The Spit-Detecting USB Flash Drive Is Nearly Here
Frequent visitors may well recall that security researcher and common open resource components fanatic [Walker] has been preparing a instead unusual flash travel for some time — one particular that will only show its contents if the person would make positive to lick their fingers before plugging it in. We’re delighted to report that concept has not too long ago specified way to actual components, and the Ovrdrive “self-destructing” flash drive is now a phase closer to actuality.
The final time we checked in with [Walker], he hadn’t yet put any hardware alongside one another, even though he was fairly positive what factors he would have to have and how it would all go collectively. This was assisted considerably by the fact that USB flash drives are this sort of a ubiquitous piece of tech, earning their basic principle parts abundant and rather very well documented. As defined in the video underneath, all you actually require to spin up your personal flash push is the USB connector, the controller chip, and a awesome slab of flash memory for it to accessibility. While normally you’re on your possess for spit detection.
What we primarily like about this project is that [Walker] is releasing the total thing as open up source components. So even if you’re not intrigued in the total lick-for-access feature, you’ve continue to bought a boilerplate flash generate style and design to develop on. We have not noticed a lot of Diy initiatives tackle USB Mass Storage earlier, and perhaps this style can transform that.
But of course, only if the matter functions. In accordance to the video clip right after the split, [Walker] would seem to have strike a snag with this revision of the hardware. While it enumerates as a storage product when plugged into the pc, the running technique claims its capability is zero. He thinks there may possibly be a swapped trace in between the controller and flash chip to blame, so with any luck , he can get factors sorted out ahead of too extensive. We have been covering this project due to the fact the summer, and are eager to see it cross the end line.
Editor’s Take note: This is unrelated to the flash generate by itself, but let’s take a minute to appreciate the shout-out to the builders of all the open up supply software program utilized to make the venture and the accompanying video that [Walker] extra to the stop of the presentation. We must all try to remember to pay back regard to the individuals that make so significantly of what we do possible.
