USB Firewall For Connecting USB Devices

The average user inserts a USB stick into their computer from a trusted source. However, there are companies and situations who receive USB flash drives or USB hard drives and they are not certain if the device is infected.

Globotron is a company based in New Zealand who designed the product. The product is called Armadillo and is an open-source USB firewall.

Some research has shown, as many as 29 different types of USB attacks can happen from plugging in mass storage devices (like USB flash drives and USB hard drives) or also HID devices (human input devices like keyboards and mouse).

The USB stack which is the low level code used in the host computer, is very complex and over time researchers and hackers have discovered ways to compromise a computer system through these vulnerabilities.

The Armadillo is an open-source device which is a firewall between a USB device and computer. The firewall isolates the firmware of the USB device so as not to infect your PC if the device has been infected with malicious firmware. You just need to plug in Armadillo between your computer and the USB device using the provided micro-USB cable. Armadillo is an upgrade over USG, the original or first-generation USB hardware firewall device.

The Armadillo has bot detection. This means if the USB firewall device detects malicious codes are being entered via keyboard or mouse (HID devices) the device will block transmission and a red LED indicator light will turn on.

The Armadillo has the ability to temporarily make your USB read only. This is valuable if the computer is infected and you need pull information (recovery software) from the USB stick and want to insure virus’ do not infect the flash drive. The USB is read-only, but it is read/write when not connected to the Armadillo.

Note: If you need a USB stick that is always write protected at the controller level, yet need to temporarily turn off the write protection for data changes, the Lock License drive from Nexcopy is your solution.

This last point about the Armadillo is a bit strange, but we like it. The body is sealed with glitter epoxy so it is easy to identify if the box itself was tampered with. Very creative!

The Armadillo USB Firewall is available from Globotron for $150 USD and ships from New Zealand.
