it, then installed them. @steev then took the work and expanded it to support 3 or 4 different ARM devices he had, following a similar proceedure. @steev showed @muts the work he'd done and @muts was as excited about it as @steev was.

When Kali came about, we retooled everything, including build servers for armel, armhf, and arm64. No more building packages manually on the ARM devices themselves. So everything was in place, but the images for ARM devices were still being built manually. Putting out an updated image meant downloading the last release, writing it to an sdcard, booting the device, running updates, building the kernel, installing the new kernel, cleaning up the logs and apt cache, then powering the system off, plugging the sdcard back into my other system, and creating a dd image of the sdcard, putting it on to a server. This was very error prone due to the nature of sd cards from different manufacturers having different actual sizes.

We wanted to make it so anyone could, starting from a Kali amd64 installation, build an image that would work on any of our supported ARM devices, end up with exactly what we put out, and most importantly, customize it for their needs. So we created the kali-arm build scripts - they are not fancy, but they're easy to read, follow and modify.

Kali Linux History

  Kali Linux History ​Kali Linux is based on years of knowledge and experience of building a pentestion testing Operating Systems, which has spanned over multiple previous projects. During all these project's life-time, there has been only a few different developers, as the team has always been small. As a result, Kali has been years in the making and has come a long way.​ The first project was called  Whoppix , which stood for  WhiteHat Knoppix . As can be inferred from the name, it was based on Knoppix for the underlining OS. Whoppix had releases ranging from v2.0 to v2.7.​ This made way for the next project,  WHAX   (or the long hand,  WhiteHat Slax ).  The name change was because the base OS changed from Knoppix to Slax. WHAX started at v3, as a nod towards it carrying on from Whoppix.​ There was a similar OS being produced at the same time,  Auditor Security Collection   (often getting shorted to just  Auditor ) , once again using Knoppix, and efforts were combined (with WHAX)

Kali's Default Credentials

  Kali's Default Credentials Kali changed to a non-root user policy by default since the release of  2020.1 . This means: During the installation of  amd64  and  i386  images, it will prompt you for a standard user account to be created. Any default operating system credentials used during  Live Boot , or  pre-created image  (like  Virtual Machines  &  ARM ) will be: User:  kali Password:  kali Vagrant  image  (based on their  policy ) : Username:  vagrant Password:  vagrant Amazon  EC2 : User:  kali Password:  <ssh key> Default Tool Credentials Some tools shipped with Kali, will use their own default hardcoded credentials (others will generate a new password the first time its used). The following tools have the default values: BeEF-XSS Username:  beef Password:  beef Configuration File:  /etc/beef-xss/config.yaml MySQL User:  root Password:  (blank) Setup Program:  mysql_secure_installation OpenVAS Username:  admin Password:  <Generated during setup> Setup Program

Downloading Kali Linux

Image
  Downloading Kali Linux IMPORTANT! Never download Kali Linux images from anywhere other than the official sources. Always be sure to verify the SHA256 checksums of the file you've downloaded against our  official values . It would be easy for a malicious entity to modify a Kali installation to contain exploits or malware and host it unofficially. Where to Get Official Kali Linux Images ISO Files for Intel-based PCs In order to run Kali "Live" from a USB drive on standard Windows and Apple PCs, you'll need a Kali Linux bootable ISO image, in either 32-bit or 64-bit format. If you're not sure of the architecture of the system you want to run Kali on, on Linux or macOS, you can run the command  uname -m  at the command line. If you get the response, "x86_64", use the 64-bit ISO image (the one containing "amd64" in the file name); if you get "i386", use the 32-bit image (the one containing "i386" in the file name). If you'r
