A privacy-focused, open-hardware USB flash drive with a hidden feature that protects your data
Interrupt Labs
Security & Privacy
Ovrdrive USB is an open-hardware USB flash drive with an inconspicuous enclosure and a hidden security feature tucked away inside it. If you plug the device in normally, it will appear blank, but if you quickly plug it in three times in a row, you will be able to read and write data. We built Ovrdrive for journalists working in hostile environments, security researchers, and anyone interested in open hardware.
All project assets are open source, including the software tools we used to design our PCB. Ovrdrive’s removable enclosure gives you easy access to the board. You can program its microcontroller using using a 6-pin header with a 1.27-mm pitch.
Ovrdrive also includes circuitry that can invert the voltage supply to the flash chip, which heats it up to over 100° Celsius. While that’s not quite hot enough to destroy a flash chip, it’s probably hot enough to act as a catalyst for whatever DIY "self-destruct" implant you might choose to design, build, and stuff inside the enclosure.
So, if your threat model—or your idea of a good time—calls for the permanent, hardware-level destruction of data, you can break a trace on our PCB and start experimenting. (This feature is disabled by default for obvious reasons.)

We designed Ovrdrive for everyone, and it’s 100% open source. Check out our GitHub repo! All of the CAD tools we used to design this device are open source as well. We would like to thank the developers and maintainers KiCad, FreeCAD, GNU/Linux, and Arch Linux. Feel free to join our open source hardware community on Discord!
"As a product aimed at journalists, researchers, and others needing an extra storage security layer, the Ovrdrive USB design may be a good choice. ...[It] serves as an excellent security knowledge check for unwanted third-party drive users."
