Finally my USB-Armory arrived

10 April 2015

A view month ago I ordered at Crowdsupply this amazing little usb-device. This usb-device is a little computer(800MHz ARM® processor, 512MB RAM). I ordered it with a pre-installed Linux SD-Card. And finally they got enough money to produce and ship it.

Here are some facts(from the website):

  • Freescale i.MX53 ARM® Cortex™-A8 800Mhz, 512MB DDR3 RAM
  • USB host powered (<500 mA) device with compact form factor (65 x 19 x 6 mm)
  • ARM® TrustZone®, secure boot + storage + RAM
  • microSD card slot
  • 5-pin breakout header with GPIOs and UART
  • customizable LED, including secure mode detection
  • excellent native support (Android, Debian, Ubuntu, Arch Linux)
  • USB device emulation (CDC Ethernet, mass storage, HID, etc.)
  • Open Hardware & Software

The usb-armory can be used for example as a “password-manager”, encrypted usb-storage, ssh-proxy, tor-proxy, pen-testing-tool, security token, and so on..

My first impressions:

As soon as I connected it with my Linux-Notebook I got a new network interface called “usb0”. I just configured this interface on my Linux-Notebook and set the IP-Address to The pre-installed Linux-Image on my USBArmory has

dr@tardis:/# ifconfig usb0 netmask
dr@tardis:/# ping

Now I can connect via SSH. But it’s not the only way to gain a shell. There is a Webshell listening on port 4200. So I can use a Browser to connect to”” and open a shell. This is very useful, because maybe I use this device on foreign computers and there might not be a ssh-client but a web-browser.


I also ordered a USB-Host-Adapter. This device transforms the USB-Armory into a standalone computer powered by a micro-USB-Cable and provides a USB-Port for Wifi, USB-keyboard or anything else.

All in all I am super happy with my new toy and I am going to play with it. It’s a powerful device and I can imagine that I am going to have a lot of fun with it.
