Unfortunately, the USB drive itself isn’t all that secure, even if you add basic password protection to it. Instead, go ninja and hide in plain sight by disguising a virtual USB drive.
What USB flash drives can you use?
If you are a DIY enthusiast, you can work with any standard flash drive. But this is ideal — not to buy the best and most reliable USB keys. What you need is something cheap and tiny.
If you’re buying new, look for a flash drive with simple silicone molding instead of a hard plastic case. You can also use a plastic case if you have several of these. Super Talent Pico-C 16 GB (UK) is fully compliant.
No matter which USB key you use, you will have to hack or open it. What you need is just a PCB with a USB port, nothing else. As long as you can achieve this, it doesn’t matter what type of flash drive you have.
1. Disguised as a broken USB cable
The EvilMadScientist guide will show you how to make this disguise. Take any old cable you have. Cut along the side of the USB port just deep enough that you can fold back the rubber.
Using a small screwdriver, remove the tabs and parts that hold the USB key to the wire. If you are using a compact flash drive such as the Super Talent Pico, insert the drive into the USB port. If you are using a flash drive with a PCB and a USB port together, then disconnect the USB port of the frayed wire and insert it into the drive.
Seal everything back and test the disc once. If it works, it’s time to seal it up for good. For insulation, apply heat shrink tubing or electrical tape. Then fill the remaining space with a five-minute fast drying epoxy gel.
Voila! You have a flash drive that looks like a broken cable. Make sure the ends of the cable look frayed, with a few wires sticking out to complete the trick.
2. USB in lipstick or lipstick
The easiest way to hide a USB key in plain sight is to put it in an old lipstick or lipstick case. Most people aren’t going to open your lipstick to see if it’s really inside.
