Virtual Machines

Kali Virtual Machine

Kali Linux is a Debian-based distribution the comes with a handful of helpful security tools used for Penetration Testing, Forensics and/or Reverse Engineering.

The VM can be downloaded in OVA format from here. You need to authenticate using the UPB credentials.


The credentials used to login on the Kali Linux virtual machine are:

  • username: root
  • password: toor


  • 64-bit OS
  • 2 GB RAM
  • 30 GB HDD space

Headless VM

If your physical machine is low on resources (or you simply don't want to live inside the Kali VM, e.g. login in its browser), one thing that might help is running the VM in the background with no graphical interface and simply connect to it via SSH from a host terminal.

The ssh deamon is already active inside the VM and a port forwarding rule has been implemented on port 2222:

$ ssh -p 2222 root@localhost

To get rid of the graphical interface, configure the machine to boot in runlevel 3, by making the following change in /etc/default/grub:


Then run:

# update-grub

Finally, reboot the machine (or run telinit 3 to switch to runlevel 3).

Virtual Box Instruction

To start the machine headless (i.e. no graphical window showing the VM) in Virtual Box, you can either use the “Start” options from the virtualbox graphical application, or:

$ VBoxManage startvm <vm-name> --type headless

Where <vm-name> is the actual name of the VM which you can determine by running:

$ VBoxManage list vms

Debian ARM Virtual Machine

This is a Debian ARM virtual machine which can be run using QEMU. You can use this machine to run and debug ARM binaries.

The VM can be downloaded from here. Use the script to start the machine.

The credentials used to login on the virtual machine are:

  • username: root
  • password: 123456

After the machine is running you can also access it via SSH:

ssh -p 2222 root@localhost

You can also copy files to the virtual machine using scp:

scp -P 2222 file root@localhost:
