Kali on USB Armory

Install Kali on the SDcard

  • Download the latest image
  • Verify the download:
    $ sha256sum kali-2017.01-usbarmory.img.xz 
    2b2b1d42c255fbb34e6ea24d35dc33639f6b52f05d9378a3e3ccaea793d824ee  kali-2017.01-usbarmory.img.xz
  • Write the image to the SDcard:
    # lsblk      # /dev/sdc is my SDcard device
    # xzcat kali-2017.01-usbarmory.img.xz | dd of=/dev/sdc bs=1M status=progress
    
  • Plug in the device. When the USB Armory has booted up, you should have a new USB network interface on your host machine, for example enp0s20f0u1i1.
  • Configure the USB network interface:
    nmcli con mod 'Wired connection 1' connection.id usbarmory
    nmcli con mod usbarmory ipv4.addresses 10.0.0.2/24
    nmcli con mod usbarmory ipv4.method manual
    nmcli con up usbarmory
  • Log in with user root/toor:
    ssh root@10.0.0.1

Forward traffic from USB Armory

  • Configure forwarding:
    echo "net.ipv4.conf.eno1.forwarding = 1" >> /etc/sysctl.d/50-forwarding.conf
    sysctl -p
  • Add direct rules to firewalld. The –permanent option to keep these rules across restarts. Interface eno1 is the interface connected to the rest of the network.
    firewall-cmd --permanent --direct --add-rule ipv4 nat POSTROUTING 0 -o eno1 -j MASQUERADE
    firewall-cmd --permanent --direct --add-rule ipv4 filter FORWARD 0 -i enp0s20f0u1 -o eno1 -j ACCEPT
    firewall-cmd --permanent --direct --add-rule ipv4 filter FORWARD 0 -i eno1 -o enp0s20f0u1 -m state --state RELATED,ESTABLISHED -j ACCEPT
    firewall-cmd --reload

Fix: does not boot after apt-get update

  • Mount the SDcard and add the following modules to /etc/modules:
    ledtrig_heartbeat  # comment this line if you don't want that intense blinking LED.
    ci_hdrc_imx
    #g_mass_storage
    g_ether

Expand root filesystem

  • Connect the SCcard to the host machine.
  • Modify partition:
    # parted /dev/mmcblk0
    print
    
    rm 1
    mkpart primary ext2 5243kB 100%
    
    print
    quit
  • Reboot:
    reboot
  • Login and resize filesystem:
    resize2fs /dev/mmcblk0p1
