Kali 2017.1: Things to do after you install…

Share

Kali 2017.1 is out and now what?

Yes, it is a great distro right out of the box (even added support for Realtek’s RTL8812AU wireless chipsets), but there are a few things that you can do to make it even more versatile. You can customize it to better meet your needs. If you want to add encrypted containers to secure your data, you can add TrueCrypt’;s replacement VeraCrypt. If you want to build your own lab environment, you can add VirtualBox. There are a lot of things you can do. Below, I will walk through a few things that I would personally suggest to make life a little easier and build on the already robust Kali distribution.

Here are some suggested things to do after you download.

* change the default root password from “toor”

passwd

– remember the new password

* add a new user

adduser newuser

– Add the user to the SUDOers group

visudo

– Find the part of the file that is labeled “User privilege specification”.
– Find where it says “root ALL=(ALL) ALL”.
– Type “o” to insert a new line below it.
– Now type what you want to insert, eg “newuser ALL=(ALL) ALL”.
– The file should look like:
# User privilege specification
root ALL=(ALL:ALL) ALL
newuser ALL=(ALL:ALL) ALL

– Hit esc to exit insert-mode.
– Type “:x” to save and exit.

– or a faster way…

useradd -m newuser -G sudo -s /bin/bash
passwd newuser

* change the default SSH keys

cd /etc/ssh/ && mkdir back
mv ssh_host_* back
dpkg-reconfigure openssh-server

– now to compare the new keys with the old ones to make sure they are different

md5sum ssh_host_* && md5sum back/ssh_host_*

– If they don’t match, remove them

rm /etc/ssh/back/ssh_host_*

* add MultiArch for i386 support if you have the 64bit OS

dpkg –add-architecture i386

* update

apt update && apt upgrade -y && apt dist-upgrade -y

* install Java (some software requires it)

echo “deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main” >> /etc/apt/sources.list
echo “deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main” >> /etc/apt/sources.list

If you want to vew the change log: view the change log here.  Now that you’ve added a few things to Kali, let the fun begin.

P.S. I would suggest logging out of root and in the the “newuser” you created. Any time you need to run something at a higher privilege, use “sudo program”. For example:

sudo ifconfig eth0 down
sudo macchanger eth0 -r
sudo ifconfig eth0 up
