Just here to share a project I’m working on. It’s a 100% open source (hardware, firmware, mechanical, etc) USB drive with a hidden security feature.

When you plug it in, it appears as a normal 8GB USB drive. Only if you create a file called “unlock.txt” with the contents “password:addyourpasswordhere” will it unlock and show the remainder of the drive. Everything in this second section of the disk is now AES256 encrypted in place, using a custom KDF + your password.

I’ll answer some questions before people ask them 🙂

Q: Isn’t this just Vercrypt? A: No, a normal drive setup with veracrypt will show up as jumbled data. This is pretty obviously encrypted media. If you enter your duress password, there will still be another xMB of jumbled data.

Q: Isn’t entering your password into a plain text file insecure. A: My drive doesn’t allow this write to actually happen to the memory

Q: Why did you use a SD card A: Because AI made EMMC cards like 80$ for a 32GB. It takes two seconds for me to spin another board with EMMC in the future.

Anyways feel free to ask any more questions about the project 🙂 !

Hey,

The team behind the Proxmark3 RDV4 and Iceman firmware just launched the Proxmark5. It’s a major upgrade for RFID/NFC pentesting and research.

Key upgrades:

  • Much faster processor + better FPGA
  • Modular & UHF-ready design
  • Flipper Zero integration support
  • Dynamic antenna tuning, RGB feedback, dual USB-C, etc

It’s fully open source and built for serious hardware hacking.
