Amusing enough, last week there was a security advisory regarding this feature. One of its most interesting features for this project is secure boot, called High Assurance Boot, that allows better integrity of our USB armory platform. The USB armory is a small computer on a USB stick, providing an ARM A8 800 MHz CPU and 512MB RAM, and it’s versatile enough to implement all kinds of interesting scenarios.

Since one should never plug in unknown USB devices into a computer (well, any USB device we purchase is unknown but that is another story) and I didn’t want to “burn” a computer just to take a look at the contents I decided to use my USB armory to build an air gap sandbox that would be harder to infect and for malware to escape from it. He had that USB pen stored untouched and of course my curiosity took over. Some time ago a friend received a mysterious USB pen with a note talking about some kind of heavily persistent malware.
