StealthDrive packages a USB flash drive inside what appears to be a short USB-A-to-Mini-USB cable. The storage is housed in the USB-A connector, while the Mini-USB end is a disconnected decoy.
Connecting the USB-A end exposes 64GB of USB 3.0 storage. The approximately 1.5ft cable shape is the distinguishing enclosure concept. Concealment is a physical presentation choice, not a claim that files are encrypted or otherwise protected.
