BlackArch Linux Penetration Testing 2020.01.01 Complete install

BlackArch

BlackArch Linux is an Arch Linux-based penetration testing distribution for penetration testers and security researchers. The repository contains 2521 tools. In this article, I’m going to show you how to install BlackArch. A Step-by-Step walkthrough..!

To be honest, I am completely surprised by what I see now, great progress from BlackArch. How fast it is. Last year was the last time I had BlackArch on a computer. Now tested for a few days, for this article and video. Very surprising ..! I can really recommend everyone to try BlackArch.


Download BlackArch

BlackArch Download Page

On the official download page, there are various download options. Personally, I always prefer to download the ISO from the official website. So you can be sure that you are not downloading some malicious files.


Download BlackArch

Do not use UNetBootIn to write ISO files

Do not use UNetBootIn to write ISO files to flash drives. UNetBootIn modifies the bootloader configuration, which is bad. You can use this instead (where /dev/sdX is your flash drive and /path/to/file.iso is a BlackArch ISO)

I would like to make a further comment: This applies to all Linux distributions. The best is to write you ISO file as below.


Example Linux Image writing

sudo dd bs=512M if=/path/to/file.iso of=/dev/sdX

dd

In the video that comes with this article, I am going to show you how to install BlackArch A Step-by-step walkthrough I also show you how to do the setup on VirtualBox, and how to use pacman, I show you how to play with the screen resolutions, and install a file manager.

Here you can see the Video

Making the screen bigger in VirtualBox BlackArch


Defaut layout virtualbox blackarch

Since I show this installation from a VirtualBox, I like to have a normal screen. (It must be easy to work with).


There are two options to make your screen bigger. I show them both. The first is the easiest, for that, you go to the Settings of VirtualBox and –> Display choose the option VBoxSVGA. This ensures that you start right away with a normal screen.



Still, I also want to show you the option in the terminal. This can be useful for many reasons. For this, I will adjust the screen size, with the following command(s)

xrandr

xrandr blackarch

Virtualbox connected primary 800×600. The maximum will be 8192×8192
Choose the right screen resolution for your computer. And follow the next command. Choose the right one for your device.

xrandr --screen 0 -s 1360x768

xrandr big screen blackarch linux

Execute the BlackArch install script

To start the installation, you must execute the Blackarch install script. In order to avoid any problems that can cause you to restart the installation, make sure to have the internet available on the machine where you want to install Blackarch.

You can list the available network interfaces with the command ip a. If you want or only have wifi available as an option, you may read the arch wiki to know how to set up a wireless connection. (ie: wifi-menu/netctl) If your keyboard differs from the default one, qwerty us, you can set the keymap corresponding to your language/country. For example, enter the command loadkeys following the 2 letters of your country code.


blackarch-install

Execute the command blackarch-install to start the Blackarch install script.

pacman -Sy

blackarch-install

Available installation modes

3 options should now be displayed

1. Install from repository using pacman

This is the recommended option to select for the netinstall iso, it will fetch the required packages from official arch repositories and the blackarch repositories as well.

2. Install from Live-ISO

If you downloaded the live ISO. If you choose this option you will not need internet during the install process. However, in order to have an updated system, after the installation has finished, once you reach your install environment (after you boot into the fresh install) start a general update using pacman -Syyu .

3. Install from source using blackman

This is not a recommended option for beginners, instead of fetching the prebuilt package from a repository as pacman does, this will get the source code and compile from source. It’s similar to emerge available on a Gentoo system (blackman simply builds from source, emerge is infinitely more advanced and offers a ton of features)


Because we make this installation in VirtualBox and we have downloaded an ISO, we choose option 2


blackarch install modes

Available output modes

1 Quiet (default)

2 Verbose (output of system commands: mkfs, pacman, etc.)

I would like to see what happens, so I choose option 2


availiable output blackarch

Available locale options

1 Set a locale
2 List available locales

I also go here for the default option 1. To see a list, select option 2


Available locale options blackarch

Set the locale and press enter, If you have the default option.

Available keymap options

You now have to select the keymap you want. If you have a qwerty based keyboard, you can stick with us keycode, however, this may not always be the case. If you are unsure, you may List available keymaps on Blackarch by selecting 2. Most of the time, the English country code is used. For a french azerty, the keymap will be fr, for Spanish es, etc… If you know the keymap, set 1

1 Set a keymap
2 List available keymaps


Available keymap options blackarch

You have to write the keymap as explained above


keymap setup blackarch

Network Setup BlackArch

[?] Set your hostname

The hostname is basically the name you want to give to your computer on your local network. It will resolve as the name given. You may choose whatever you like and this can be changed at any time by editing the /etc/hostname file.


blackarch Set your hostname

Hard Drive Setup

Available hard drives for installation


Hard Drive Setup BlackArch

Hard Drive Setup > DualBoot

This is a great option if you would like to have a DualBoot on your device. Since this installation is a VirtualBox, I choose n

Install BlackArch Linux with Windows/Other OS [y/n]


Hard Drive Setup > DualBoot BlackArch

Hard Drive Setup > Partitions BlackArch

There is only just one option to go ..!

Select y when the script asks you if you want to create your partition with cfdisk, selecting n will stop the install of BlackArch.

Create partitions with cfdisk (root and boot, optional swap) [y/n] y


Hard Drive Setup > Partitions

Hard Drive Setup

Start with an in-memory zeroed partition talble [y/n] y


Start with an in-memory zeroed partition talble

Select label type

If your storage device already has a label type, you won’t see this, otherwise, set it to dos.


Select label type BlackArch

Setup the partitions BlackArch

You now have to setup the partitions. The example given is a basic one and should work in most cases. You will need to create at least 2 partitions (boot and root) but we will use 3 in this example including the swap partition. Let’s start with the first one, boot.


Setup the partitions BlackArch

Using the arrow, go to New, push enter and write 500M, This is enough space for most users since you won’t have more than 3 different kernels at the same time.


Partition size 500M BlackArch

Select primary and press enter.


2020 04 16 23 33

You need to mark this partition as bootable. Go to the option bootable and press enter. The * should appear as on the screen.


bootable 2

Afterward, go to the second partition, press the down arrow to select the free space then select New.

This will be our swap partition. Press enter and write 1G. Press enter again and select primary.


swap

For this partition, you need a different type. Using the arrow, go to Type and press enter.


type

A list will be displayed.
Select Linux swap /solaris [82] and press enter. Let’s go for the last partition.


Select Linux swap /solaris [82] BlackArch

The same process, as we did earlier, select the free space in green, go to New and press enter. This time you don’t need to write anything. We want to take all the free space available. Simply press enter twice.


freespace

Before you quit cfdisk you must save this partition table. Go to Write and press enter.


write changes to disk blackarch

It will ask you to confirm your changes. Write yes and press enter and you may now quit.


write partition to disk blackarch

Hard Drive Setup > Crypto

You have the choice to fully encrypt your root partition with LUKS. It’s recommended to set y as your data may be sensitive and you want to keep it private from anyone (in case your computer gets stolen or is taken by some agency…). Do not make something too easy as it can be brute-forced.


Be aware that if you forget the password to unlock your LUKS partition, the data nor the password can be recovered.


If you have an SSD, if you encrypt the data with LUKS it will drastically reduce the lifetime of the SSD. Encrypting the stored data requires a lot of disk writing (uncrypt as well), you can fix this problem by adding root_trim=yes as an option in your bootloader.

For grub, look for the line of the currently used kernel, similar to the following :: linux /vmlinuz … root=/dev/mapper/ … root_trim=yes (add it at the end of the line)

Because this is an article example for me, I think it’s fine for now, so mine option is n


crypto full encrypted root blackarch

The filesystem for each of those partitions must be defined. Ext4 is the default choice since it’s the most recent.

First, boot will be /dev/sda1 and choose ext4 for the filesystem.

The second partition will be the root, write /dev/sda3 and choose ext4 as a filesystem.

The last one will be the swap, write /dev/sda2 or just push enter if you haven’t created one.


Make a mistake, and there is no turning back. You can start again. So pay attention.

Partition table correct

Are you sure? No crying afterwards? 😀

Dumping data from live ISO

Now the script will download the latest necessary packages for your system. This will take a little time depending on your internet speed. 

Grab yourself a coffee and pop shells..!


coffee

Password root

When the install is finished with this task, you will be asked to set the password of your root account.


base system user

Next, you need to create a normal account, using the root as the only user of your system is wrong and you should never do it.


setup user account blackarch

setup normal user account blackarch

Timezone

Now the script is ask you for the timezone. The default is UTC.


timezone

For this install I choose the default UTC. You can always change this afterwards


Timezone Blackarch

Came Over BlackArch

If you ever wonder what the meaning of that is. It’s just a “Joke” made by a developer. In other words, this means that its the end of the installation.
